Wild Flowers / An Aid to Knowledge of Our Wild Flowers and Their Insect Visitors

by Neltje Blanchan

YELLOW AND ORANGE FLOWERS

GOLDEN CLUB
(Orontium aquaticum) Arum family

Flowers - Bright yellow, minute, perfect, crowded on a spadix (club) 1 to 2 in. long; the scape, 6 in. to 2 ft. tall, flattened just below it; the club much thickened in fruit. Leaves: All from root, petioled, oblong-elliptic, dull green above, pale underneath, 5 to 12 in. long, floating or erect. Preferred Habitat - Shallow ponds, standing water, swamps. Flowering Season - April-May. Distribution - New England to the Gulf States, mostly near the coast.

A first cousin of cruel Jack-in-the-pulpit, the skunk cabbage, and the water-arum (q.v.), a poor relation also of the calla lily, the golden club seems to be denied part of its tribal inheritance - the spathe, corresponding to the pulpit in which Jack preaches, or to the lily's showy white skirt. In the tropics, where the lily grows, where insect life teems in myriads and myriads, and competition among the flowers for their visits is infinitely more keen than here, she has greater need to flaunt showy clothes to attract benefactors than her northern relatives. But the golden club, which looks something like a calla stripped of her lovely white robe, has not lacked protection for its little buds from the cold spring winds while any was needed. By the time we notice the plant in bloom, however, its bract-like spathe has usually fallen away, as if conscious that the pretty mosaic club of golden florets, so attractive in itself, was quite able to draw all the visitors needed without further help. Merely by crawling over the clubs, flies and midges cross-fertilize them.

PERFOLIATE BELLWORT; STRAW BELL
(Uvularia perfoliala) Bunch-flower family

Flowers - Fragrant, pale yellow, about 1 in. long, drooping singly (rarely 2) from tips of branches; perianth narrow, bell-shaped, of 6 petal-like segments, rough within, spreading at the tip; 6 stamens; 3 styles united to the middle. Stem: 6 to 20 in. high, smooth, shining, forking about half way. Leaves: Apparently strung on the slender stem, oval, tapering at tip. Preferred Habitat - Moist, rich woods; thickets. Flowering Season - May-June. Distribution - Quebec to the Gulf of Mexico, west to Mississippi.

Hanging like a palate (uvula) from the roof of a mouth, according to imaginative Linnaeus, the little bellwort droops, and so modestly hides behind the leaf its footstalk pierces that the eye often fails to find it when so many more showy blossoms arrest attention in the May woods. Slight fragrance helps to guide the keen bumblebee to the pale yellow bell. The tips spreading apart very little and the flower being pendent, how is she to reach the nectar secreted at the base of each of its six divisions? Is it not more than probable that the inner surface is rough, as if dusted with yellow meal, to provide a foothold for her as she clings? Now securely hanging from within the inhospitable flower, her long tongue can easily drain the sweets, and in doing so she will receive pollen, to be deposited, in all probability, on the stigmatic style branches of the next bellwort entered.

With a more westerly range than the perfoliate species, the similar LARGE-FLOWERED BELLWORT (U. grandiflora) grows in like situations. Its greenish lemon-yellow flowers, an inch to an inch and a half long, appear from April to May, or when the female bumblebees, that fly before their lords, are the only insects large and strong enough to force an entrance. Mr. Trelease, who noted them on the flowers near Madison, Wisconsin, saw that one laden with pollen from another blossom came in contact with the three sticky branches of the style, protruding between the anthers, when she crawled between the anthers and sepals, as she must, to reach the nectar secreted at the base. But the linear anthers shedding their pollen longitudinally, there is a chance that the flower may fertilize itself should no bee arrive before a certain point is reached.

The SESSILE-LEAVED BELLWORT, or WILD OAT (U. sessifolia), as its name implies, has its thin, pale green leaves tapering at either end, seated on the stem, not surrounding it, or apparently strung on it. The smaller flower is cream colored. A sharply three-angled capsule about an inch long follows. Range from Minnesota and Arkansas to the Atlantic.

WILD YELLOW, MEADOW or FIELD LILY; CANADA LILY
(Lilium Canadense) Lily family

Flowers - Yellow to orange-red, of a deeper shade within, and speckled with dark reddish-brown dots. One or several (rarely many) nodding on long peduncles from the summit. Perianth bell-shaped, of 6 spreading segments 2 to 3 in. long, their tips curved backward to the middle; 6 stamens, with reddish-brown linear anthers; 1 pistil, club-shaped; the stigma 3-lobed. Stem: 2 to 5 ft. tall, leafy, from a bulbous rootstock composed of numerous fleshy white scales. Leaves: Lance-shaped, to oblong; usually in whorls of fours to tens, or some alternate. Fruit: An erect, oblong, 3-celled capsule, the flat, horizontal seeds packed in 2 rows in each cavity. Preferred Habitat - Swamps, low meadows; moist fields. Flowering Season - June-July. Distribution - Nova Scotia to Georgia, westward beyond the Mississippi.

Not our gorgeous lilies that brighten the low-lying meadows in early summer with pendent, swaying bells; possibly not a true lily at all was chosen to illustrate the truth which those who listened to the Sermon on the Mount, and we, equally anxious, foolishly overburdened folk of to-day, so little comprehend.

"Consider the lilies of the field, how they grow;
they toil not, neither do they spin
And yet I say unto you,
That even Solomon in all his glory
was not arrayed like one of these."

Opinions differ as to the lily of Scripture. Eastern peoples use the same word interchangeably for the tulip, anemone, ranunculus, iris, the water-lilies, and those of the field. The superb Scarlet Martagon Lily (L. chalcedonicum), grown in gardens here, is not uncommon wild in Palestine; but whoever has seen the large anemones there "carpeting every plain and luxuriantly pervading the land" is inclined to believe that Jesus, who always chose the most familiar objects in the daily life of His simple listeners to illustrate His teachings, rested His eyes on the slopes about Him glowing with anemones in all their matchless loveliness. What flower served Him then matters not at all. It is enough that scientists - now more plainly than ever before - see the universal application of the illustration the more deeply they study nature, and can include their "little brothers of the air" and the humblest flower at their feet when they say with Paul, "In God we live and move and have our being."

Tallest and most prolific of bloom among our native lilies, as it is the most variable in color, size, and form, the TURK'S CAP, or TURBAN LILY (L. superburn), sometimes nearly merges its identity into its Canadian sister's. Travelers by rail between New York and Boston know how gorgeous are the low meadows and marshes in July or August, when its clusters of deep yellow, orange, or flame-colored lilies tower above the surrounding vegetation. Like the color of most flowers, theirs intensifies in salt air. Commonly from three to seven lilies appear in a terminal group; but under skilful cultivation even forty will crown the stalk that reaches a height of nine feet where its home suits it perfectly; or maybe only a poor array of dingy yellowish caps top a shriveled stem when unfavorable conditions prevail. There certainly are times when its specific name seems extravagant.

Its range is from Maine to the Carolinas, westward to Minnesota and Tennessee. A well-conducted Turk's cap is not bell-shaped at maturity, like the Canada lily: it should open much farther, until the six points of its perianth curve so far backward beyond the middle as to expose the stamens for nearly their entire length. One of the purple-dotted divisions of the flower when spread out flat may measure anywhere from two and a half to four inches in length. Smooth, lance-shaped leaves, tapering at both ends, occur in whorls of threes to eights up the stem, or the upper ones may be alternate. Abundant food, hidden in a round, white-shingled storehouse under ground, nourishes the plant, and similarly its bulb-bearing kin, when emergency may require - a thrifty arrangement that serves them in good stead during prolonged drought and severe winters.

Why, one may ask, are some lilies radiantly colored and speckled; others, like the Easter lily, deep chaliced, white, spotless? Now, in all our lily kin nectar is secreted in a groove at the base of each of the six divisions of the flower, and upon its removal by that insect best adapted to come in contact with anthers and stigma as it flies from lily to lily depends all hope of perpetuating the lovely race. For countless ages it has been the flower's business to find what best pleased the visitors on whom so much depended. Some lilies decided to woo one class of insects; some, another. Those which literally set their caps for color-loving bees and butterflies whose long tongues could easily drain nectar deeply hidden from the mob for their special benefit, assumed gay hues, speckling the inner side of their spreading divisions, even providing lines as pathfinders to their nectaries in some cases, lest a visitor try to thrust in his tongue between the petal-like parts while standing on the outside, and so defeat their well-laid plan. It is almost pathetic to see how bright and spotted they are inside, that the visitor may not go astray. Thus we find the chief pollenizers of the Canada and the Turk's cap lilies to be specialized bees, the interesting upholsterers, or 1eaf-cutters, conspicuous among the throng. Nectar they want, of course; but the dark, rich pollen is needed also to mix with it for the food supply of a generation still unborn. Anyone who has smelled a lily knows how his nose looks afterward. The bees have no difficulty whatever in removing lily pollen and transferring it. So much for the colored lilies.

The long, white, trumpet-shape type of lily chooses for her lover the sphinx moth. For him she wears a spotless white robe - speckles would be superfluous - that he may see it shine in the dusk, when colored flowers melt into the prevailing blackness; for him she breathes forth a fragrance almost overwhelming at evening, to guide him to her neighborhood from afar; in consideration of his very long, slender tongue she hides her sweets so deep that none may rob him of it, taking the additional precaution to weld her six once separate parts together into a solid tube lest any pilferer thrust in his tongue from the side.

The common orange-tan DAY LILY (Hemerocallis fulva) and the commoner speckled, orange-red TIGER LILY (L. tigrinum) are not slow in seizing opportunities to escape from gardens into roadsides and fence corners.

YELLOW ADDER'S TONGUE; TROUT LILY; DOG-TOOTH "VIOLET"
(Erythronium Americanum) Lily family

Flower - Solitary, pale russet yellow, rarely tinged with purple, slightly fragrant, 1 to 2 in. long, nodding from the summit of a footstalk 6 to 12 in. high, or about as tall as the leaves. Perianth bell-shaped, of 6 petal-like, distinct segments, spreading at tips, dark spotted within; 6 stamens; the club-shaped style with 3 short, stigmatic ridges. Leaves: 2, unequal, grayish green, mottled and streaked with brown or all green, oblong, 3 to 8 in. long, narrowing into clasping petioles. Preferred Habitat - Moist open woods and thickets, brooksides. Flowering Season - March-May Distribution - Nova Scotia to Florida, westward to the Mississippi.

Colonies of these dainty little lilies, that so often grow beside leaping brooks where and when the trout hide, justify at least one of their names; but they have nothing in common with the violet or a dog's tooth. Their faint fragrance rather suggests a tulip; and as for the bulb, which in some of the lily-kin has tooth-like scales, it is in this case a smooth, egg-shaped corm, producing little round offsets from its base. Much fault is also found with another name on the plea that the curiously mottled and delicately pencilled leaves bring to mind, not a snake's tongue, but its skin, as they surely do. Whoever sees the sharp purplish point of a young plant darting above ground in earliest spring, however, at once sees the fitting application of adder's tongue. But how few recognize their plant friends at all seasons of the year!

Every one must have noticed the abundance of low-growing spring flowers in deciduous woodlands, where, later in the year, after the leaves overhead cast a heavy shade, so few blossoms are to be found, because their light is seriously diminished. The thrifty adder's tongue, by laying up nourishment in its storeroom underground through the winter, is ready to send its leaves and flower upward to take advantage of the sunlight the still naked trees do not intercept, just as soon as the ground thaws. But the spring beauty, the rue-anemone, bloodroot, toothwort, and the first blue violet (palmata) among other early spring flowers, have not been slow to take advantage of the light either. Fierce competition, therefore, rages among them to secure visits from the comparatively few insects then flying - a competition so severe that the adder's tongue often has to wait until afternoon for the spring beauty to close before receiving a single caller. Hive-bees, and others only about half their size, of the Andrena and Halictus clans, the first to fly, the Bombylius frauds, and common yellow butterflies, come in numbers then. Guided by the speckles to the nectaries at the base of the flower, they must either cling to the stamens and style while they suck, or fall out. Thus cross-fertilization is commonly effected; but in the absence of insects the lily can fertilize itself. Crawling pilferers rarely think it worthwhile to slip and slide up the smooth footstalk and risk a tumble where it curves to allow the flower to nod - the reason why this habit of growth is so popular. The adder's tongue, which is extremely sensitive to the sunlight, will turn on its stalk to follow it, and expand in its warmth. At night it nearly closes.

A similar adder's tongue, bearing a white flower, purplish tinged on the outside, yellow at the base within to guide insects to the nectaries, is the WHITE ADDER'S TONGUE (E. albidum), rare in the Eastern States, but quite common westward as far as Texas and Minnesota.

YELLOW CLINTONIA
(Clintonia borealis) Lily-of-the-valley family

Flowers - Straw color or greenish yellow, less than 1 in. long, 3 to 6 nodding on slender pedicels from the summit of a leafless scape 6 to 15 in. tall. Perianth of 6 spreading divisions, the 6 stamens attached; style, 3-lobed. Leaves: Dark, glossy, large, oval to oblong, 2 to 5 (usually 3), sheathing at the base. Fruit. Oval blue berries on upright pedicels. Preferred Habitat - Moist, rich, cool woods and thickets. Flowering Season - May-June. Distribution - From the Carolinas and Wisconsin far northward.

To name canals, bridges, city thoroughfares, booming factory towns after DeWitt Clinton seems to many appropriate enough; but why a shy little woodland flower? As fitly might a wee white violet carry down the name of Theodore Roosevelt to posterity! "Gray should not have named the flower from the Governor of New York," complains Thoreau. "What is he to the lovers of flowers in Massachusetts? If named after a man, it must be a man of flowers." So completely has Clinton, the practical man of affairs, obliterated Clinton, the naturalist, from the popular mind, that, were it not for this plant keeping his memory green, we should be in danger of forgetting the weary, overworked governor, fleeing from care to the woods and fields; pursuing in the open air the study which above all others delighted and refreshed him; revealing in every leisure moment a too-often forgotten side of his many-sided greatness.

INDIAN CUCUMBER-ROOT
(Medeola Virginiana) Lily-of-the-valley family

Flowers - Greenish yellow, on fine, curving footstalks, in a loose cluster above a circle of leaves. Perianth of 6 wide-spread divisions about 1/4 in. long; 6 reddish-brown stamens; 3 long reddish-brown styles, stigmatic on inner side. Stem: 1 to 2 1/2 ft. high, unbranched, cottony when young. Leaves: Of flowering plants, in 2 whorls; lower whorl of 5 to 9 large, thin, oblong, taper-pointed leaves above the middle of stem; upper whorl of 3 to 5 small, oval, pointed leaves 1 to 2 in. long, immediately under flowers. Flowerless plants with a whorl at summit. Fruit: Round, dark-purple berries. Preferred Habitat - Moist woods and thickets. Flowering Season - May-June. Distribution - Nova Scotia and Minnesota, southward nearly to the Gulf of Mexico.

Again we see the leaves of a plant coming to the aid of otherwise inconspicuous flowers to render them more attractive. By placing themselves in a circle just below these little spidery blossoms of weak and uncertain coloring, some of the Indian cucumber's leaves certainly make them at least noticeable, if not showy. It would be short-sighted philanthropy on the leaves' part to help the flowers win insect wooers at the expense of the plant's general health; therefore those in the upper whorl are fewer and much smaller than the leaves in the lower circle, and a sufficient length of stem separates them to allow the sunlight and rain to conjure with the chlorophyll in the group below. While there is a chance of nectar being pilfered from the flowers by ants, the stem is cottony and ensnares their feet. In September, when small clusters of dark-purple berries replace the flowers, and rich tints dye the leaves, the plant is truly beautiful - of course to invite migrating birds to disperse its seeds. It is said the Indians used to eat the horizontal, white, fleshy rootstock, which has a flavor like a cucumber's.

CARRION-FLOWER
(Smilax herbacea) Smilax family

Flowers - Carrion-scented, yellowish-green, 15 to 80 small, 6-parted ones clustered in an umbel on a long peduncle. Stem: Smooth, unarmed, climbing with the help of tendril-like appendages from the base of leafstalks. Leaves: Egg-shaped, heart-shaped, or rounded, pointed tipped, parallel-nerved, petioled. Fruit: Bluish-black berries. Preferred Habitat - Moist soil, thickets, woods, roadside fences. Flowering Season - April-June. Distribution - Northern Canada to the Gulf States, westward to Nebraska.

"It would be safe to say," says John Burroughs, "that there is a species of smilax with an unsavory name, that the bee does not visit, herbacea. The production of this plant is a curious freak of nature…. It would be a cruel joke to offer it to any person not acquainted with it, to smell. It is like the vent of a charnel-house." (Thoreau compared its odor to that of a dead rat in a wall!) "It is first cousin to the trilliums, among the prettiest of our native wild flowers," continues Burroughs, "and the same bad blood crops out in the purple trillium or birthroot."

Strange that so close an observer as Burroughs or Thoreau should not have credited the carrion-flower with being something more intelligent than a mere repellent freak! Like the purple trillium (q.v.), it has deliberately adapted itself to please its benefactors, the little green flesh flies so commonly seen about untidy butcher shops in summer. These, sharing with many beetles the unthankful task of removing putrid flesh and fowl from the earth, acting the part of scavengers for nature, are naturally attracted to carrion-scented flowers. Of these they have an ungrudged monopoly. But the purple trillium has an additional advantage in both smelling and looking like the same thing - a piece of raw meat past its prime. Bees and butterflies, with their highly developed aesthetic sense, ever delighting in beautiful colors, perfume, and nectar, naturally let such flowers as these alone - another object aimed at by them, for then the flies get all the pollen they can eat. Some they transfer, of course, from the larger staminate flowers to the smaller pistillate ones as they crawl over one umbel of the carrion-flower, then alight on another.

Presently fruit begins to set, and we can approach the luxuriant vine without offence to our noses. The beautiful glossy green foliage takes on resplendent tints in early autumn - again with interested motives, for are there not seeds within the little bluish-black berries, waiting for the birds to distribute them during their migration?

The vicious CATBRIER, GREENBRIER, or HORSEBRIER (S. rotundifolia), similar to the preceding, except that its four-angled stem is well armed with green prickles, its beautiful glossy, decorative leaves are more rounded, and its greenish flower umbels lack foul odor, scarcely needs description. Who has not encountered it in the roadside and woodland thickets, where it defiantly bars the way?

In the most inaccessible part of such a briery tangle, that rollicking polyglot, the yellow-breasted chat, loves to hide its nest. Indeed, many birds can say with Br'er Rabbit that they were "bred en bawn in a brier-patch." Throughout the eastern half of the United $tates and Upper Canada the catbrier displays its insignificant little blossoms from April to June for a miscellaneous lot of flies - insects which are content with the slightest floral attractions offered. The florist's staple vine popularly known as "SMILAX" (Myrslphyllum asparagoides), a native of the Cape of Good Hope, is not even remotely connected with true Smilaceae.

YELLOW STAR-GRASS
(Hypoxis hirsuta; H. erecta of Gray) Amaryllis family

Flowers - Bright yellow within, greenish and hairy outside, about 1/2 in. across, 6-parted; the perianth divisions spreading, narrowly oblong; a few flowers at the summit of a rough, hairy scape 2 to 6 in. high. Leaves: All from an egg-shaped corm; mostly longer than scapes, slender, grass-like, more or less hairy. Preferred Habitat - Dry, open woods, prairies, grassy waste places, fields. Flowering Season - May-October. Distribution - From Maine far westward, and south to the Gulf of Mexico.

Usually only one of these little blossoms in a cluster on each plant opens at a time; but that one peers upward so brightly from among the grass it cannot well be overlooked. Sitting in a meadow sprinkled over with these yellow stars, we see coming to them many small bees - chiefly Halictus - to gather pollen for their unhatched babies' bread. Of course they do not carry all the pollen to their tunneled nurseries; some must often be rubbed off on the sticky pistil tip in the center of other stars. The stamens radiate, that self-fertilization need not take place except as a last extremity. Visitors failing, the little flower closes, bringing its pollen-laden anthers in contact with its own stigma.

BLACKBERRY LILY (Gemmingia Ciminensis; Pardanthus Chinensis of Gray) Iris family

Flowers - Deep orange color, speckled irregularly with crimson and purple within (Pardos = leopard; anthos = flower); borne in terminal, forked clusters. Perianth of 6 oblong, petal-like, spreading divisions; 6 stamens with linear anthers; style thickest above, with 3 branches. Stem: 1 1/2 to 4 ft. tall, leafy. Leaves: Like the iris; erect, folded blades, 8 to 10 in. long. Fruit: Resembling a blackberry; an erect mass of round, black, fleshy seeds, at first concealed in a fig-shaped capsule, whose 3 valves curve backward, and finally drop off. Preferred habitat - Roadsides and hills. Flowering Season - June-July. Distribution - Connecticut to Georgia, westward to Indiana and Missouri.

How many beautiful foreign flowers, commonly grown in our gardens here, might soon become naturalized Americans were we only generous enough to lift a few plants, scatter a few seeds over our fences into the fields and roadsides - to raise the bars of their prison, as it were, and let them free! Many have run away, to be sure. Once across the wide Atlantic, or wider Pacific, their passage paid (not sneaking in among the ballast like the more fortunate weeds), some are doomed to stay in prim, rigidly cultivated flower beds forever; others, only until a chance to bolt for freedom presents itself, and away they go. Lucky are they if every flower they produce is not picked before a single seed can be set.

This blackberry lily of gorgeous hue originally came from China. Escaping from gardens here and there, it was first reported as a wild flower at East Rock, Connecticut; other groups of vagabonds were met marching along the roadsides on Long Island; near Suffern, New York; then farther southward and westward, until it has already attained a very respectable range. Every plant has some good device for sending its offspring away from home to found new colonies, if man would but let it alone. Better still, give the eager travelers a lift!

LARGE YELLOW LADY'S SLIPPER; WHIPPOORWILL'S SHOE; YELLOW MOCCASIN
FLOWER
(Cypripedium hirsutum; C. pubescens of Gray) Orchid family

Flower - Solitary, large, showy, borne at the top of a leafy stem to 2 ft. high. Sepals 3, 2 of them united, greenish or yellowish, striped with purple or dull red, very long, narrow; 2 petals, brown, narrower, twisting; the third an inflated sac, open at the top, 1 to 2 in. long, pale yellow, purple lined white hairs within; sterile stamen triangular; stigma thick. Leaves: Oval or elliptic, pointed, 3 to 5 in, long, parallel-nerved, sheathing. Preferred Habitat - Moist or boggy woods and thickets; hilly ground. Flowering Season - May-July. Distribution - Nova Scotia to Alabama, westward to Minnesota and Nebraska.

Swinging outward from a leaf-clasped stem, this orchid attracts us by its flaunted beauty and decorative form from tip to root, not less than the aesthetic little bees for which its adornment and mechanism are so marvelously adapted. Doubtless the heavy, oily odor is an additional attraction to them. Parallel purplish lines, converging toward the circular opening of the pale yellow, inflated pouch, guide the visitor into a spacious banquet-hall (labellum) such as the pink lady's slipper (q.v.) also entertains her guests in. Fine hairs within secrete tiny drops of fluid at their tips - a secretion which hardens into a brittle crust, like a syrup's, when it dries. Darwin became especially interested in this flower through a delightful correspondence with Professor Asa Gray, who was the first to understand it, and he finally secured a specimen to experiment on.

"I first introduced some flies into the labellum through the large upper opening," Darwin wrote, "but they were either too large or too stupid, and did not crawl out properly. I then caught and placed within the labellum a very small bee which seemed of about the right size, namely Andrena parvula…. The bee vainly endeavored to crawl out again the same way it entered, but always fell backwards, owing to the margins being inflected. The labellum thus acts like one of those conical traps with the edges turned inwards, which are sold to catch beetles and cockroaches in London kitchens. It could not creep out through the slit between the folded edges of the basal part of the labellum, as the elongated, triangular, rudimentary stamen here closes the passage. Ultimately it forced its way out through one of the small orifices close to one of the anthers, and was found when caught to be smeared with the glutinous pollen. I then put the same bee into another labellum; and again it crawled out through one of the small orifices, always covered with pollen. I repeated the operation five times, always with the same result. I afterwards cut away the labellum, so as to examine the stigma, and found its whole surface covered with pollen. It should be noticed that an insect in making its escape, must first brush past the stigma and afterwards one of the anthers, so that it cannot leave pollen on the stigma, until being already smeared with pollen from one flower it enters another; and thus there will be a good chance of cross-fertilization between two distinct plants…. Thus the use of all parts of the flower, - namely, the inflected edges, or the polished inner sides of the labellum; the two orifices and their position close to the anthers and stigma, - the large size of the medial rudimentary stamen, - are rendered intelligible. An insect which enters the labellum is thus compelled to crawl out by one of the two narrow passages, on the sides of which the pollen-masses and stigma are placed."

These common orchids, which are not at all difficult to naturalize in a well-drained, shady spot in the garden, should be lifted with a good ball of earth and plenty of leaf-mould immediately after flowering. Here we can note little American Andrena bees unwittingly becoming the flower's slaves. Several species of exotic cypripediums are so common in the city florist's shops every one has an opportunity to study their marvelous structure.

The similar SMALL YELLOW LADY'S SLIPPER (C. parviflorum), a delicately fragrant orchid about half the size of its big sister, has a brighter yellow pouch, and occasionally its sepals and petals are purplish. As they usually grow in the same localities, and have the same blooming season, opportunities for comparison are not lacking. This fairer, sweeter, little orchid roams westward as far as the State of Washington.

YELLOW FRINGED ORCHIS
(Habenaria ciliaris) Orchid family

Flowers - Bright yellow or orange, borne in a showy, closely set, oblong spike, 3 to 6 in. long. The lip of each flower copiously fringed; the slender spur 1 to 1 1/2 in. long; similar to white fringed orchis (q.v.); and between the two, intermediate pale yellow hybrids may be found. Stem: Slender, leafy, 1 to 2 1/2 feet high. Leaves: Lance-shaped, clasping. Preferred Habitat - Moist meadows and sandy bogs. Flowering Season - July-August. Distribution - Vermont to Florida; Ontario to Texas.

Where this brilliant, beautiful orchid and its lovely white sister grow together in the bog - which cannot be through a very wide range, since one is common northward, where the other is rare, and vice versa - the yellow fringed orchis will be found blooming a few days later. In general structure the plants closely resemble each other. Their similar method of enforcing payment for a sip of nectar concealed in a tube so narrow and deep none but a sphinx moth or butterfly may drain it all (though large bumblebees occasionally get some too, from brimming nectaries) has been described (q.v.), to which the interested reader is referred. Both these orchids have their sticky discs projecting unusually far, as if raised on a pedicel - an arrangement which indicates that they "are to be stuck to the face or head of some nectar-sucking insect of appropriate size that visits the flowers," wrote Dr. Asa Gray over forty years ago. Various species of hawk moths, common in different parts of our area, of course have tongues of various lengths, and naturally every visitor does not receive his load of pollen on the same identical spot. At dusk, when sphinx moths begin their rounds, it will be noticed that the white and yellow flowers remain conspicuous long after blossoms of other colors have melted into the general darkness. Such flowers as cater to these moths, if they have fragrance, emit it then most strongly, as an additional attraction. Again, it will be noticed that few such flowers provide a strong projecting petal-platform for visitors to alight on; that would be superfluous, since sphinx moths suck while hovering over a tube, with their wings in exceedingly rapid motion, just like a hummingbird, for which the larger species are so often mistaken at twilight. This deep-hued orchid apparently attracts as many butterflies as sphinx moths, which show a predilection for the white species.

>From Ontario and the Mississippi eastward, and southward to the Gulf, the TUBERCLED or SMALL PALE GREEN ORCHIS (H. flava) lifts a spire of inconspicuous greenish-yellow flowers, more attractive to the eye of the structural botanist than to the aesthete. It blooms in moist places, as most orchids do, since water with which to manufacture nectar enough to fill their deep spurs is a prime necessity. Orchids have arrived at that pinnacle of achievement that it is impossible for them to fertilize themselves. More than that, some are absolutely sterile to their own pollen when it is applied to their stigmas artificially with insect aid, however, a single plant has produced over 1,000,700 seeds. No wonder, then, that, as a family, they have adopted the most marvelous blandishments and mechanism in the whole floral kingdom to secure the visits of that special insect to which each is adapted, and, having secured him, to compel him unwittingly to do their bidding. In the steaming tropical jungles, where vegetation is luxuriant to the point of suffocation, and where insect life swarms in mvriads undreamed of here, we can see the best of reasons for orchids mounting into trees and living on air to escape strangulation on the ground, and for donning larger and more gorgeous apparel to attract attention in the fierce competition for insect trade waged about them. Here, where the struggle for survival is incomparably easier, we have terrestrial orchids, small, and quietly clad, for the most part.

Having the gorgeous, exotic air plants of the hothouse in mind, this little tubercled orchis seems a very poor relation indeed. In June and July, about a week before the ragged orchis comes out, we may look for this small, fringeless sister. Its clasping leaves, which decrease in size as they ascend the stem (not to shut off the light and rain from the lower ones), are parallel-veined, elliptic, or, the higher ones, lance-shaped. A prominent tubercle, or palate, growing upward from the lip, almost conceals the entrance to the nectary. and makes a side approach necessary. Why? Usually an insect has free, straight access down the center of a flower's throat, but here he cannot have it. A slender tongue must be directed obliquely from above into the spur, and it will enter the discal groove as a thread enters the eye of a needle. By this arrangement the tongue must certainly come in contact with one of the sticky discs to which an elongated pollen gland is attached. The cement on the disc hardening even while the visitor sucks, the pollen gland is therefore drawn out, because firmly attached to his tongue. At first the pollen mass stands erect on the proboscis; but in the fraction of a moment which it takes a butterfly to flit to another blossom, it has bent forward automatically into the exact position required for it to come in contact with the sticky stigma of the next tubercled orchis entered, where it will be broken off. Now we understand the use of the palate. Butterfly collectors often take specimens with remnants of these pollen stumps stuck to their tongues. In his classical work "On the Fertilization of Orchids by Insects," Darwin tells of finding a mottled rustic butterfly whose proboscis was decorated with eleven pairs of pollen masses, taken from as many blossoms of the pyramidal orchis. Have these flowers no mercy on their long-suffering friends? A bee with some orchid pollen-stumps attached to its head was once sent to Mr. Frank Cheshire, the English expert who had just discovered some strange bee diseases. He was requested to name the malady that had caused so abnormal an outgrowth on the bee's forehead!

Often found growing in the same bog with the tubercled species is the RAGGED or FRINGED GREEN ORCHIS (H. lacera), so inconspicuous we often overlook it unawares. Examine one of the dingy, greenish-yellow flowers that are set along the stern in a spike to make all the show in the world possible, each with its three-parted, spreading lip finely and irregularly cut into thread-like fringe to hail the passing butterfly, and we shall see that it, too, has made ingenious provision against the draining of its spur by a visitor without proper pay for his entertainment. Even without the gay color that butterflies ever delight in, these flowers contain so much nectar in their spurs, neither butterflies nor large bumblebees are long in hunting them out. In swamps and wet woodland from Nova Scotia to Georgia, and westward to the Mississippi, the ragged orchis blooms in June or July.

LARGE YELLOW POND or WATER LILY; COW LILY; SPATTER-DOCK
(Nymphaea advena; Nupisar advena of Gray) Water-lily family

Flowers - Yellow or greenish outside, rarely purple tinged, round, depressed, 1 1/2 to 3 1/2 in. across. Sepals 6, unequal, concave, thick, fleshy; petals stamen-like, oblong, fleshy, short; stamens very numerous, in 5 to 7 rows; pistil compounded of many carpels, its stigmatic disc pale red or yellow, with 12 to 24 rays. Leaves: Floating, or some immersed, large, thick, sometimes a foot long, egg-shaped or oval, with a deep cleft at base, the lobes rounded. Preferred Habitat - Standing water, ponds, slow streams. Flowering Season - April-September. Distribution - Rocky Mountains eastward, south to the Gulf of Mexico, north to Nova Scotia.

Comparisons were ever odious. Because the yellow water lily has the misfortune to claim relationship with the sweet-scented white species (q.v.), must it never receive its just meed of praise? Hiawatha's canoe, let it be remembered,

"Floated on the river
Like a yellow leaf in autumn,
Like a yellow water-lily."

But even those who admire Longfellow's lines see no beauty in the golden flower-bowls floating among the large, lustrous, leathery leaves.

By assuming the functions of petals, the colored sepals advertise for insects. Beetles, which answer the first summons to a free lunch, crowd in as the sepals begin to spread. In the center the star-like disc, already sticky, is revealed, and on it any pollen they have carried with them from older flowers necessarily rubs off. At first, or while the stigma is freshly receptive to pollen, an insect cannot make his entrance except by crawling over this large, sticky plate. At this time, the anthers being closed, self-fertilization is impossible. A day or two later, after the pollen begins to ripen on countless anthers, the flower is so widely open that visitors have no cause to alight in the center; anyway, no harm could result if they did, cross-fertilization having been presumably accomplished. While beetles (especially Donacia) are ever abundant visitors, it is likely they do much more harm than good. So eagerly do they gnaw both petals and stamens, which look like loops of narrow yellow ribbon within the bowl of an older flower, that, although they must carry some pollen to younger flowers as they travel on, it is probable they destroy ten times more than their share. Flies transport pollen too. The smaller bees (Halictus and Andrena chiefly) find some nectar secreted on the outer faces of the stamen-like petals, which they mix with pollen to make their babies' bread.

The very beautiful native AMERICAN LOTUS (Nelumbo lutea), also known as WATER CHINKAPIN or WANKAPIN, found locally in Ontario, the Connecticut River, some lakes, slow streams, and ponds in New Jersey, southward to Florida, and westward to Michigan and Illinois, Indian Territory and Louisiana, displays its pale yellow flowers in July and August. They measure from four to ten inches across, and suggest a yellow form of the sweet-scented white water lily; but there are fewer petals, gradually passing into an indefinite number of stamens. The great round, ribbed leaves, smooth above, hairy beneath, may be raised high above the water, immersed or floating. Both leaf and flower stalks contain several large air canals. The flowers which are female when they expand far enough for a pollen-laden guest to crawl into the center, are afterward male, securing cross-fertilization by this means, just as the yellow pond lily does; only the small bees must content themselves here with pollen only - a diet that pleases the destructive beetles and the flies (Syrphidae) perfectly.

Japanese artists especially have taught us how much of the beauty of a Nelumbo we should lose if it ripened its decorative seed-vessel below the surface as the sweet-scented white water lily does. This flat-topped receptacle, held erect, has its little round nuts imbedded in pits in its surface, ready to be picked out by aquatic birds, and distributed by them in their wanderings. Both seeds and tubers are farinaceous and edible. In some places it is known the Indians introduced the plant for food. Professor Charles Goodyear has written an elaborate, plausible argument, illustrated, with many reproductions of sculpture, pottery, and mural painting in the civilized world of the ancients to prove that all decorative ornamental design has been evolved from the sacred Egyptian lotus (Nelumbo Nelumubo), still revered throughout the East (q.v.).

MARSH MARIGOLD; MEADOW-GOWAN; AMERICAN COWSLIP
(Caltha palustris) Crowfoot family'

Flowers - Bright, shining yellow, 1 to 1 1/2 in. across, a few in terminal and axillary groups. No petals; usually 5 (often more) oval, petal-like sepals; stamens numerous; many pistils (carpels) without styles. Stem: Stout, smooth, hollow, branching, 1 to 2 ft. high. Leaves: Mostly from root, rounded, broad, and heart-shaped at base, or kidney-shaped, upper ones almost sessile, lower ones on fleshy petioles. Preferred Habitat - Springy ground, low meadows, swamps, river banks, ditches. Flowering Season - April-June. Distribution - Carolina to Iowa, the Rocky Mountains, and very far north.

Not a true marigold, and even less a cowslip, it is by these names that this flower, which looks most like a buttercup, will continue to be called, in spite of the protests of scientific classifiers. Doubtless the first of these folk-names refers to its use in church festivals during the Middle Ages as one of the blossoms devoted to the Virgin Mary.

"And winking Mary-buds begin
To ope their golden eyes,"

sing the musicians in "Cymbeline." Whoever has seen the watery Avon meadows in April, yellow and twinkling with marsh marigolds when "the lark at heaven's gate sings," appreciates why the commentators incline to identify Shakespeare's Mary-buds with the Caltha of these and our own marshes.

Not for poet's rhapsodies, but for the more welcome hum of small bees and flies intent on breakfasting do these flowers open in the morning sunshine. Nectar secreted on the sides of each of the many carpels invites a conscientious bee all around the center, on which she should alight to truly benefit her entertainer. Honey bees may be seen sucking only enough nectar to aid them in storing pollen; bumblebees feasting for their own benefit, not their descendants'; little mining bees and quantities of flies also, although not many species are represented among the visitors, owing to the flower's early blooming season. Always conspicuous among the throng are the brilliant Syrphidae flies - gorgeous little creatures which show a fondness for blossoms as gaily colored as their own lustrous bodies. Indeed, these are the principal pollinators.

Some country people who boil the young plants declare these "greens" are as good as spinach. What sacrilege to reduce crisp, glossy, beautiful leaves like these to a slimy mess in a pot! The tender buds, often used in white sauce as a substitute for capers, probably do not give it the same piquancy where piquancy is surely most needed - on boiled mutton, said to be Queen Victoria's favorite dish. Hawked about the streets in tight bunches, the marsh-marigold blossoms - with half their yellow sepals already dropped - and the fragrant, pearly-pink arbutus are the most familiar spring wild flowers seen in Eastern cities.

COMMON MEADOW BUTTERCUP; TALL CROWFOOT; KINGCUPS; CUCKOO FLOWER; GOLDCUPS; BUTTER-FLOWERS; BLISTER-FLOWERS

(Ranunculus acris) Crowfoot family

Flowers - Bright, shining yellow, about 1 in. across, numerous, terminating long slender footstalks. Calyx of 5 spreading sepals; corolla of 5 petals; yellow stamens and carpels. Stem: Erect, branched above, hairy (sometimes nearly smooth), 2 to 3 feet tall, from fibrous roots. Leaves: In a tuft from the base, long petioled, of 3 to 7 divisions cleft into numerous lobes; stem leaves nearly sessile, distant, 3-parted. Preferred Habitat - Meadows, fields, roadsides, grassy places. Flowering Season - May-September. Distribution - Naturalized from Europe in Canada and the United States; most common North.

What youngster has not held these shining golden flowers under his chin to test his fondness for butter? Dandelions and marsh-marigolds may reflect their color in his clear skin too, but the buttercup is every child's favorite. When

"Cuckoo-buds of yellow hue
Do paint the meadows with delight,"

daisies, pink clover, and waving timothy bear them company here; not the "daisies pied," violets, and lady-smocks of Shakespeare's England. How incomparably beautiful are our own meadows in June! But the glitter of the buttercup, which is as nothing to the glitter of a gold dollar in the eyes of a practical farmer, fills him with wrath when this immigrant takes possession of his pastures. Cattle will not eat the acrid, caustic plant - a sufficient reason for most members of the Ranunculaceae to stoop to the low trick of secreting poisonous or bitter juices. Self-preservation leads a cousin, the garden monk's hood, even to murderous practices. Since children will put everything within reach into their mouths, they should be warned against biting the buttercup's stem and leaves, that are capable of raising blisters. "Beggars use the juice to produce sores upon their skin," says Mrs. Creevy. A designer might employ these exquisitely formed leaves far more profitably.

This and the bulbous buttercup, having so much else in common, have also the same visitors. "It is a remarkable fact," says Sir John Lubbock, "as Aristotle long ago mentioned, that in most cases bees confine themselves in each journey to a single species of plant; though in the case of some very nearly allied forms this is not so; for instance, it is stated on good authority (Muller) that Ranunculus acris, R. repens, and R. bulbosus are not distinguished by the bees, or at least are visited indifferently by them, as is also the case with two of the species of clover." From what we already know of the brilliant Syrphidae flies' fondness for equally brilliant colors, it is not surprising to find great numbers of them about the buttercups, with bees, wasps, and beetles - upwards of sixty species. Modern scientists believe that the habit of feeding on flowers has called out the color-sense of insects and the taste for bright colors, and that sexual selection has been guided by this taste. The most unscientific among us soon finds evidence on every hand that flowers and insects have developed together through mutual dependence.

By having its nourishment thriftily stored up underground all winter, the BULBOUS BUTTERCUP (R. bulbosus) is able to steal a march on its fibrous-rooted sister that must accumulate hers all spring; consequently it is first to flower, coming in early May, and lasting through June. It is a low and generally more hairy plant, but closely resembling the tall buttercup in most respects, and, like it, a naturalized European immigrant now thoroughly at home in fields and roadsides in most sections of the United States and Canada.

Much less common is the CREEPING BUTTERCUP (R. repens), which spreads by runners until it forms large patches in fields and roadsides, chiefly in the Eastern States. Its leaves, which are sometimes blotched, are divided into three parts, the terminal one, often all three, stalked. May-July.

First to bloom in the vicinity of New York (from March to May) is the HISPID BUTTERCUP (R. hispidus), densely hairy when young. The leaves, which are pinnately divided into from three to five leaflets, cleft or lobed, chiefly arise on long petioles from a cluster of thickened fibrous roots. The flower may be only half an inch or an inch and a half across. It is found in dry woods and thickets throughout the eastern half of the United States; whereas the much smaller flowered BRISTLY BUTTERCUP (R. Pennsylvanicus) shows a preference for low-lying meadows and wet, open ground through a wider, more westerly range. Its stout, hollow, leafy stem, beset with stiff hairs, discourages the tongues of grazing animals. June-August.

Commonest of the early buttercups is the TUFTED BUTTERCUP (R. fascicularis), a little plant seldom a foot high, found in the woods and on rocky hillsides from Texas and Manitoba, east to the Atlantic, flowering in April or May. The long-stalked leaves are divided into from three to five parts; the bright yellow flowers, with rather narrow, distant petals, measure about an inch across. They open sparingly, usually only one or two at a time on each plant, to favor pollination from another one.

Scattered patches of the SWAMP or MARSH BUTTERCUP (P. septentrionalis) brighten low, rich meadows also with their-large satiny yellow flowers, whose place in the botany even the untrained eye knows at sight. The smooth, spreading plant sometimes takes root at the joints of its branches and sends forth runners, but the stems mostly ascend. The large lower mottled leaves are raised well out of the wet, or above the grass, on long petioles. They have three divisions, each lobed and cleft. From Georgia and Kentucky far northward this buttercup blooms from April to July, opening only a few flowers at a time-a method which may make it less showy, but more certain to secure cross-pollination between distinct plants.

The YELLOW WATER BUTTERCUP or CROWFOOT (R. deiphinifolius; R. multifidus of Gray) found blooming in ponds through the summer months, certainly justifies the family name derived from rana = a frog. Many other members grow in marshes, it is true, but this ranunculus lives after the manner of its namesake, sometimes immersed, sometimes stranded on the muddy shore. Two types of leaves occur on the same stem. Their waving filaments, which make the immersed leaves look fringy, take every advantage of what little carbonic acid gas is dissolved under the surface. Moreover, they are better adapted to withstand the water's pressure and possible currents than solid blades would be. The floating leaves which loll upon the surface to take advantage of the air and sunlight, expand three, four, or five divisions, variously lobed. On this plant we see one set of leaves perfectly adapted to immersion, and another set to aerial existence. The stem, which may measure several feet in length, roots at the joints when it can. Range from the Mississippi and Ontario eastward to the Atlantic Ocean.

The WHITE WATER-CROWFOOT (Batrachium trichophyllum; Ranunculus aquatilis of Gray) has its fine thread-like leaves entirely submerged; but the flowers, like a whale, as the old conundrum put it, come to the surface to blow. The latter are small, white, or only yellow at the base, where each petal bears a spot or little pit that serves as a pathfinder to the flies. When the water rises unusually high, the blossoms never open, but remain submerged, and fertilize themselves. Seen underwater, the delicate leaves, which are little more than forked hairs, spread abroad in dainty patterns; lifted cut of the water these flaccid filaments utterly collapse. In ponds and shallow, slow streams, this common plant flowers from June to September almost throughout the Union, the British Possessions north of us, and in Europe and Asia.

The WATER PLANTAIN SPEARWORT (K. obtusiusculus; R. a/isrnaefoiius of Gray) flecks the marshes from June to August with its small golden flowers, which the merest novice knows must be kin to the buttercup. The smooth, hollow stem, especially thick at the base, likes to root from the lower joints. A peculiarity of the lance-shaped or oblong lance-shaped leaves is that the lower ones have petioles so broad where they clasp the stem that they appear to be long blades suddenly contracted just above their base.

BARBERRY; PEPPERIDGE-BUSH
(Berberis vulgaris) Barberry family

Flowers - Yellow, small, odor disagreeable, 6-parted, borne in drooping, many-flowered racemes from the leaf axils along arching twigs. Stem: A much branched, smooth, gray shrub, to 8 ft. tall, armed with sharp spines. Leaves: From the 3-pronged spines (thorns); oval or obovate, bristly edged. Fruit: Oblong, scarlet, acid berries. Preferred Habitat - Thickets; roadsides; dry or gravelly soil. Flowering Season - May-June. Distribution - Naturalized in New England and Middle States; less common in Canada and the West. Europe and Asia.

When the twigs of barberry bushes arch with the weight of clusters of beautiful bright berries in September, everyone must take notice of a shrub so decorative, which receives scant attention from us, however, when its insignificant little flowers are out. Yet these blossoms, small as they are, are up to a marvelous trick, quite as remarkable as the laurel's (q.v.) or the calopogon's (q.v.), to compel insects to do their bidding. Three of the six sepals, by their size and color, attend to the advertising, playing the part of a corolla; and partly by curving inward at the tip, partly by the drooping posture of the flower, help protect the stamens, pistil, and nectar glands within from rain. Did the flowers hang vertically, not obliquely, such curvature of the tips of sepals and petals would be unnecessary. Six stamens surround a pistil, but each of their six anthers, which are in reality little pollen boxes opening by trap-doors on either side, is tucked under the curving tip of a petal at whose base lie two orange-colored nectar glands. A small bee or fly enters the flower: what happens? To reach the nectar, he must probe between the bases of two exceedingly irritable stamens. The merest touch of a visitor's tongue against them releases two anthers, just as the nibbling mouse all unsuspectingly releases the wire from the hook of the wooden trap he is caught in. As the two stamens spring upward on being released, pollen instantly flies out of the trap-doors of the anther boxes on the bee, which suffers no greater penalty than being obliged to carry it to the stigma of another flower. So short are the stamens, it is improbable that a flower's pollen ever reaches its own stigma except through the occasional confused fumbling of a visitor. Usually he is so startled by the sudden shower of pollen that he flies away instantly.

In the barberry bushes, as in the gorse, when grown in dry, gravelly situations, we see many leaves and twigs modified into thorns to diminish the loss of water through evaporation by exposing too much leaf surface to the sun and air. That such spines protect the plants which bear them from the ravages of grazing cattle is, of course, an additional motive for their presence. Under cultivation, in well-watered garden soil - and how many charming varieties of barberries are cultivated - the thorny shrub loses much of its armor, putting forth many more leaves, in rosettes, along more numerous twigs, instead. Even the prickly-pear cactus might become mild as a lamb were it to forswear sandy deserts and live in marshes instead. Country people sometimes rob the birds of the acid berries to make preserves. The wood furnishes a yellow dye.

Curiously enough it is the EUROPEAN BARBERRY that is the common species here. The AMERICAN BARBERRY (B. Canadensis), a lower shrub, with dark reddish-brown twigs; its leaves more distantly toothed; its flowers, and consequently its berries, in smaller clusters, keeps almost exclusively to the woods in the Alleghany region and in the southwest, in spite of its specific name.

SPICE-BUSH; BENJAMIN-BUSH; WILD ALLSPICE; FEVER-BUSH
(Benzoin Benzoin; Lindera Benzoin of Gray) Laurel family

Flowers - Before the leaves, lemon yellow, fragrant, small, in clusters close to the slender, brittle twigs. Six petal-like sepals; sterile flowers with 9 stamens in 3 series; fertile flowers with a round ovary encircled by abortive stamens. Stem: A smooth shrub 4 to 20 ft. tall. Leaves: Alternate, entire, oval or elliptic, 2 to 5 in, long. Fruit: Oblong, red, berry-like drupes. Preferred Habitat - Moist woodlands, thickets, beside streams. Flowering Season - March-May. Distribution - Central New England, Ontario, and Michigan, southward to Carolina and Kansas.

Even before the scaly catkins on the alders become yellow, or the silvery velvet pussy willows expand to welcome the earliest bees that fly, this leafless bush breathes a faint spicy fragrance in the bleak gray woods. Its only rivals among the shrubbery, the service-berry and its twin sister the shad-bush, have scarcely had the temerity to burst into bloom when the little clusters of lemon-yellow flowers, cuddled close to the naked branches, give us our first delightful spring surprise. All the favor they ask of the few insects then flying is that they shall transfer the pollen from the sterile to the fertile flowers as a recompense for the early feast spread. Inasmuch as no single blossom contains both stamens and pistil, little wonder the flowers should woo with color and fragrance the guests on whose ministrations the continuance of the species absolutely depends. Later, when the leaves appear, we may know as soon as we crush them in the hand that the aromatic sassafras is next of kin. But ages before Linnaeus published "Species Plantarum" butterflies had discovered floral relationships.

Sharp eyes may have noticed how often the leaves on both the spice-bush and the sassafras tree are curled. Have you ever drawn apart the leaf edges and been startled by the large, fat green caterpillar, speckled with blue, whose two great black "eyes" stare up at you as he reposes in his comfortable nest - a cradle which also combines the advantages of a restaurant? This is the caterpillar of the common spice-bush swallow-tail butterfly (Papilio troilus), an exquisite, dark, velvety creature with pale greenish-blue markings on its hind wings. (See Dr. Holland's "Butterfly Book," Plate XLI.) The yellow stage of this caterpillar (which William Hamilton Gibson calls the "spice-bush bugaboo") indicates, he says, that "its period of transformation is close at hand. Selecting a suitable situation, it spins a tiny tuft of silk, into which it entangles its hindmost pair of feet, after which it forms a V-shaped loop about the front portion of its body, and hangs thus suspended, soon changing to a chrysalis of a pale wood color. These chrysalides commonly survive the winter, and in the following June the beautiful 'blue swallow-tail' will emerge, and may be seen suggestively fluttering and poising about the spice and sassafras bushes." After the eggs she lays on them hatch, the caterpillars live upon the leaves. Mrs. Starr Dana says the leaves were used as a substitute for tea during the Rebellion; and the powdered berries for allspice by housekeepers in Revolutionary days.

GREATER CELANDINE; SWALLOW-WORT
(Chelidonium majus) Poppy family

Flowers - Lustreless yellow, about 1/2 in. across, on slender pedicels, in a small umbel-like cluster. Sepals 2, soon falling; 4 petals, many yellow stamens, pistil prominent. Stem: Weak, to 2 ft. high, branching, slightly hairy, containing bright orange acrid juice. Leaves: Thin, 4 to 8 in. long, deeply cleft into 5 (usually) irregular oval lobes, the terminal one largest. Fruit: Smooth, slender, erect pods, 1 to 2 in, long, tipped with the persistent style. Preferred Habitat - Dry waste land, fields, roadsides, gardens, near dwellings. Flowering Season - April-September. Distribution - Naturalized from Europe in Eastern United States.

Not this weak invader of our roadsides, whose four yellow petals suggest one of the cross-bearing mustard tribe, but the pert little LESSER CELANDINE, PILEWORT, or FIGWORT BUTTERCUP (Ficaria Ficaria), one of the Crowfoot family, whose larger solitary satiny yellow flowers so commonly star European pastures, was Wordsworth's special delight - a tiny, turf-loving plant, about which much poetical association clusters. Having stolen passage across the Atlantic, it is now making itself at home about College Point, Long Island; on Staten Island; near Philadelphia, and maybe elsewhere. Doubtless it will one day overrun our fields, as so many other European immigrants have done.

The generic Greek name of the greater celandine, meaning a swallow, was given it because it begins to bloom when the first returning swallows are seen skimming over the water and freshly ploughed fields in a perfect ecstasy of flight, and continues in flower among its erect seed capsules until the first cool days of autumn kill the gnats and small winged insects not driven to cover. Then the swallows, dependent on such fare, must go to warmer climes where plenty still fly. Quaint old Gerarde claims that the swallow-wort was so called because "with this herbe the dams restore eye-sight to their young ones when their eye be put out" by swallows. Coles asserts "the swallow cureth her dim eyes with celandine."

There can be little satisfaction in picking a weed which droops immediately, poppy fashion, and whose saffron juice stains whatever it touches. A drop of this acrid fluid on the tip of the tongue is not soon forgotten. The luminous experiments of Darwin, Lubbock, Wallace, Muller, and Sprengel, among others, have proved that color in flowers exists for the purpose of attracting insects. But how about colored juices in the blood-roots' and poppies' stems, for example; the bright stalk of the pokeweed, the orange-yellow root of the carrot, the exquisite tints of autumn leaves, fungi, and seaweed? Besides the green color (chlorophyll), the most necessary of all ingredients to a plant are the lipochromes, which vary from yellow to red. These are most conspicuous when they displace the chlorophyll in autumn foliage. Then there are the anthocyans, ranging from magenta to blue and violet. These vary according to the amount of acid or alkali in the sap. Try the effect of immersing a blue morning glory in an acid solution, or a deep pink one in an alkaline solution. One theory to account for the presence of color is that it exists to screen the plant's protoplasm from light; that it has a physiological function with which insects have nothing whatever to do; and that by its presence the temperature is raised and the plant is protected from cold. Every one who has handled the colorless Indian pipe knows how cold and clammy it is.

The YELLOW or CELANDINE POPPY (Stylophorum diphyllum), with shining yellow flowers double the size of the greater celandine's, and similar pinnatifid leaves springing chiefly from the base, blooms even in March and through the spring in the Middle States and westward to Wisconsin and Missouri. Usually only one of the few terminal blossoms opens at a time, but in low, open woodlands it gleams like a miniature sun. Alas! that the glorious CALIFORNIA POPPY, so commonly grown in Eastern gardens (Eschscholtzia Californica), should confine itself to a limited range on the Pacific Coast. We have no true native poppies (Papaver) in America; such as are rarely to be seen in a wild state, have only locally escaped from cultivation.

GOLDEN CORYDALIS
(Capnoides aureum; Corydalis aurea of Gray) Poppy family

Flowers - Bright yellow, about 1/2 in. long, with a spur half the length of the tubular corolla; irregular, lipped; each upheld by a little bract, mostly at a horizontal; borne in a terminal, short raceme. Stem: Smooth, 6 to 14 in. high, branching. Leaves: Finely dissected, decom pound, petioled. Fruit: Sickle-shaped, drooping pods, wavy lumped, and tipped with the style. Preferred Habitat - Woods, rocky banks. Flowering Season - March-May. Distribution - Minnesota to Nova Scotia and Pennsylvania.

A dainty little plant, next of kin to the pink corydalis (q.v.).

BLACK MUSTARD
(Brassica nigra) Mustard family

Flowers - Bright yellow, fading pale, 1/4 to 1/2 in. across, 4-parted, in elongated racemes; quickly followed by narrow upright 4-sided pods about 1/2 in. long appressed against the stem. Stem: Erect, 2 to 7 ft. tall, branching. Leaves: Variously lobed and divided, finely toothed, the terminal lobe larger than the 2 to 4 side ones. Preferred Habitat - Roadsides, fields, neglected gardens. Flowering Season - June-November. Distribution - Common throughout our area; naturalized from Europe and Asia.

"The kingdom of heaven is like unto a grain of mustard seed, which a man took and sowed in his field which indeed is less than all seeds but when it is grown, it is greater than the herbs, and becometh a tree, so that the birds of the air come and lodge in the branches thereof."

Commentators differ as to which is the mustard of the parable - this common black mustard, or a rarer shrub-like tree (Salvadora Persica), with an equivalent Arabic name, a pungent odor, and a very small seed. Inasmuch as the mustard which is systematically planted for fodder by Old World farmers grows with the greatest luxuriance in Palestine, and the comparison between the size of its seed and the plant's great height was already proverbial in the East when Jesus used it, evidence strongly favors this wayside weed. Indeed, the late Dr. Royle, who endeavored to prove that it was the shrub that was referred to, finally found that it does not grow in Galilee.

Now, there are two species which furnish the most powerfully pungent condiment known to commerce; but the tiny dark brown seeds of the black mustard are sharper than the serpent's tooth, whereas the pale brown seeds of the WHITE MUSTARD, often mixed with them, are far more mild. The latter (Sinapis alba) is a similar, but more hairy, plant, with slightly larger yellow flowers. Its pods are constricted like a necklace between the seeds.

The coarse HEDGE MUSTARD (Sisymbrium officinale), with rigid, spreading branches, and spikes of tiny pale yellow flowers, quickly followed by awl-shaped pods that are closely appressed to the stem, abounds in waste places throughout our area. It blooms from May to November, like the next species.

Another common and most troublesome weed from Europe is the FIELD or CORN MUSTARD, CHARLOCK or FIELD KALE (Brassica arvensis; Sinapis arvensis of Gray) found in grain fields, gardens, rich waste lands, and rubbish heaps. The alternate leaves, which stand boldly out from the stem, are oval, coarsely saw-toothed, or the lower ones more irregular, and lobed at their bases, all rough to the touch, and conspicuously veined. The four-parted yellow flowers, measuring half an inch or more across, have six stamens (like the other members of this cross-bearing family), containing nectar at their bases. Two of them are shorter than the other four. Honey-bees, ever abundant, the brilliant Syrphidae flies which love yellow, and other small visitors after pollen and nectar, to obtain the latter insert their tongues between the stamens, and usually cross-fertilize the flowers. In stormy weather, when few insects fly, the anthers finally turn their pollen-covered tips upward; then, by a curvature of the tip of the stamens, they are brought in contact with the flower's own stigma; for it is obviously better that even self-fertilized seed should be set than none at all. (See Ladies'-smock.) "The birds of the air" may not lodge in the charlock's few and feeble branches; nevertheless they come seeking the mild seeds in the strongly nerved, smooth pods that spread in a loose raceme. Domestic pigeons eat the seeds greedily.

The highly intelligent honey-bee, which usually confines itself to one species of plant on its flights, apparently does not know the difference between the field mustard and the WILD RADISH, or JOINTED or WHITE CHARLOCK (Raphanus Raphanistrum); or, knowing it, does not care to make distinctions, for it may be seen visiting these similar flowers indiscriminately. At first the blossoms of the radish are yellow, but they quickly fade to white, and their purplish veins become more conspicuous. Rarely the flowers are all purplish. The entire plant is rough to the touch; the leaves, similar to those of the garden radish, are deeply cleft (lyrate-pinnatifid); the seed pods, which soon follow the flowers up the spike, are nearly cylindric when fresh, but become constricted between the seeds, as they dry, until each little pod looks like a section of a bead necklace.

The GARDEN RADISH of the market (R. sativus), occasionally escaped from cultivation, although credited to China, is entirely unknown in its native state. "It has long been held in high esteem," wrote Peter Henderson, "and before the Christian era a volume was written on this plant alone. The ancient Greeks, in offering their oblations to Apollo, presented turnips in lead, beets in silver, and radishes in vessels of beaten gold." Pliny describes a radish eaten in Rome as being so transparent one might see through the root. It was not until the sixteenth century that the plant was introduced into England. Gerarde mentions cultivating four varieties for Queen Elizabeth in Lord Burleigh's garden.

The YELLOW ROCKET, HERB OF ST. BARBARA, YELLOW BITTER-CRESS, WINTER- or ROCKET-CRESS (Barbarca Barbarea; B. vulgaris of Gray) sends up spikes of little flowers like a yellow sweet alyssum as early as April, and continues in bloom through June. Smooth pods about one inch long quickly follow. The thickish, shining, tufted leaves, very like the familiar WATER-CRESS (Roripa Nasturtium), were formerly even more commonly eaten as a salad. In rich but dry soil the plant flourishes from Virginia far northward, locally in the interior of the United States and on the Pacific Coast.

WITCH-HAZEL
(Hamamelis Virginiana) Witch-hazel family

Flowers - Yellow, fringy, clustered in the axils of branches. Calyx 4-parted; 4 very narrow curving petals about 34 in. long; 4 short stamens, also 4 that are scale-like; 2 styles. Stem: A tall, crooked shrub. Leaves: Broadly oval, thick, wavy-toothed, mostly fallen at flowering time. Fruit: Woody capsules maturing the next season and remaining with flowers of the succeeding year (Hama = together with; mela = fruit). Preferred Habitat - Moist woods or thickets near streams. Flowering Season - August-December. Distribution - Nova Scotia and Minnesota, southward to the Gulf States.

To find a stray. apple blossom among the fruit in autumn, or an occasional violet deceived by caressing Indian Summer into thinking another spring has come, surprises no one; but when the witch-hazel bursts into bloom for the first time in November, as if it were April, its leafless twigs conspicuous in the gray woods with their clusters of spidery pale yellow flowers, we cannot but wonder with Edward Rowland Sill:

"Has time grown sleepy at his post
And let the exiled Summer back?
Or is it her regretful ghost,
Or witchcraft of the almanac?"

Not to the blue gentian but to the witch-hazel should Bryant have addressed at least the first stanza of his familiar lines (See Fringed Gentian). The shrub doubtless gives the small bees and flies their last feast of the season in consideration of their services in transferring pollen from the staminate to the fertile flowers. Very slowly through the succeeding year the seeds within the woody capsules mature until, by the following autumn, when fresh flowers appear, they are ready to bombard the neighborhood after the violets' method, in the hope of landing in moist yielding soil far from the parent shrub to found a new colony. Just as a watermelon seed shoots from between the thumb and forefinger pinching it, so the large, bony, shining black, white-tipped witch-hazel seeds are discharged through the elastic rupture of their capsule whose walls pinch them out. To be suddenly hit in the face by such a missile brings no smile while the sting lasts. Witch-hazel twigs ripening indoors transform a peaceful living room into a defenseless target for light artillery practice.

Nowhere more than in the naming of wild flowers can we trace the homesickness of the early English colonists in America. Any plant even remotely resembling one they had known at home was given the dear familiar name. Now our witch-hazel, named for an English hazel tree of elm lineage, has similar leaves it is true, but likeness stops there; nevertheless, all the folklore clustered about that mystic tree has been imported here with the title. By the help of the hazel's divining-rod the location of hidden springs of water, precious ore, treasure, and thieves may be revealed, according to old superstition. Cornish miners, who live in a land so plentifully stored with tin and copper lodes they can have had little difficulty in locating seams of ore with or without a hazel rod, scarcely ever sink a shaft except by its direction.

The literature of Europe is filled with allusions to it. Swift wrote:

"They tell us something strange and odd
About a certain magic rod
That, bending down its top divines
Where'er the soil has hidden mines
Where there are none, it stands erect
Scorning to show the least respect."

A good story is told on Linnaeus in Baring-Gould's "Curious Myths of the Middle Ages": "When the great botanist was on one of his voyages, hearing his secretary highly extol the virtues of his divining-wand, he was willing to convince him of its insufficiency, and for that purpose concealed a purse of one hundred ducats under a ranunculus, which grew by itself in a meadow, and bid the secretary find it if he could. The wand discovered nothing, and Linnaeus's mark was soon trampled down by the company present, so that when he went to finish the experiment by fetching the gold himself, he was utterly at a loss where to find it. The man with the wand assisted him, and informed him that it could not lie in the way they were going, but quite the contrary so they pursued the direction of the wand, and actually dug out the gold. Linnaeus said that another such experiment would be sufficient to make a proselyte of him."

Many a well has been dug even in this land of liberty where our witch-hazel indicated; but here its kindly magic is directed chiefly through the soothing extract distilled from its juices.

FIVE-FINGER; COMMON CINQUEFOIL
(Potentilla Canadensis) Rose family

Flowers - Yellow, 1/4 to 1/2 in. across, growing singly on long peduncles from the leaf axils. Five petals longer than the 5 acute calyx lobes with 5 linear bracts between them; about 20 stamens; pistils numerous, forming a head. Stem: Spreading over ground by slender runners or ascending. Leaves: 5-fingered, the digitate, saw-edged leaflets (rarely 3 or 4) spreading from a common point, petioled; some in a tuft at base. Preferred Habitat - Dry fields, roadsides, hills, banks. Flowering Season - April-August. Distribution - Quebec to Georgia, and westward beyond the Mississippi.

Everyone crossing dry fields in the eastern United States and Canada at least must have trod on a carpet of cinquefoil (cinque = five, feuilles = leaves), and have noticed the bright little blossoms among the pretty foliage, possibly mistaking the plant for its cousin, the trefoliate barren strawberry (q.v.). Both have flowers like miniature wild yellow roses. During the Middle Ages, when misdirected zeal credited almost any plant with healing virtues for every ill that flesh is heir to, the cinquefoils were considered most potent remedies, hence their generic name.

The SHRUBBY CINQUEFOIL, or PRAIRIE WEED (P. fructicosa), becomes fairly troublesome in certain parts of its range, which extends from Greenland to Alaska, and southward to New Jersey, Arizona, and California; as well as over northern Europe and Asia. It is a bushy, much branched, and leafy shrub, six inches to four feet high), with bright yellow, five-parted flowers an inch across, more or less, either solitary or in cymes at the tips of the branches. They appear from June to September. The honeybee, alighting in the center of a blossom and turning around, passes its tongue over the entire nectar-bearing ring at the base of the stamens, then proceeding to another flower to do likewise, effects cross-fertilization regularly. On a sunny day the bright blossoms attract many visitors of the lower grade out after nectar and pollen, the beetles often devouring the anthers in their greed. The leaves on this cinquefoil are usually compounded of one terminal and four side leaflets that are narrowly oblong, an inch or less in length, and silky hairy. Sometimes there may be seven leaflets pinnately, not digitately, arranged. Although the shrubby cinquefoil prefers swamps and moist, rocky places to dwell in, it wisely adapts itself, as globe-trotters should, to whatever conditions it meets.

SILVERY or HOARY CINQUEFOIL (P. argentea), found in dry soil, blooming from May to September from Canada to Delaware, Indiana, Kansas, and Dakota, also in Europe and Asia, has yellow flowers only about a quarter of an inch across, but foliage of special beauty. From the tufted, branching, ascending stems, four to twelve inches long, the finely cleft, five-foliate leaves are spread on foot stems that diminish in size as they ascend, not to let the upper leaves shut off the light from the lower ones. These leaves are smooth and green above, silvery on the under side, with fine white hairs, adapted for protection from excessive sunlight and too rapid transpiration of precious moisture. They entirely conceal the sensitive epidermis from which they grow.

YELLOW AVENS; FIELD AVENS
(Geum strictum) Rose family

Flowers - Golden yellow, otherwise much resembling the lower growing white avens (q.v.). Preferred Habitat - Low ground, moist meadows, swamps. Flowering Season - June-August. Distribution - Pennsylvania, Missouri, and Arizona, far northward.

After the marsh marigolds have withdrawn their brightness from low-lying meadows, blossoms of yellow avens twinkle in their stead. In autumn the jointed, barbed styles, protruding from the seed clusters, steal a ride by the same successful method of travel to new colonizing ground adopted by burdocks, goose-grass, tick-trefoils (q.v.), agrimony, and a score of other "tramps of the vegetable world."

TALL or HAIRY AGRIMONY
(Agrimonia hirsuta; Eupatoria of Gray) Rose family

Flowers - Yellow, small, 5-parted, in narrow, spike-like racemes. Stem: Usua11y 3 to 4 ft. tall, sometimes less or more clothed, with long, soft hairs. Leaves: Large, thin, bright green, compounded of (mostly) 7 principal oblong, coarsely saw-edged leaflets, with pairs of tiny leaflets between. Preferred Habitat - Woods, thickets, edges of fields. Flowering Season - June-August. Distribution - North Carolina, westward to California, and far north.

Quite a different species, not found in this country, is the common European Agrimony - A. Eupatoria of Linnaeus - which figures so prominently in the writings of medieval herbalists as a cure-all. Slender spires of green fruit below and yellow flowers above curve and bend at the borders of woodlands here apparently for no better reason than to enjoy life. Very few insects visit them, owing to the absence of nectar - certainly not the highly specialized and intelligent "Humble-Bee," to whom Emerson addressed the lines:

"Succory to match the sky,
Columbine with horn of honey,
Scented fern and agrimony,
Clover, catch-fly, adder's-tongue,
And brier-roses, dwelt among."

It is true the bumblebee may dwell among almost any flowers, but he has decided preferences for such showy ones as have adapted themselves to please his love of certain colors (not yellow), or have secreted nectar so deeply hidden from the mob that his long tongue may find plenty preserved when he calls. Occasional visitors alighting on the agrimony for pollen may distribute some, but the little blossoms chiefly fertilize themselves. When crushed they give forth a faint, pleasant odor. Pretty, nodding seed urns, encircled with a rim of hooks, grapple the clothing of man or beast passing their way, in the hope of dropping off in a suitable place to found another colony.

SENSITIVE PEA; WILD or SMALL-FLOWERED SENSITIVE PLANT
(Cassia nictitans) Senna family

Flowers - Yellow, regular, 5-parted, about 1/4 in. across; 2 or 3 together in the axils. Stem: Weak, 6 to 15 in. tall, branching, leafy. Leaves: Alternate, sensitive, compounded of 12 to 44 small, narrowly oblong leaflets; a cup-shaped gland below lowest pair; stipules persistent. Fruit: A pod, an inch long or more, containing numerous seeds. Preferred Habitat - Dry fields, sandy wasteland, roadsides. Flowering Season - July-October. Distribution - New England westward to Indiana, south to Georgia and Texas.

How many of us ever pause to test the sensitiveness of this exquisite foliage that borders the roadsides, and in appearance is almost identical with the South American sensitive plant's, so commonly cultivated in hothouses here? Failing to see its fine little leaflets fold together instantly when brushed with the hand, as they do in the tropical species (Mimosa pudica), many pass on, concluding its title a misnomer. By simply touching the leaves, however roughly, only a tardy and slight movement follows. A sharp blow produces quicker effect, while if the whole plant be shaken by forcibly snapping the stem with the finger, all the leaves will be strongly affected; their sensitiveness being apparently more aroused by vibration through jarring than by contact with foreign bodies. The leaves, which ordinarily spread out flat, partly close in bright sunshine and "go to sleep" at night, not to expose their sensitive upper surfaces to fierce heat in the first case, and to cold by radiation in the second. "Lifeless things may be moved or acted on," says Asa Gray; "living beings move and act - plants less conspicuously, but no less really than animals. In sharing the mysterious gift of life they share some of its simpler powers."

The PARTRIDGE PEA or LARGE-FLOWERED SENSITIVE PLANT (C. Chamaecrista) likewise goes to sleep; the ten to fifteen pairs of leaflets which, with a terminal one, make up each pinnate leaf, slowly turning their outer edges uppermost after sunset, and overlapping as they flatten themselves against their common stem until the entire aspect of the plant is changed. By day the expanded foliage is feathery, fine, acacia-like; at night the bushy, branching, spreading plant, that measures only a foot or two high, appears to produce nothing but pods. These leaves respond slowly to vibration, just as the sensitive pea's do. In spite of their names, neither produces the butterfly-shaped (papilionaceous) blossom of true peas. The partridge pea bears from two to four showy flowers together, each measuring an inch or more across, on a slender pedicel from the axils. It fully expands only four of its five bright yellow petals; they are somewhat unequal in size, the upper ones, with touches of red at the base, as pathfinders, not, however, as nectar-guides, since no sweets are secreted here. Curiously enough, both right and left hand flowers are found upon the same plant; that is to say, the sickle-shaped pistil turns either to the right or the left. One lateral petal, instead of being flexible and spread like the rest, stands so stiffly erect and incurved that it commonly breaks on being bent back. Why? The pistil, it will be noticed, points away from the ten long black anthers. Obviously, then, the flower cannot fertilize itself. Its benefactors are bumblebee females and workers out after pollen. Cup-shaped nectaries ("extra nuptial") are situated on the upper side and near the base of the leaf stalks on these cassia plants, where they can have no direct influence on the fertilization of the blossoms. Apparently, they are free lunch-counters, kept open out of pure charity. Landing upon the long black anthers with pores in their tips to let out the pollen, the bumblebees "seize them between their mandibles, says Professor Robertson, "and stroke them downward with a sort of milking motion. The pollen…falls either directly upon the bee or upon the erect lateral petal which is pressed close against the bee's side. In this way the side of the bee which is next to the incurved petal receives the most pollen…. A bee visiting a left-hand flower receives pollen upon the right side, and then flying to a right-hand flower, strikes the same side against the stigma." When we find circular holes in these petals we may know the leaf-cutter or upholsterer bee (Megachile brevis) has been at work collecting roofs for her nurseries (see Hairy Ruellia). The partridge pea, which has a more westerly range than the sensitive pea's, extends it southward even to Bolivia. Game birds, migrants and rovers, which feed upon the seeds, have of course helped in their wider distribution. The plant blooms from July to September.

WILD or AMERICAN SENNA
(Cassia Marylandica) Senna family

Flowers - Yellow, about 3/4 in. broad, numerous, in short axillary clusters on the upper part of plant. Calyx of 5 oblong lobes; 5 petals, 3 forming an upper lip, 2 a lower one; 10 stamens of 3 different kinds; 1 pistil. Stem: 3 to 8 ft. high, little branched. Leaves: Alternate, pinnately compounded of 6 to 10 pairs of oblong leaflets. Fruit: A narrow, flat curving pod, 3 to 4 in. long. Preferred Habitat - Alluvial or moist, rich soil, swamps, roadsides. Flowering Season - July-August. Distribution - New England, westward to Nebraska, south to the Gulf States.

Whoever has seen certain Long Island roadsides bordered with wild senna, the brilliant flower clusters contrasted with the deep green of the beautiful foliage, knows that no effect produced by art along the drives of public park or private garden can match these country lanes in simple charm. Bumblebees, buzzing about the blossoms, may be observed "milking" the anthers just as they do those of the partridge pea. No red spots on any of these petals guide the visitors, as in the previous species, however; for do not the three small, dark stamens, which are reduced to mere scales, answer every purpose as pathfinders here? The stigma, turned sometimes to the right, sometimes to the left, strikes the bee on the side; the senna being what Delpino, the Italian botanist, calls a pleurotribe flower.

While leaves of certain African and East Indian species of senna are most valued for their medicinal properties, those of this plant are largely collected in the Middle and Southern States as a substitute. Caterpillars of several sulphur butterflies, which live exclusively on cassia foliage, appear to feel no evil effects from overdoses.

WILD INDIGO; YELLOW or INDIGO BROOM; HORSEFLY-WEED
(Baptisia tinctoria) Pea family

Flowers - Bright yellow, papilionaceous, about 1/2 in. long, on short pedicels, in numerous but few flowered terminal racemes. Calyx light green, 4 or 5-toothed; corolla of 5 oblong petals, the standard erect, the keel enclosing 10 incurved stamens and pistil. Stem: Smooth, branched, 2 to 4 ft. high. Leaves: Compounded of 3 ovate leaflets. Fruit: A many-seeded round or egg-shaped pod tipped with the awl-shaped style. Preferred Habitat - Dry, sandy soil. Flowering Season - June-September. Distribution - Maine and Minnesota to the Gulf States.

Dark grayish green, clover-like leaves, and small, bright yellow flowers growing in loose clusters at the ends of the branches of a bushy little plant, are so commonly met with they need little description. A relative, the true indigo-bearer, a native of Asia, once commonly grown in the Southern States when slavery made competition with Oriental labor possible, has locally escaped and become naturalized. But the false species, although, as Dr. Gray says, it yields "a poor sort of indigo," yields a most valuable medicine employed by the homeopathists in malarial fevers. The plant turns black in drying. As in the case of other papilionaceous blossoms, bees are the visitors best adapted to fertilize the flowers. When we see the little, sleepy, dusky-winged butterfly (Thanaos brizo) around the plant we may know she is there only to lay eggs, that the larvae and caterpillars may find their favorite food at hand on waking into life.

RATTLE-BOX
(Crotalaria sagittalis) Pea family

Flowers - Yellow, 1/2 in. long or less, usually only 2 or 3 on a long peduncle. Calyx 5-toothed, slightly 2-lipped; corolla papilionaceous. Stem: 3 to 10 in. high, weak, hairy. Leaves: Alternate, simple, oval to lance-shaped; stipules arrow-shaped above and running along stem. Fruit: An inflated oblong pod 1 in, long, blackish, seedy. Preferred Habitat - Dry, sandy, open situations. Flowering Season - June-September. Distribution - New England and Minnesota to the Gulf of Mexico.

These insignificant little yellow flowers attract scant notice from human observers accustomed to associate their generic name with some particularly beautiful relatives from the West Indies grown in hothouses here. But did not small bees alight on the keel and depress it, as in the lupine, next of kin (q.v.) there might be no seeds to rattle in the dark inflated pods that so delight children. (Krotalon = a castanet.)

YELLOW SWEET CLOVER; YELLOW MELILOT
(Melilotus officinalis) Pea family

Resembling the white sweet clover, except in color. (q.v.)

YELLOW or HOP CLOVER
(Trifotium agrarium) Pea family

Flowers - Yellow, scale-like, overlapping in a densely many-flowered oblong head about 1/2 in. long, becoming brown with age. Stem: Ascending, branched, 6 to 18 in. high. Leaves: 3-foliate, very finely toothed. Preferred Habitat - Waste places, fields, roadsides. Flowering Season - May-September. Distribution - Virginia to Iowa, and far northward.

What did the sulphur butterflies provide as food for their caterpillar babies before the commonest clovers came over from the Old World to possess the soil? Wherever a trifolium grows, there one is sure to see

"gallow-yellow butterflies,
Like blooms of lorn primroses blowing loose,
when autumn winds arise."

The BLACKSEED HOP CLOVER, BLACK or HOP MEDIC (Medicago lupulina), with even smaller, bright yellow oblong heads which turn black when ripe, lies on the ground, its branches spreading where they leave the root. A native of Europe and Asia, it is now distributed as a common weed throughout our area, for there is scarcely a month in the year when it does not bloom and set seed. It is still another of the many plants known as the shamrock.

YELLOW WOOD-SORREL; LADY'S SORREL
(Oxalis stricta) Wood-sorrel family

Flowers - Golden, fragrant, in long peduncled, small, terminal groups. Calyx of 5 sepals; corolla of 5 petals, usually reddish at base; stamens, 10; 1 pistil with 5 styles; followed by slender pods. Stem: Pale, erect, 3 to 12 in. high, the sap sour. Leaves: Palmately compound, of 3 heart-shaped, clover-like leaflets on long petioles. Preferred Habitat - Open woodlands, waste or cultivated soil, roadsides. Flowering Season - April-October. Distribution - Nova Scotia and Dakota westward to the Gulf of Mexico.

An extremely common little weed, whose peculiarly sensitive leaves children delight to set in motion by rubbing, or to chew for the sour juice. Concerning the night "sleep" of wood-sorrel leaves and the two kinds of flowers these plants bear, see the white and violet wood-sorrels.

WILD or SLENDER YELLOW FLAX
(Linum Virginianum) Flax family

Flowers - Yellow, about 1/3 in. across, each from a leaf axil,
scattered along the slender branches. Sepals, 5; 5 petals, 5
stamens. Stem: 1 to 2 ft. high, branching, leafy. Leaves.
Alternate, seated on the stem; small, oblong, or lance-shaped, 1
nerved.
Preferred Habitat - Dry woodlands and borders; shady places.
Flowering Season - June-August.
Distribution - New England to Georgia.

Certainly in the Atlantic States this is the commonest of its slender, dainty tribe; but in bogs and swamps farther southward and westward to Texas the RIDGED YELLOW FLAX (L. striatum), with leaves arranged opposite each other up to the branches and an angled stem so sticky it "adheres to paper in which it is dried," takes its place.

"Blue were her eyes as the fairy flax,"

wrote Longfellow, as if blue flax were a familiar sight on this side of the Atlantic. The charming little European plant (L. usitatissimum), which has furnished the fiber for linen and the oily seeds for poultices from time immemorial, is only a fugitive from cultivation here. Unhappily, it is rarely met with along the roadsides and railways as it struggles to gain a foothold in our waste places. Possibly Longfellow had in mind the blue toad flax (q.v.).

JEWEL-WEED; SPOTTED TOUCH-ME-NOT: SILVER CAP; WILD BALSAM: LADY'S
EARDROPS; SNAP WEED; WILD LADY'S SLIPPER
(Impatiens biflora; I. fulva of Gray) Jewel-weed family

Flowers - Orange yellow, spotted with reddish-brown, irregular, 1 in. long or less, horizontal, 2 to 4 pendent by slender footstalks on a long peduncle from leaf axils. Sepals, 3, colored; 1 large, sac-shaped, contracted into a slender incurved spur and 2-toothed at apex; 2 other sepals small. Petals, 3; 2 of them 2-cleft into dissimilar lobes; 5 short stamens, 1 pistil. Stem: 2 to 5 ft. high, smooth, branched, colored, succulent. Leaves: Alternate, thin, pale beneath, ovate, coarsely toothed, petioled. Fruit: An oblong capsule, its 5 valves opening elastically to expel the seeds. Preferred Habitat - Beside streams, ponds, ditches; moist ground. Flowering Season - July-October. Distribution - Nova Scotia to Oregon, south to Missouri and Florida.

These exquisite, bright flowers, hanging at a horizontal, like jewels from a lady's ear, may be responsible for the plant's folk name; but whoever is abroad early on a dewy morning, or after a shower, and finds notched edges of the drooping leaves hung with scintillating gems, dancing, sparkling in the sunshine, sees still another reason for naming this the jewel-weed. In a brook, pond, spring, or wayside trough, which can never be far from its haunts, dip a spray of the plant to transform the leaves into glistening silver. They shed water much as the nasturtium's do.

When the tiny ruby-throated hummingbird flashes northward out of the tropics to spend the summer, where can he hope to find nectar so deeply secreted that not even the long-tongued bumblebee may rob him of it all? Beyond the bird's bill his tongue can be run out and around curves no other creature can reach. Now the early blooming columbine, its slender cornucopias brimming with sweets, welcomes the messenger whose needle-like bill will carry pollen from flower to flower; presently the coral honeysuckle and the scarlet painted-cup attract him by wearing his favorite color; next the jewel-weed hangs horns of plenty to lure his eye; and the trumpet vine and cardinal flower continue to feed him successively in Nature's garden; albeit cannas, nasturtiums, salvia, gladioli, and such deep, irregular showy flowers in men's flower beds sometimes lure him away. These are bird flowers dependent in the main on the ruby-throat, which is not to say that insects never enter them, for they do; only they are not the visitors catered to. Watch the big, velvety bumblebee approach a roomy jewel-weed blossom and nearly disappear within. The large bunch of united stamens, suspended directly over the entrance, bears copious white pollen. So much comes off on his back that after visiting a flower or two he becomes annoyed; clings to a leaf with his fore legs while he thoroughly brushes his back and wings with his middle and hind pairs, and then collects the sticky grains into a wad on his feet which he presently kicks off with disgust to the ground. Examine a jewel-weed blossom to see that the clumsy bumblebee's pollen-laden back is not so likely to come in contact with the short five-parted stigma concealed beneath the stamens, as a hummingbird's slender bill that is thrust obliquely into the spur while he hovers above.

But, as if the plant had not sufficient confidence in its visitors to rely exclusively on them for help in continuing the lovely species, it bears also cleistogamous blossoms that never open - economical products without petals, which ripen abundant self-fertilized seed (see white wood sorrel). It is calculated that each jewel-weed blossom produces about two hundred and fifty pollen grains; yet each is by no means able to produce seed in spite of its prodigality. Nevertheless, enough cross-fertilized seed is set to save the species from the degeneracy that follows close inbreeding among plants as well as animals. In England, where this jewel-weed is rapidly becoming naturalized, Darwin recorded there are twenty plants producing cleistogamous flowers to one having showy blossoms which, even when produced, seldom set seed. What more likely, since hummingbirds are confined to the New World? Therefore why should the plant waste its energy on a product useless in England? It can never attain perfection there until hummingbirds are imported, as bumblebees had to be into Australia before the farmers could harvest seed from their clover fields (see red clover).

Familiar as we may be with the nervous little seedpods of the touch-me-not, which children ever love to pop and see the seeds fly, as they do from balsam pods in grandmother's garden, they still startle with the suddenness of their volley. Touch the delicate hair-trigger at the end of a capsule, and the lightning response of the flying seeds makes one jump. They sometimes land four feet away. At this rate of progress a year, and with the other odds against which all plants have to contend, how many generations must it take to fringe even one mill pond with jewel-weed; yet this is rapid transit indeed compared with many of Nature's processes. The plant is a conspicuous sufferer from the dodder (q.v.).

The PALE TOUCH-ME-NOT (I. aurea; I. pallida of Gray) most abundant northward, a larger, stouter species found in similar situations, but with paler yellow flowers only sparingly dotted if at all, has its broader sac-shaped sepal abruptly contracted into a short, notched, but not incurved spur. It shares its sister's popular names.

VELVET LEAF; INDIAN MALLOW; AMERICAN JUTE
(Abutilon Abulilon; A. Avicennae of Gray) Mallow family

Flowers - Deep yellow, 1/2 to 3/4 in. broad, 5-parted, regular, solitary on stout peduncles from the leaf axils. Stem: 3 to 6 ft. high, velvety, branched. Leaves: Soft velvety, heart-shaped, the lobes rounded, long petioled. Fruit: In a head about 1 in. across, 12 to 15 erect hairy carpels, with spreading sharp beaks. Preferred Habitat - Escaped from cultivation to waste sandy loam, fields, roadsides. Flowering Season - August-October. Distribution - Common or frequent, except at the extreme North.

There was a time, not many years ago, when this now common and often troublesome weed was imported from India and tenderly cultivated in flower gardens. In the Orient it and allied species are grown for their fiber, which is utilized for cordage and cloth; but the equally valuable plant now running wild here has yet to furnish American men with a profitable industry. Although the blossom is next of kin to the veiny Chinese bell-flower, or striped abutilon, so common in greenhouses, its appearance is quite different.

ST. ANDREW'S CROSS
(Ascyrum hypericoides; A. Crux-Andreae of Gray) St.
John's-wort family

Flowers - Yellow, 1/2 to 3/4 in. across, terminal and from the leaf axils. Calyx of 4 sepals in 2 pairs; 4 narrow, oblong petals; stamens numerous; 2 styles. Stem: Much branched and spreading from base, 5 to 10 in. high, leafy. Leaves: Opposite, oblong, small, seated on stem. Preferred Habitat - Dry, sandy soil; pine barrens. Flowering Season - July-August. Distribution - Nantucket Island (Mass.), westward to Illinois, south to Florida and Texas.

Because the four pale yellow petals of this flower approach each other in pairs, suggesting a cross with equals arms, the plant was given its name by Linnaeus in 1753. ST. PETER'S-WORT (A. stans), a similar plant, found in the same localities, in bloom at the same time, has larger flowers in small clusters at the tips only of its upright branches.

COMMON ST. JOHN'S-WORT
(Hypericum perforatum) St. John's-wort family

Flowers - Bright yellow, 1 in. across or less, several or many in terminal clusters. Calyx of 5 lance-shaped sepals; 5 petals dotted with black; numerous stamens in 3 sets 3 styles. Stem: to 2 ft. high, erect, much branched. Leaves: Small, opposite, oblong, more or less black-dotted. Preferred Habitat - Fields, waste lands, roadsides. Flowering Season - June-September. Distribution - Throughout our area, except the extreme North; Europe, and Asia.

"Gathered upon a Friday, in the hour of Jupiter when he comes to his operation, so gathered, or borne, or hung upon the neck, it mightily helps to drive away all phantastical spirits." These are the blossoms which have been hung in the windows of European peasants for ages on St. John's eve, to avert the evil eye and the spells of the spirits of darkness. "Devil chaser" its Italian name signifies. To cure demoniacs, to ward off destruction by lightning, to reveal the presence of witches, and to expose their nefarious practices, are some of the virtues ascribed to this plant, which superstitious farmers have spared from the scythe and encouraged to grow near their houses until it has become, even in this land of liberty, a troublesome weed at times. "The flower gets its name," says F. Schuyler Mathews, "from the superstition that on St. John's day, the 24th of June, the dew which fell on the plant the evening before was efficacious in preserving the eyes from disease. So the plant was collected, dipped in oil, and thus transformed into a balm for every wound." Here it is a naturalized, not a native, immigrant. A blooming plant, usually with many sterile shoots about its base, has an unkempt, untidy look; the seed capsules and the brown petals of withered flowers remaining among the bright yellow buds through a long season. No nectar is secreted by the St. John's-worts, therefore only pollen collectors visit them regularly, and occasionally cross-fertilize the blossoms, which are best adapted, however, to pollinate themselves.

The SHRUBBY ST. JOHN'S-WORT (H. prolificum) bears yellow blossoms, about half an inch across, which are provided with stamens so numerous, the many flowered terminal clusters have a soft, feathery effect. In the axils of the oblong, opposite leaves are tufts of smaller ones, the stout stems being often concealed under a wealth of foliage. Sandy or rocky places from New Jersey southward best suit this low, dense, diffusely branched shrub which blooms prolifically from July to September.

Farther north, and westward to Iowa, the GREAT or GIANT ST. JOHN'S-WORT (H. Ascyron) brightens the banks of streams at midsummer with large blossoms, each on a long footstalk in a few-flowered cluster.

LONG-BRANCHED FROST-WEED; FROST-FLOWER; FROST-WORT; CANADIAN
ROCK-ROSE
(Helianthemum Canadense) Rock-rose family

Flowers - Solitary, or rarely 2; about 1 in. across, 5-parted, with showy yellow petals; the 5 unequal sepals hairy. Also abundant small flowers lacking petals, produced from the axils later. Stem: Erect, 3 in. to 2 ft. high; at first simple, later with elongated branches. Leaves: Alternate, oblong, almost seated on stem. Preferred Habitat - Dry fields, sandy or rocky soil. Flowering Season - Petal-bearing flowers, May-July. Distribution - New England to the Carolinas, westward to Wisconsin and Kentucky.

Only for a day, and that must be a bright sunny one, does the solitary frost-flower expand its delicate yellow petals. On the next, after pollen has been brought to it by insect messengers and its own carried away, the now useless petal advertisements fall, and the numerous stamens, inserted upon the receptacle with them, also drop off, leaving the club-shaped pistil to develop with the ovary into a rounded, ovoid, three-valved capsule. Notice how flat the stamens lie upon the petals to keep safely out of reach of the stigma. Another flower, exactly like the first, now expands, and the bloom continues for weeks. Why does only one blossom open at a time? Because the whole aim of the showy flowers is to set cross-fertilized seed, and when only one at a time appears, pollination not only between distinct blossoms but between distinct plants insures the healthiest, most vigorous offspring - a wise precaution against degeneracy, in view of the quantities of self-fertilized seed that will be set late in summer by the tiny apetalous flowers that never open (see white wood sorrel). Surely two kinds of blossoms should be enough for any species; but why call this the frost-flower when its bloom is ended by autumn? Only the witch-hazel may be said to flower for the first time after frost. When the stubble in the dry fields is white some cold November morning, comparatively few notice the ice crystals, like specks of glistening quartz, at the base of the stems of this plant. The similar HOARY FROST-WEED (H. majus), whose showy flowers appear in clusters at the hoary stein's summit, in June and July, also bears them. Often this ice formation assumes exquisite feathery, whimsical forms, bursting the bark asunder where an astonishing quantity of sap gushes forth and freezes. Indeed, so much sap sometimes goes to the making of this crystal flower, that it would seem as if an extra reservoir in the soil must pump some up to supply it with its large fantastic corolla.

BEACH or FALSE HEATHER; POVERTY GRASS
(Hudsonia tomentosa) Rock-rose family

Flowers - Bright yellow, small, about 1/4 in. across, numerous,
closely ascending the upper part of the heath-like branches.
Sepals 5, unequal; 5 petals; stamens, 9 to 18. Stem: 4 to 8 in.
tall, tufted, densely branched and matted, hoary hairy, pale.
Leaves: Overlapping like scales, very small.
Preferred Habitat - Sands of the seashore, pine barrens, beaches
of rivers and lakes.
Flowering Season - May-July.
Distribution - New Brunswick to Maryland, west to Lake of the
Woods.

Like the showy flowers of the frost-weed, these minute ones open in the sunshine only, and then but for a single day. Nevertheless, the hoary, heath-like little shrub, by growing in large colonies and keeping up a succession of bright bloom, tinges the sand dunes back of the beach with charming color that artists delight to paint in the foreground of their marine pictures.

YELLOW VIOLETS
(Viola) Violet family

Fine hairs on the erect, leafy, usually single stem of the DOWNY YELLOW VIOLET (V. pubescens), whose dark veined, bright yellow petals gleam in dry woods in April and May, easily distinguish it from the SMOOTH YELLOW VIOLET (V. scabriuscula), formerly considered a mere variety in spite of its being an earlier bloomer, a lover of moisture, and well equipped with basal leaves at flowering time, which the downy species is not. Moreover, it bears a paler blossom, more coarsely dentate leaves, often decidedly taper-pointed, and usually several stems together.

Our other common yellow species, the ROUND-LEAVED VIOLET (V. rotundifolia), lifts smaller, pale, brown-veined, and bearded blossoms above a tuffet of broad, shining leaves close to the ground. The veins on the petals serve as pathfinders to the nectary for the bee, and the beard as footholds, while she probes the inverted blossoms. Such violets as have their side petals bearded are most frequently visited by small greenish mason bees (Osmia), with collecting brushes on their abdomen that receive the pollen as it falls. Abundant cleistogamous flowers (see blue violets and white wood sorrel) are borne on the runners late in the season. Bryant, whose botanical lore did not always keep step with his Muse, wrote of the yellow violet as the first spring flower, because he found it "by the snowbank's edges cold," one April day, when the hepaticas about his home at Roslyn, Long Island, had doubtless been in bloom a month.

"Of all her train the hands of Spring
First plant thee in the watery mould,"

he wrote, regardless of the fact that the round-leaved violet's preferences are for dry, wooded, or rocky hillsides. Muller believed that all violets were originally yellow, not white, after they evoluted from the green stage.

EASTERN CACTUS; PRICKLY PEAR; INDIAN FIG
(Opuntia Opuntia; 0. vulgaris of Gray) Cactus family

Flowers -Yellow, sometimes reddish at center, 2 to 3 in. across, solitary, mostly seated at the side of joints. Calyx tube not prolonged beyond ovary, its numerous lobes spreading. Petals numerous; stamens very numerous; ovary cylindric; the style longer than stamens, and with several stigmas. Stem: Prostrate or ascending, fleshy, juicy, branching, the thick, flattened joints oblong or rounded, 2 to 5 in. long. Leaves: Tiny, awl-shaped, dotting the joints, but usually falling early; tufts of yellowish bristles at their base. Plant unarmed, or with few solitary stout spines. Fruit: Pear-shaped, pulpy, red, nearly smooth, 1 in. long or over, edible. Preferred Habitat - Sandy or dry or rocky places. Flowering Season - June-August. Distribution - Massachusetts to Florida.

Upwards of one hundred and fifty species of Opuntia, which elect to grow in parching sands, beneath a scorching sun, often prostrate on baking hot rocks, on glaring plains, beaches, and deserts, from Massachusetts to Peru - for all are natives of the New World - show so marvelous an adaptation to environment in each instance that no group of plants is more interesting to the botanist, more decorative in form and color from an artistic standpoint, more distinctively characteristic. Plants choosing such habitats as they have adopted, usually in tropical or semi-tropical regions, had to resort to various expedients to save loss of water through transpiration and evaporation. Now, as leaves are the natural outlets for moisture thrown off by any plant, manifestly the first thing to do was either to reduce the number of branches and leaves, or to modify them into sharp spines (not surface prickles like the rose's); to cultivate a low habit of growth, not to expose unnecessary surface to sun and air; to thicken the skin until little moisture could evaporate through the leathery coat; and, finally, to utilize the material thus saved in developing stems so large, fleshy, and juicy that they should become wells in a desert, with powers of sustenance great enough to support the plant through its fiery trials. A common expedient of plants in dry situations, even at the north, is to modify their leaves into spines, as the gorse and the barberry, for example, have done. That such an armor also serves to protect them against the ravages of grazing animals is an additional advantage, of course; but not their sole motive in wearing it. Popular to destruction would the cool juices of the cacti be in thirsty lands, if only they might be obtained without painful and often poisonous scratches. Given moist soil and greater humidity of atmosphere to grow in, spiny plants at once show a tendency to grow taller, to branch and become leafy. A covering of hairs which reflect the light, thus diminishing the amount that might reach the juicy interior area, has likewise been employed by many cacti, among other denizens of dry soil.

In this common prickly pear cactus of the Atlantic seaboard, where the air is laden with moisture from the ocean, few or no spines are produced; and dotted over the surface of its branching, fleshy, flattened joints we find tiny, awl-shaped leaves, whereas foliage is entirely wanting in the densely prickly, rounded, solid, unbranched, hairy cacti of the southwestern deserts, and the arid plains of Mexico.

In sunshine the beautiful yellow blossom of our prickly pear expands to welcome the bees, folding up its petals again for several successive nights. William Hamilton Gibson says it "encloses its buzzing visitor in a golden bower, from which he must emerge at the roof as dusty as a miller," only to enter another blossom and leave some pollen on its numerous stigmas.

But the cochineal, not the bee, is forever associated with cacti in the popular mind. Indeed, several species are extensively grown on plantations, known as Nopaleries, which furnish food to countless trillions of these tiny insects. Like its relative the aphis of rose bushes (see wild roses), the cochineal fastens itself to a cactus plant by its sucking tube, to live on the juices. The males are winged, and only the female, which yields the valuable dye, sticks tight to the plant. Three crops of insects a year are harvested on a Mexican plantation. After three months' sucking, the females are brushed off, dried in ovens, and sold for about two thousand dollars a ton. The annual yield of Mexico amounting to many thousands of tons, it is no wonder the cactus plant, which furnishes so valuable an industry, should appear on the coat-of-arms of the Mexican republic. Some cacti are planted for hedges, the fruit of others furnishes a refreshing drink in tropical climates, the juices are used as a water color, and to dye candies - in short, this genus Opuntia and allied clans have great commercial value.

The WESTERN PRICKLY PEAR (0. humifusa; O. Rafnesquii of Gray) - a variable species ranging from Minnesota to Texas, is similar to the preceding, but bears a larger flower, and longer, more rounded, deeper green joints, beset with not numerous spines, scattered chiefly near their margins. A few deflexed spines in a cluster leave the surface where a tiny awl-shaped leaf and a tuft of reddish brown hairs are likewise usually found.

EVENING-PRIMROSE; NIGHT WILLOW-HERB (Onagra biennis; Qenothera biennis of Gray) Evening-primrose family

Flowers - Yellow, fragrant, opening at evening, 1 to 2 in. across, borne in terminal leafy-bracted spikes. Calyx tube slender, elongated, gradually enlarged at throat, the 4-pointed lobes bent backward; corolla of 4 spreading petals; 8 stamens; 1 pistil; the stigma 4-cleft. Stem: Erect, wand-like, or branched, to 1 to 5 ft. tall, rarely higher, leafy. Leaves: Alternate, lance-shaped, mostly seated on stem, entire, or obscurely toothed. Preferred Habitat - Roadsides, dry fields, thickets, fence-corners. Flowering Season - June-October. Distribution - Labrador to the Gulf of Mexico, west to the Rocky Mountains.

Like a ballroom beauty, the evening primrose has a jaded, bedraggled appearance by day when we meet it by the dusty roadside, its erect buds, fading flowers from last night's revelry, wilted ones of previous dissipations, and hairy oblong capsules, all crowded together among the willow-like leaves at the top of the rank growing plant. But at sunset a bud begins to expand its delicate petals slowly, timidly - not suddenly and with a pop, as the evening primrose of the garden does.

Now, its fragrance, that has been only faintly perceptible during the day, becomes increasingly powerful. Why these blandishments at such an hour? Because at dusk, when sphinx moths, large and small, begin to fly (see Jamestown weed), the primrose's special benefactors are abroad. All these moths, whose length of tongue has kept pace with the development of the tubes of certain white and yellow flowers dependent on their ministrations, find such glowing like miniature moons for their special benefit, when blossoms of other hues have melted into the deepening darkness. If such have fragrance, they prepare to shed it now. Nectar is secreted in tubes so deep and slender that none but the moths' long tongues can drain the last drop. An exquisite, little, rose-pink twilight flyer, his wings bordered with yellow, flutters in ecstasy above the evening primrose's freshly opened flowers, transferring in his rapid flight some of their abundant, sticky pollen that hangs like a necklace from the outstretched filaments. By day one may occasionally find a little fellow asleep in a wilted blossom, which serves him as a tent, under whose flaps the brightest bird eye rarely detects a dinner. After a single night's dissipation the corolla wilts, hangs a while, then drops from the maturing capsule as if severed with a sharp knife. Few flowers, sometimes only one opens on a spike on a given evening - a plan to increase the chances of cross-fertilization between distinct plants; but there is a very long succession of bloom. If a flower has not been pollenized during the night it remains open a while in the morning. Bumblebees now hurry in, and an occasional hummingbird takes a sip of nectar. Toward the end of summer, when so much seed has been set that the flower can afford to be generous, it distinctly changes its habit and keeps open house all day.

During our winter walks we shall see close against the ground the rosettes of year-old evening primrose plants - exquisitely symmetrical, complex stars from whose center the flower stalks of another summer will arise.

Floriform sunshine bursts forth from roadsides, fields, and prairies when the COMMON SUNDROPS (Kneiffia fructicosa; formerly Qenothera fructicosa) - is in flower. It is first cousin to the similar evening primrose of taller, ranker growth. Often only one blossom on a stalk expands at a time, to increase the chances of cross-fertilization between distinct plants; but where colonies grow it is a conspicuous acquaintance, for its large, bright yellow corollas remain open all day. Bumblebees with their long tongues, and some butterflies, drain the deeply hidden nectar; smaller visitors get some only when it wells up high in the tube. As the stigma surpasses the anthers, self-fertilization is impossible unless an insect blunders by alighting elsewhere than on the lower side, where the stigma is purposely turned to be rubbed against his pollen-laden ventral surface when he settles on a blossom. Unable to reach the nectar, mining and leaf-cutter bees, wasps, flower flies, and beetles visit it for the abundant pollen; and the common little white cabbage butterfly (Pieris protodice) sucks here constantly. The capsules of the sundrops are somewhat club-shaped and four-winged, angled above, with four intervening ribs between. Range from Nova Scotia to Georgia, west beyond the Mississippi.

A similar, but smaller, diurnal species (K. pumilla), likewise found blooming in dry soil from June to August, has a more westerly range North and South.

WILD OR FIELD PARSNIP; MADNEP; TANK
(Pastinaca sativa) Carrot family

Flowers - Dull or greenish yellow, small, without involucre or involucels; borne in 7 to 15 rayed umbels, 2 to 6 in. across. Stem: 2 to 5 ft. tall, stout, smooth, branching, grooved, from a long, conic, fleshy, strong-scented root. Leaves: Compounded (pinnately), of several pairs of oval, lobed, or cut, sharply toothed leaflets; the petioled lower leaves often 1 1/2 ft. long. Preferred Habitat - Waste places, roadsides, fields. Flowering Season - June-September. Distribution - Common throughout nearly all parts of the United States and Canada. Europe.

Men are not the only creatures who feed upon such of the umbel-bearing plants as are innocent - parsnips, celery, parsley, carrots, caraway, and fennel, among others; and even those which contain properties that are poisonous to highly organized men and beasts, afford harmless food for insects. Pliny says that parsnips, which were cultivated beyond the Rhine in the days of Tiberius, were brought to Rome annually to please the emperor's exacting palate; yet this same plant, which has overrun two continents, in its wild state (when its leaves are a paler yellowish green than under cultivation) often proves poisonous. A strongly acrid juice in the very tough stem causes intelligent cattle to let it alone - precisely the object desired. But caterpillars of certain swallow-tail butterflies, particularly of the common eastern swallow-tail (Papilio asterias), may be taken on it - the same greenish, black-banded, and yellow-dotted fat "worm" found on parsnips, fennel, and parsley in the kitchen garden. Insects understood plant relationships ages before Linnaeus defined them. When we see this dark, velvety butterfly, marked with yellow, hovering above the wild parsnip, we may know she is there only to lay eggs that her larvae may eat their way to maturity on this favorite food store. After the flat, oval, shining seeds with their conspicuous oil tubes are set in the spreading umbels, the strong, vigorous plant loses nothing of its decorative charm.

>From April to June the lower-growing EARLY or GOLDEN MEADOW PARSNIP (Zizia aurea) spreads its clearer yellow umbels above moist fields, meadows, and swamps from New Brunswick and Dakota to the Gulf of Mexico. Its leaves are twice or thrice compounded of oblong, pointed, saw-edged, but not lobed leaflets.

The HAIRY-JOINTED MEADOW PARSNIP (Thaspium barbinode), another early bloomer, with pale-yellow flowers, most common in the Mississippi basin, may always be distinguished by the little tufts of hair at the joints of the stem, the compound leaves, and often on the rays of the umbels.

A yellow variety of the PURPLE MEADOW PARSNIP, which is popularly known as GOLDEN ALEXANDERS (T. trifoliatum var. aureum), confines itself chiefly to woodlands. The leaves are compounded of three leaflets, longer and more lance-shaped in outline than those of other yellow species.

FOUR-LEAVED or WHORLED LOOSESTRIFE; CROSSWORT
(Lysimachia quadrifolia) Primrose family

Flowers - Yellow, streaked with dark red, 1/2 in. across or less; each on a thread-like, spreading footstem from a leaf axil. Calyx, 5 to 7 parted; corolla of 5 to 7 spreading lobes, and as many stamens inserted on the throat; 1 pistil. Stem: Slender, erect, to 3 ft. tall, leafy. Leaves: In whorls of 4 (rarely in 3's to 7's), lance-shaped or oblong, entire, black dotted. Preferred Habitat - Open woodland, thickets, roadsides, moist, sandy soil. Flowering Season - June-August. Distribution - Georgia and Illinois, north to New Brunswick.

Medieval herbalists usually recorded anything that "Plinie saieth" with profoundest respect; not always so, quaint old Parkinson. Speaking of the common (vulgaris), wild loosestrife of Europe, a rather stout, downy species with terminal clusters of good-sized, yellow flowers, that was once cultivated in our Eastern States, and has sparingly escaped from gardens, he thus refers to the reputation given it by the Roman naturalist: "It is believed to take away strife, or debate between ye beasts, not onely those that are yoked together, but even those that are wild also, by making them tame and quiet…if it be either put about their yokes or their necks," significantly adding, "which how true, I leave to them shall try and find it soe." Our slender, symmetrical, common loosestrife, with its whorls of leaves and little star-shaped blossoms on thread-like pedicels at regular intervals up the stem, is not even distantly related to the wonderful purple loosestrife (q.v.).

Another common, lower-growing species, the BULB-BEARING LOOSESTRIFE (L. terrestris; L. stricta of Gray) - blooming from July to September, lifts a terminal, elongated raceme of even smaller, slender-pedicelled, yellow flowers streaked or dotted with reddish; and in the axils of its abundant, opposite, lance-shaped, black-dotted leaves, long bulblets, that are in reality suppressed branches, are usually borne after the flowering season. Occasionally no flowers are produced, only these strange bulblets. In this state Linnaeus mistook the plant for a terrestrial mistletoe. This species shows a decided preference for swamps, moist thickets, and ditches throughout a range which extends from Manitoba and Arkansas to the Atlantic Ocean.

MONEYWORT, or CREEPING LOOSESTRIFE (L. Nummularia), a native of Great Britain, which has long been a favorite vine in American hanging baskets and urns, when kept in moist soil, suspended from a veranda, will produce prolific shoots two or three feet in length, hanging down on all sides. Pairs of yellow, dark-spotted, five-lobed flowers grow from the axils of the opposite leaves from June to August. One often finds it running wild in moist soil beyond the pale of old gardens from Pennsylvania and Indiana northward into Canada. Slight encouragement in starting runaways would easily induce the hardy little evergreen to be as common here as it is in England.

The LANCE-LEAVED LOOSESTRIFE (Steironema lanceolatum), most common in the West and South, although it is by no means rare in the northeastern States, produces either single blossoms or few-flowered, spreading, axillary clusters on slender peduncles, each unspotted, yellow corolla half an inch across or over; the petal edges as if gnawed by the finest of teeth; the pointed calyx segments showing between them. Sterile stamens in addition to the fertile ones characterize this clan. In moist soil it blooms from June to August. It is a strange fact that female bees of the genus Macropis have never been taken on plants outside the loosestrife connection. Here there appears to be the closest interdependence between flower and insect. Even in Germany, Muller found them by far the most abundant visitors, "diligently sweeping the flowers (L. vulgaris) and piling large masses of moistened pollen on their hind legs." He inclined to believe that such blossoms in this group as have spots or streaks on their petals - pathfinders for insect visitors - are largely dependent on them, and cannot easily fertilize themselves; whereas the unmarked blossoms, growing in such situations as are less favorable to insect visits, are regularly self-fertile.

BUTTERFLY-WEED; PLEURISY-ROOT; ORANGE-ROOT; ORANGE MILKWEED
(Asclepias tuberosa) Milkweed family

Flowers - Bright reddish orange, in many-flowered, terminal clusters, each flower similar in structure to the common milkweed (q.v.). Stem: Erect, 1 to 2 ft. tall, hairy, leafy, milky juice scanty. Leaves: Usually all alternate, lance-shaped, seated on stem. Fruit: A pair of erect, hoary pods, 2 to 5 in. long, at least containing silky plumed seeds. Preferred Habitat - Dry or sandy fields, hills, roadsides. Flowering Season - June-September. Distribution - Maine and Ontario to Arizona, south to the Gulf of Mexico.

Intensely brilliant clusters of this the most ornamental of all native milkweeds set dry fields ablaze with color. Above them butterflies hover, float, alight, sip, and sail away - the great, dark, velvety, pipe-vine swallow-tail (Papilio philenor), its green-shaded hind wings marked with little white half moons; the yellow and brown, common, Eastern swallow-tail (P. asterias), that we saw about the wild parsnip and other members of the carrot family the exquisite, large, spice-bush swallow-tail, whose bugaboo caterpillar startled us when we unrolled a leaf of its favorite food supply (see spice-bush); the small, common, white, cabbage butterfly (Pieris protodice); the even more common little sulphur butterflies, inseparable from clover fields and mud puddles; the painted lady that follows thistles around the globe; the regal fritillary (Argynnis idalia), its black and fulvous wings marked with silver crescents, a gorgeous creature developed from the black and orange caterpillar that prowls at night among violet plants; the great spangled fritillary of similar habit; the bright fulvous and black pearl crescent butterfly (Phyciodes tharos), its small wings usually seen hovering about the asters; the little grayish-brown, coral hair-streak (Thecla titus), and the bronze copper (Chrysophanus thoe), whose caterpillar feeds on sorrel (Rumex); the delicate, tailed blue butterfly (Lycaena comyntas), with a wing expansion of only an inch from tip to tip; all these visitors duplicated again and again - these and several others that either escaped the net before they were named, or could not be run down, were seen one bright midsummer day along a Long Island roadside bordered with butterfly weed. Most abundant of all was still another species, the splendid monarch (Anosia plexippus), the most familiar representative of the tribe of milkweed butterflies (see common milkweed). Swarms of this enormously prolific species are believed to migrate to the Gulf States, and beyond at the approach of cold weather, as regularly as the birds, traveling in numbers so vast that the naked trees on which they pause to rest appear to be still decked with autumnal foliage. This milkweed butterfly "is a great migrant," says Dr. Holland, "and within quite recent years, with Yankee instinct, has crossed the Pacific, probably on merchant vessels, the chrysalids being possibly concealed in bales of hay, and has found lodgment in Australia where it has greatly multiplied in the warmer parts of the Island Continent, and has thence spread northward and westward, until in its migrations it has reached Java and Sumatra, and long ago took possession of the Philippines…. It has established a more or less precarious foothold for itself in southern England. It is well established at the Cape Verde Islands, and in a short time we may expect to hear of it as having taken possession of the Continent of Africa, in which the family of plants upon which the caterpillars feed is well represented."

Surely here is a butterfly flower if ever there was one, and such are rare. Very few are adapted to tongues so long and slender that the bumblebee cannot help himself to their nectar; but one almost never sees him about the butterfly-weed. While other bees, a few wasps, and even the ruby-throated hummingbird, which ever delights in flowers with a suspicion of red about them, sometimes visit these bright clusters, it is to the ever-present butterfly that their marvelous structure is manifestly adapted. Only visitors long of limb can easily remove the pollinia, which are usually found dangling from the hairs of their legs. We may be sure that after generously feeding its guests, the flower does not allow many to depart without rendering an equivalent service. The method of compelling visitors to withdraw pollen-masses from one blossom and deposit them in another - an amazing process - has been already described under the common milkweed. Lacking the quantity of sticky milky juice which protects that plant from crawling pilferers, the butterfly-weed suffers outrageous robberies from black ants. The hairs on its stem, not sufficient to form a stockade against them, serve only as a screen to reflect light lest too much may penetrate to the interior juices. We learned, in studying the prickly pear cactus, how necessary it is for plants living in dry soil to guard against the escape of their precious moisture.

Transplanted from Nature's garden into our own, into what Thoreau termed "that meager assemblage of curiosities, that poor apology for Nature and Art which I call my front yard," clumps of butterfly-weed give the place real splendor and interest. It is said the Indians used the tuberous root of this plant for various maladies, although they could scarcely have known that because of the alleged healing properties of the genus Linnaeus dedicated it to Aesculapius, of whose name Asclepias is a Latinized corruption.

HORSE-BALM; CITRONELLA; RICH-WEED; STONE-ROOT; HORSE-WEED
(Collinsonia Canadensis) Mint family

Flowers - Light yellowish, lemon-scented, about 1/2 in. long, mostly opposite, in numerous spreading racemes, forming long, loose terminal clusters. Calyx bell-shaped, 2-lipped, upper lip 3-toothed, lower lip 2-cleft; corolla 5-lobed, 4 lobes nearly equal, the fifth much larger, fringed; stamens protruding, 2 anther-bearing; 1 long style, the stigma forked. Preferred Habitat - Rich, moist woods. Flowering Season - July-October. Distribution - New England, Ontario, and Wisconsin, south to Florida and Kansas.

Now that we have come to read the faces of flowers much as their insect friends must have done for countless ages, we suspect at a glance that the strong-scented horse-balm, with its profusion of lemon-colored, irregular little blossoms, is up to some ingenious trick. The lower lip, out of all proportion to the rest of the corolla, flaunting its enticing fringes; the long stamens protruding from some flowers, and only the long style from others on the same plant, excite our curiosity. Where many fragrant clumps grow in cool, shady woods at midsummer, is an excellent place to rest a while and satisfy it. Presently a bumblebee, attracted by the odor from afar, alights on the fringed platform too weak to hold him. Dropping downward, he snatches the filaments of the two long stamens to save himself; and, as he does so, pollen jarred out of their anther sacs falls on his thorax at the juncture of his wings. Hanging beneath the flower a second, he sips its nectar and is off. Many bees, large and small, go through a similar performance. Now the young, newly opened flowers have the forked stigmas of the long style only protruding at this stage, the miniature stamens being still curled within the tube. Obviously a pollen-dusted bee coming to one of these young flowers must rub off some of the vitalizing dust on the sticky fork that purposely impedes his entrance at the precise spot necessary. Notice that after a flower's stamens protrude in the second stage of its development the fork is turned far to one side to get out of harm's way - self-fertilization being an abomination. It was the lamented William Hamilton Gibson who first called attention to the horse-balm's ingenious scheme to prevent it.

VIRGINIA GROUND CHERRY
(Physalis Virginiana; P. Pennsylvanica of Gray) Potato family

Flowers - Sulphur or greenish yellow, with 5 dark purplish dots, 1 in. across or less, solitary from the leaf axils. Calyx 5-toothed, much inflated in fruit; corolla open bell-shaped, the edge 5-cleft; 5 stamens, the anthers yellow, style slender, 2-cleft. Stem: l 1/2 to 3 ft. tall, erect, more or less hairy or glandular, branched, from a thick rootstock. Leaves: Ovate to lanceolate, tapering at both ends or wedge-shaped, often yellowish green, entire or sparingly wavy-toothed. Fruit: An inflated, 5-angled capsule, sunken at the base, loosely surrounding the edible reddish berry. Preferred Habitat - Open ground; rich, dry pastures; hillsides. Flowering Season - July-September Distribution - New York to Manitoba, south to the Gulf States.

A common plant, so variable, however, that the earlier botanists thought it must be several distinct species, lanceolata among others. A glance within shows that the open flower is not so generous as its spreading form would seem to indicate, for tufts of dense hairs at each side of grooves where nectar is secreted, conceal it from the mob, and, with the thickened filaments, almost close the throat. Doubtless these hairs also serve as footholds for the welcome bee clinging to its pendent host. The dark spots are pathfinders. One anther maturing after another, a visitor must make several trips to secure all the pollen, and if she is already dusted from another blossom, nine chances out of ten she will first leave some of the vitalizing dust on the stigma poked forward to receive it before collecting more. Professor Robertson says that all the ground cherries near his home in Illinois are remarkable for their close mutual relation with two bees of the genus Colletes. So far as is known, the insignificant little greenish or purplish bell-shaped flowers of the Alum-root (Heuchera Americana), with protruding orange anthers, are the only other ones to furnish these females with pollen for their babies' bread. Slender racemes of this species are found blooming in dry or rocky woods from the Mississippi eastward, from May to July, by which time the ground cherry is ready to provide for the bee's wants. The similar Philadelphia species was formerly cultivated for its "strawberry tomato." Many birds which feast on all this highly attractive fruit disperse the numerous kidney-shaped seeds.

GREAT MULLEIN; VELVET or FLANNEL PLANT; MULLEIN DOCK; AARON'S ROD
(Verbascum Thapsus) Figwort family

Flowers - Yellow, 1 in. across or less, seated around a thick, dense, elongated spike. Calyx 5-parted; corolla of 5 rounded lobes; 5 anther-bearing stamens, the 3 upper ones short, woolly; 1 pistil. Stem: Stout, 2 to 7 ft. tall, densely woolly, with branched hairs. Leaves: Thick, pale green, velvety-hairy, oblong, in a rosette on the ground; others alternate, strongly clasping the stem. Preferred Habitat - Dry fields, banks, stony waste land. Flowering Season - June-September. Distribution - Minnesota and Kansas, eastward to Nova Scotia and Florida. Europe.

Leaving the fluffy thistle-down he has been kindly scattering to the four winds, the goldfinch spreads his wings for a brief undulating flight, singing in waves also as he goes to where tall, thick-set mullein stalks stand like sentinels above the stony pasture. Here companies of the exquisite little black and yellow minstrels delight to congregate with their somber families and feast on the seeds that rapidly follow the erratic flowers up the gradually lengthening spikes.

Delpino long ago pointed out that the blossom is best adapted to pollen-collecting bees, which, alighting on the two long, protruding stamens, rub off pollen on their undersides while clinging for support to the wool on the three shorter stamens, whose anthers supply their needs. As a bee settles on another flower, the stigma is calculated to touch the pollen on his under side before he gets dusted with more; thus cross-pollination is effected. Three stamens furnish a visitor with food, two others clap pollen on him. Numerous flies assist in removing the pollen, too.

"I have come three thousand miles to see the mullein cultivated in a garden, and christened the velvet plant," says John Burroughs in "An October Abroad." But even in England it grows wild, and much more abundantly in Southern Europe, while its specific name is said to have been given it because it was so common in the neighborhood of Thapsus; but whether the place of that name in Africa, or the Sicilian town mentioned by Ovid and Virgil, is not certain. Strange that Europeans should labor under the erroneous impression that this mullein is native to America, whereas here it is only an immigrant from their own land. Rapidly taking its course of empire westward from our seaports into which the seeds smuggled their passage among the ballast, it is now more common in the Eastern States, perhaps, than any native. Forty or more folk-names have been applied to it, mostly in allusion to its alleged curative powers, its use for candlewick and funeral torches in the Middle Ages. The generic title, first used by Pliny, is thought to be a corruption of Barbascum = with beards, in allusion to the hairy filaments, or, as some think, to the leaves.

Of what use is this felt-like covering to the plant? The importance of protecting the delicate, sensitive, active cells from intense light, draught, or cold, have led various plants to various practices; none more common, however, than to develop hairs on the epidermis of their leaves, sometimes only enough to give it a downy appearance, sometimes to coat it with felt, as in this case, where the hairs branch and interlace. Fierce sunlight in the exposed, dry situations where the mullein grows; prolonged drought, which often occurs at flowering season, when the perpetuation of the species is at stake; and the intense cold which the exquisite rosettes formed by year-old plants must endure through a winter before they can send up a flower-stalk the second spring - these trials the well-screened, juicy, warm plant has successfully surmounted through its coat of felt. Hummingbirds have been detected gathering the hairs to line their tiny nests. The light, strong stalk makes almost as good a cane as bamboo, especially when the root end, in running under a stone, forms a crooked handle. Pale country beauties rub their cheeks with the velvety leaves to make them rosy.

MOTH MULLEIN
(Verbascum Blattaria) Figwort family

Flowers - Yellow, or frequently white, 5-parted, about 1 in. broad, marked with brown; borne on spreading pedicles in a long, loose raceme; all the filaments with violet hairs; 1 protruding pistil. Stem: Erect, slender, simple, about 2 ft. high, sometimes less, or much taller. Leaves: Seldom present at flowering time; oblong to ovate, toothed, mostly sessile, smooth. Preferred Habitat - Dry, open wasteland; roadsides, fields. Flowering Season - June-November. Distribution - Naturalized from Europe and Asia, more or less common throughout the United States and Canada.

Quite different from its heavy and sluggish looking sister is this sprightly, slender, fragile-flowered mullein. "Said to repel the cockroach (Blatta). hence the name Blattaria; frequented by moths, hence moth mullein." (Britton and Brown's "Flora.") Are the latter frequent visitors? Surely there is nothing here to a moth's liking. New England women used to pack this plant among woolen garments in summer to keep out the tiny clothes moths. The flower, whose two long stamens and pistil protrude as from the great mullein's blossom, and whose filaments are tufted with violet wool footholds - unnecessary provisions for moths, which rarely alight on any flower, but suck with their wings in motion - are cross-fertilized by pollen-collecting bees and flies as described in the account of the great mullein.

"Of beautiful weeds quite a long list might be made without including any of the so-called wild flowers," says John Burroughs. "A favorite of mine is the little moth mullein that blooms along the highway, and about the fields, and maybe upon the edge of the lawn." Even in winter, when the slender stem, set with round brown seed-vessels, rises above the snow, the plant is pleasing to the human eye, as it is to that of hungry birds.

BUTTER-AND-EGGS; YELLOW TOAD-FLAX; EGGS-AND-BACON; FLAXWEED;
BRIDEWEED
(Linaria Linaria; L. vulgaris of Gray) Figwort family

Flowers - Light canary yellow and orange, 1 in. long or over, irregular, borne in terminal, leafy-bracted spikes. Corolla spurred at the base, 2-lipped, the upper lip erect, 2-lobed; the lower lip spreading, 3-lobed, its base an orange-colored palate closing the throat; 4 stamens in pairs within; 1 pistil. Stem: 1 to 3 ft. tall, slender, leafy. Leaves: Pale, grass-like. Preferred Habitat - Wasteland, roadsides, banks, fields. Flowering Season - June-October. Distribution - Nebraska and Manitoba, eastward to Virginia and Nova Scotia. Europe and Asia.

An immigrant from Europe, this plebeian perennial, meekly content with waste places, is rapidly inheriting the earth. Its beautiful spikes of butter-colored cornucopias, apparently holding the yolk of a diminutive Spanish egg, emit a cheesy odor, suggesting a close dairy. Perhaps half the charm of the plant consists in the pale bluish-green grass-like leaves with a bloom on the surface, which are put forth so abundantly from the sterile shoots. (See blue toad-flax.)

Guided by the orange palate pathfinder to where the curious, puzzling flower opens, the big velvety bumblebee alights, his weight depressing the lower lip until a comfortable entrance through the gaping mouth is offered him. In he goes, and his long tongue readily reaches the nectar in the deep spur, while his back brushes off pollen from the stamens in his way overhead. Then he backs out, and the gaping mouth springs shut after him - for the linaria is akin to the snapdragon in the garden. As its stamens are of two lengths, the flower is able to fertilize itself in stormy weather, insects failing to transfer its pollen. To drain ten of these spurs a minute is no difficult task for the bumblebee. But how slowly, painfully, the little lightweight hive-bees and leaf-cutters squeeze in between the tight lips. An occasional butterfly inserts its long, thin tongue, and, without transferring a grain of pollen for the flower, robs it of sweets clearly intended for the bumblebee alone. Even when ants - the worst pilferers extant - succeed in entering, they cannot reach the nectar, owing to the hairy stockade bordering the groove where it runs. Beetles, out for pollen, also occasionally steal an entrance, if nothing more. Grazing cattle let the plant alone to ripen seed in peace, for it secretes disagreeable juices in its cells - juices that were once mixed with milk by farmers' wives to poison flies.

DOWNY FALSE FOXGLOVE
(Dasystoma flava; Gerardia flava of Gray) Figwort family

Flowers - Pale yellow, 1 1/2 to 2 in. long; in showy, terminal, leafy-bracted racemes. Calyx bell-shaped, 5-toothed; corolla funnel form, the 5 lobes spreading, smooth outside, woolly within; 4 stamens in pairs, woolly; 1 pistil. Stem: Grayish, downy, erect, usually simple, 2 to 4 ft. tall. Leaves: Opposite, lower ones oblong in outline, more or less irregularly lobed and toothed; upper ones small, entire. Preferred Habitat - Gravelly or sandy soil, dry thickets, open woods. Flowering Season - July-August Distribution - "Eastern Massachusetts to Ontario and Wisconsin, south to southern New York, Georgia, and Mississippi." (Britton and Brown.)

In the vegetable kingdom, as in the spiritual, all degrees of backsliding sinners may be found, each branded with a mark of infamy according to its deserts. We have seen how the dodder vine lost both leaf and roots after it consented to live wholly by theft of its hardworking host's juices through suckers that penetrate to the vitals; how the Indian pipe's blanched face tells the story of guilt perpetrated under cover of darkness, in the soil below; how the broom-rape and beech-drops lost their honest green color; and, finally, the foxgloves show us plants with their faces so newly turned toward the path of perdition, their larceny so petty, that only the expert in criminal botany cases condemns them. Like its cousins the gerardias (q.v.), the downy false foxglove is only a partial parasite, attaching its roots by disks or suckers to the roots of white oak or witch hazel (q.v.); not only that, but, quite as frequently, groping blindly in the dark, it fastens suckers on its own roots, actually thieving from itself! It is this piratical tendency which makes transplanting of foxgloves into our gardens so very difficult; even when lifted with plenty of their beloved vegetable mould. The term false foxglove, it should be explained, is by no means one of reproach for dishonesty; it was applied simply to distinguish this group of plants from the true foxgloves cultivated, not wild, here, which yield digitalis to the doctors.

But if these foxgloves live at others' expense, there are creatures which in turn prey upon them. Caterpillars of a peacock butterfly, known as the buckeye (Junonia coenia), with eye-like spots on its tawny, reddish-gray wings, divide their unwelcome attentions between various species of plantain, the snapdragon in the garden, gerardias, and foxgloves.

The SMOOTH FALSE FOXGLOVE (D. Virginica; G. quercifolia of Gray) - which delights in rich woods, moist or dry, bears similar, but slightly larger, blossoms on a smooth, usually branched, and taller stem, whose lower leaves especially are much cleft (pinnatifid). This species is commoner South and West, blooming from July to September. All the foxgloves elevate their sticky stigmas to the mouth of their tubes, that the pollen-dusted bumblebee may leave some of the vitalizing dust brought from another flower on its surface before she turns upside down and enters in this unusual fashion to receive a fresh supply on her way to the nectar in the base of the tube. Her pressure against the pointed anther-tips causes the light, dry pollen to sift out; on the removal of her pressure the gaping chinks close to save it from small bees and flies. It falls out, therefore, only when the bee is in the right position to receive it for export to another foxglove's stigma. Hairy footholds on anthers and filaments are provided lest the bee fall while reversed and sifting out the pollen.

The FERN-LEAVED or LOUSEWORT FALSE FOXGLOVE (D. pedicularia; G. pedicularia of Gray) - a very leafy species found in dry woods and thickets from the Mississippi and Ontario eastward to the Atlantic, north and south, has all its leaves once or twice pinnatifid, the lobes much cut and toothed. It is a rather sticky, hairy, slender, and much branched plant, growing from one to four feet tall; the broad, trumpet-shaped, yellow flower, which is sticky outside, measures an inch or an inch and a half long, and is sometimes almost as wide across. "The most abundant visitor, and the one for which the flower is most perfectly adapted," says Professor Robertson, "is Bombus Americanorum. This bee always turns head downwards on entering the flower. When it enters, or backs out, the basal joints of its legs strike the tips of the anther-cells, when the pollen falls out. I had often wondered why this bee turned upside down to enter the flower…. I discovered that the form of the flower requires it. The modification which requires the bees to reverse is associated with the peculiar mode of pollen discharge. Smaller bumblebees and some other bees which never or rarely try to suck hang under the anthers and work out the pollen by striking the trigger-like awns. They reverse of their own accord, since they are so small they are not compelled to do so on account of the form of the flower. The tube is large…so that most bumblebee workers could easily reach the nectar if the tube were not curved in the opposite direction from that of most flowers, and if the anthers did not obstruct the entrance." Sometimes small bees, despairing of getting into the tube through the mouth, suck at holes in the flower's sides, because legitimate feasting was made too difficult for the poor little things. The ruby-throated hummingbird, hovering a second above the tube, drains it with none of the clown-like performances exacted from the bumblebee. Pilfering ants find death as speedy on the sticky surfaces here as on any catchfly.

GREATER BLADDERWORT; HOODED WATER-MILFOIL; POP-WEED
(Utricularia vulgaris) Bladderwort family

Flowers - Yellow, about 1/2 in. across, 3 to 20 on short pedicels in a raceme at the top of a stout, naked scape 3 to 14 in. high. Calyx deeply 2-lobed; corolla 2-lipped, the upper lip erect, the lower lip larger, its palate prominent, the lip slightly 3-lobed, and spurred at the base; 2 stamens; 1 pistil; the stigma 2-lipped. Leaves: Very finely divided into threadlike segments, bearing little air bladders. Preferred Habitat - Floating free in ponds and slow streams, or rooting in mud. Flowering Season - June-August. Distribution - Throughout nearly the whole of North America, Cuba, and Mexico. Europe and Asia.

Here is an extraordinary little plant indeed, which, by its amazing cleverness, now overruns the globe - one of the higher order of intelligence so closely akin to the animals that the gulf which separates such from them seems not very wide after all. In studying the water-crowfoots (q.v.) and other aquatic plants, we learned why submerged leaves must be so finely cut; but what mean the little bladders tipped with bristles among the pop-weed's threadlike foliage? Formerly these were regarded as mere floats - a thoughtless theory, for branches without bladders might have been observed floating perfectly. It is now known they are traps for capturing tiny aquatic creatures: nearly every bladder you examine under a microscope contains either minute crustaceans or larvae, worms, or lower organisms, some perhaps still alive, but most of them more or less advanced toward putrefaction - a stage hastened, it is thought, by a secretion within the bladders; for the plant cannot digest fresh food; it can only absorb, through certain processes within the bladder's walls, the fluid products of decay. The little insectivorous sundew (q.v.), on the contrary, not only digests, but afterward absorbs, animal matter. Tiny aquatic creatures, ever seeking shelter from larger ones ready to devour them, enter the pop-weed bladders by bending inward the free edge of the valve, which, being strongly elastic, snaps shut again behind them instantly. "Abandon hope, all ye who enter here," might be written above the entrance. No victim ever escapes from that prison. Scientists are not agreed that the bristles draw creatures into the bladder. Whatever touches the sensitive valves is at once drawn in. "To show how closely the edge fits," says Charles Darwin, "I may mention that my son found a daphnia which had inserted one of its antennae into the slit, and it was thus held fast during a whole day. On three or four occasions I have seen long narrow larvae, both dead and alive, wedged between the corner of the valve and collar, with half their bodies within the bladder and half out. Professor Cohn of Germany tells of immersing a plant of this bladderwort one evening in clear water swarming with tiny crustaceans, and by the next morning most of the bladders contained them, entrapped and swimming around in their prisons.

So much for what is going on below the surface of the water: what above it? Several flowers on the showy spike attract numerous insects. One alighting on the lower lip must thrust his tongue beneath the upper one to reach the nectar in the spur, passing on its way the irritable stigma, which receives any pollen he has brought in. Instantly it is touched, the stigma folds up to be out of the way of the tongue when it is withdrawn from the spur now laden with fresh pollen. It is thus that self-fertilization is escaped. Many vigorous seeds follow in each capsule. This marvelous piece of mechanism is what Thoreau termed "a dirty-conditioned flower, like a sluttish woman with a gaudy yellow bonnet"!

Not through its seeds alone, however, has the little plant succeeded in firmly establishing itself. In early autumn the stems terminate in large buds which, falling off, lie dormant all winter at the bottom of the pond. In spring they root and put forth leaves bearing bladders, which at this stage of existence are filled with water to help anchor the plant. As flowering season approaches, the bladders undergo an internal change to fit them for a change of function; they now fill with air, when the buoyed plant rises toward the surface to send up its flowering scape, while the bladders proceed with their nefarious practices to nourish it more abundantly while its system is heavily taxed.

The HORNED BLADDERWORT (U. cornuta), found in sandy swamps, along the borders of ponds, marshy lake margins, and in bogs from Newfoundland to Florida, westward to Minnesota and Texas, bears from one to six deliciously fragrant yellow flowers on its leafless scape from June to August. It is "perhaps the most fragrant flower we have," says John Burroughs. "In a warm moist atmosphere its odor is almost too strong…. Its perfume is sweet and spicy in an eminent degree." The low scape, rooting in the mud, has some root-like stems and branches, sometimes with a few entire leaves and bladders. Its benefactors, bumblebees and butterflies, with their highly developed aesthetic taste, are attracted from afar by this pleasing flower, whose acute, curved spur filled with nectar may not be drained by small fry, to whom the hairy throat is an additional discouragement.

SWEET WILD HONEYSUCKLE, or WOODBINE; ITALIAN OR PERFOLIATE
HONEYSUCKLE
(Lonicera Caprifoliuin; L. grata of Gray) Honeysuckle family

Flowers - White within, the tube pinkish, soon fading yellow, 1 to 1 1/2 in. long, very fragrant; borne in terminal whorls seated in the united pair of upper leaves. Calyx small, 5-toothed; corolla slender, tubular, 2-lipped; upper lip 4-lobed; lower lip narrow, curved downward; 5 stamens and 1 style far protruding. Stem: Climbing high, smooth. Leaves: Upper pairs united around the stem into an oval disk or shallow cup; lower leaves opposite, but not united oval, entire. Fruit: Red berries, clustered. Preferred Habitat - Thickets, wayside hedges, rocky woodlands. Flowering Season - May-June. Distribution - New England and Michigan to the Southern States.

"Escaped from cultivation and naturalized." How does it happen that this vine, a native of Europe, is now so common in the Eastern United States as to be called the American woodbine? Had Columbus been a botanist and wandered about our continent in search of flowers, he would have found very few that were familiar to him at home, except such as were common both to Europe and Asia also. Where the Aleutian Islands jut far out into the Pacific, and the strongest of ocean currents flows our way, must once have been a substantial highroad for beasts, birds, and vegetables, if not for men as well; but in the wide, briny Atlantic no European seed could live long enough to germinate after drifting across to our shores, if, indeed, it ever reached here. Once the American colonies came to be peopled, with homesick Europeans, who sent home for everything portable they had loved there, enormous numbers of trees, shrubs, plants, and seeds were respectably carried across in ships; the seeds of others stole a passage, as they do this day, among the hay used in packing. This was the chance for expansion they had been waiting for for ages. While many cultivated species found it practically impossible to escape from the vigilance of gardeners here, others, with a better plan for disseminating seed, quickly ran wild. Now some of the commonest plants we have are of European origin. This honeysuckle, by bearing red berries to attract migrating birds in autumn, soon escaped the confines of gardens. Its undigested seeds, dropped in the woodland far from the parent vine, germinated quite as readily as in Europe, and pursued in peace their natural mode of existence, until here too we now have banks

"Quite over-canopied with luscious woodbine."

The HAIRY HONEYSUCKLE, or ROUGH WOODBINE (L. hirsuta), with a more northerly and westerly range, bears clusters of flowers that are yellow on the outside, and orange within the tube, the terminal clusters slightly elevated above a united pair of dull green leaves that are softly hairy underneath. The slender flower tube is sticky outside to protect it from pilfering ants, and the hairs at the base of the stamens serve to hide the nectar from unbidden guests. Berries, bright orange. Flowering season, June-July.

The deliciously fragrant CHINESE or JAPANESE HONEYSUCKLE (L. Japonica), as commonly grown on garden trellises and fences here as the morning-glory, has freely escaped from cultivation from New York southward to West Virginia and North Carolina. Everyone must be familiar with the pairs of slender, tubular, two-lipped, white or pinkish flowers, quickly turning yellow, which are borne in the leaf axils along the sprays. The smooth, dark green, opposite leaves, pale beneath, cling almost the entire year through. The stem, in winding, follows the course taken by the hands of a clock. Were the berries red instead of black, they would, doubtless, have attracted more birds to disperse their seeds, and the vine would have traveled as fast in its wild state as the Italian honeysuckle has done. It blooms from June to August, and sparingly again in autumn. When daylight begins to fade, these long, slender-tubed buds expand to welcome their chosen benefactors, the sphinx moths, wooing them with fragrance so especially strong and sweet at this time that, long after dark, guests may be guided from afar by it alone, and entertaining them with copious draughts of deeply hidden nectar, which their long tongues alone may drain. Poised above the blossoms, they sip without pause of their whirring wings, and it is not strange that many people mistake them in the half light for hummingbirds. Indeed, they are often called hummingbird moths. Darting away suddenly and swift as thought, they have also earned the name of hawk moths. Because the caterpillars have a curious trick of raising the fore part of their bodies and remaining motionless so long (like an Egyptian sphinx), the commoner name seems most appropriate. A sphinx moth at rest curls up its exceedingly long tongue like .a watch- spring: in action only the hummingbird can penetrate to such depths; hence that honeysuckle which prefers to woo the tiny bird, whose decided preference is for red, is the TRUMPET or CORAL HONEYSUCKLE; whereas the other twiners developed deep, tubular flowers that are white or yellow, so that the moths may see them in the dark, when red blossoms are engulfed in the prevailing blackness. Moreover, the latter bloom at a season when the crepuscular and nocturnal moths are most abundant. Rough rounded pollen grains, carried on the hairs and scales on the under side of the moth's body from his head to his abdomen, including antennae, tongue, legs, and wings, cannot but be rubbed off on the protruding sticky stigma of the next honeysuckle tube entered; hence cross-fertilization is regularly effected by moths alone. The next day such interlopers as bees, flies, butterflies, and even the outwitted hummingbird, may take whatever nectar or pollen remains. If the previous evening has been calm and fine, they will find little or none; but if the night has been wild and stormy, keeping the moths under cover, the tubes will brim with sweets. After fertilization the corolla turns yellow to let visitors know the mutual benefit association has gone out of business.

BUSH HONEYSUCKLE; GRAVEL-WEED
(Diervilla Diervilla; D. trifida of Gray) Honeysuckle family

Flowers - Yellow, small, fragrant, 1 to 5 (usually 3) together on a peduncle from upper leaf-axils. Calyx tube slender, elongated; corolla narrowly funnel-form, about 3/4 in. long, its 5 lobes spreading, 3 of them somewhat united; 5 stamens; 1 pistil projecting. Stem: A smooth, branching shrub 2 to 4 ft. high. Leaves. Opposite, oval, and taper-pointed, finely saw-edged. Fruit: Slender, beaked pods crowned with the 5 calyx lobes. Preferred Habitat - Dry or rocky soil, woodlands, hills. Flowering Season - May-August. Distribution - British Possessions southward to Michigan and North Carolina.

The coral honeysuckle determined to woo the hummingbird by wearing his favorite color; the twining white and yellow honeysuckles of our porches chose for their benefactors the sphinx moths, attracting them by delicious fragrance and deeply hidden nectar in slender tubes that are visible even in the dark; whereas the small-flowered bush honeysuckles still cater to the bees which, in all probability, once sufficed for the entire family. For them a conspicuous landing place has been provided in the more highly colored lower lobe of this flower, from which the visitor cannot fail to find the pocket full of nectar that swells the base of the tube but when he alights, pollen laden from another blossom, he must pay toll by leaving some of the vitalizing dust on the projecting stigma before he feasts and dusts himself afresh. After they have been plundered, and consequently fertilized, all the honeysuckles change color, this one taking on a deeper yellow to let the bees know the larder is empty, that they may waste no precious time, but confine their visits where they are needed. "Many flowers adapted to bees show butterflies, hawk moths and hummingbirds as intruders," says Professor Robertson; "and this is important, since it enables us to understand how bee-flowers might become modified to suit them" - just as certain of the honeysuckles have done. Once the Oriental pink weigelias, grown in nearly every American garden, were thought to belong to the Diervilla clan, from which later-day systematists have banished them.

The EARLY FLY or TWIN HONEYSUCKLE (Lonicera ciliata), found in moist, cool woods from Pennsylvania and Michigan far northward, sends forth pairs of funnel-form, honey-yellow flowers, about three-quarters of an inch long, with five, regular lobes, on a slender footstalk from the leaf axils in May. It is a straggling, shrubby bush from three to five feet tall. The opposite leaves are thin, oval, bright green on both sides, the edges hairy. Two little ovoid, light red berries follow the flowers.

Another species, a shrubby SWAMP FLY-HONEYSUCKLE (L. oblongifolia), found in wet ground and bogs throughout a similar range, blooming about two weeks later, coats the under side of its young leaves with fine hairs to prevent their pores from clogging with vapors arising from its moist retreats. The little pale yellow flowers, also growing in pairs on a footstalk from the leaf axils, have their tubular corollas strongly cleft into two lips. Reddish markings within serve as pathfinders for the bumblebee, who finds so much nectar at the base that a tiny bulging pocket had to be provided to hold it. Sometimes the two flowers join below like Siamese twins, in which case the pair of crimson berries become more or less united.

"So we grew together,
Like to a double cherry, seeming parted."

One occasionally finds the pink and white twin-flowered TARTARIAN
BUSH HONEYSUCKLE (L. Tartarica) escaped from cultivation in the
Eastern States through the agency of birds which feast upon its
little round, red, translucent berries.

COMMON DANDELION; BLOWBALL; LION'S-TOOTH; PEASANT'S CLOCK
(Taraxacum Taraxacum; T. Densleonis of Gray) Chicory family

Flower-head - Solitary, golden yellow, to 2 in. across, containing 150 to 200 perfect ray florets on a flat receptacle at the top of a hollow, milky scape 2 to 18 in. tall. Leaves: From a very deep, thick, bitter root; oblong to spatulate in outline, irregularly jagged. Preferred Habitat - Lawns, fields, grassy waste places. Flowering Season - Every month in the year. Distribution - Around the civilized world.

"Dear common flower that grow'st beside the way,
Fringing the dusty road with harmless gold.
. . . .
Gold such as thine ne'er drew the Spanish prow
Through the primeval hush of Indian seas,
Nor wrinkled the lean brow
Of age, to rob the lover's heart of ease.
'Tis the spring's largess, which she scatters now
To rich and poor alike, with lavish hand
Though most hearts never understand
To take it at God's value, but pass by
The offered wealth with unrewarded eye."

Let the triumphant Anglo-Saxon with dreams of expansion that include the round earth, the student of sociology who wishes an insight into cooperative methods as opposed to individualism, the young man anxious to learn how to get on, parents with children to be equipped for the struggle for existence, business men and employers of labor, all sit down beside the dandelion and take its lesson to heart. How has it managed without navies and armies - for it is no imperialist - to land its peaceful legions on every part of the civilized world and take possession of the soil? How can this neglected wayside composite weed triumph over the most gorgeous hothouse individual on which the horticulturist expends all the science at his command; to flourish where others give up the struggle defeated; to send its vigorous offspring abroad prepared for similar conquest of adverse conditions wherever met to attract myriads of customers to its department store, and by consummate executive ability to make every visitor unwittingly contribute to its success? Any one who doubts the dandelion's fitness to survive, should humble himself by spending days and weeks on his knees, trying to eradicate the plant from even one small lawn with a knife, only to find the turf starred with golden blossoms, or, worse still from his point of view, hoary with seed balloons, the following spring.

Deep, very deep, the stocky bitter root penetrates where heat and drought affect it not, nor nibbling rabbits, moles, grubs of insects, and other burrowers break through and steal. Cut off the upper portion only with your knife, and not one, but several, plants will likely sprout from what remains; and, however late in the season, will economize stem and leaf to produce flowers and seeds, cuddled close within the tuft, that set all your pains at naught. "Never say die" is the dandelion's motto. An exceedingly bitter medicine is extracted from the root of this dandelion, formerly known as T. officinale. Likewise are the leaves bitter. Although they appear so early in the spring, they must be especially tempting to grazing cattle and predaceous insects, the rosettes remain untouched, while other succulent, agreeable plants are devoured wholesale. Only Italians and other thrifty Old-World immigrants, who go about then with sack and knife collecting the fresh young tufts, give the plants pause but even they leave the roots intact. When boiled like spinach or eaten with French salad dressing, the bitter juices are extracted from the leaves or disguised - mean tactics by an enemy outside the dandelion's calculation. All nations know the plant by some equivalent for the name dent de lion = lion's tooth, which the jagged edges of the leaves suggest.

Presently a hollow scape arises to display the flower above the surrounding grass. Bridge builders and constructing engineers know how yielding and economical, yet how invincibly strong, is the hollow tube. March winds may buffet and bend the dandelion's stem without harm. How children delight to split this slippery tube, and run it in and out of their mouths until curls form! At the top of the scape is a double involucre of narrow, green, leaf-like scales similar to what all composites have. Half the involucre bends downward to protect the flower from crawling pilferers, half stands erect to play the role for the community of florets within that the calyx does for individual blossoms. When it is time to close the dandelion shop, business being ended for the day, this upper-half of the involucre protects it like the heavy shutters merchants put up at their windows.

Seated on a fleshy receptacle, not one flower, but often two hundred minute, perfect florets generously cooperate. "In union there is strength" is another motto adopted, not only by the chicory clan, but by the entire horde of composites. Each floret of itself could hope for no attention from busy insects; united, how gorgeously attractive these disks of overlapping rays are! Doubtless each tiny flower was once a five-petaled blossom, for in the five teeth at the top and the five lines are indications that once distinct parts have been welded together to form a more showy and suitable corolla. Each floret insures cross-pollination from insects crawling over the head, much as the minute yellow tubes in the center of a daisy do (q.v.). Quantities of small bees, wasps, flies, butterflies, and beetles - over a hundred species of insects - come seeking the nectar that wells up in each little tube, and the abundant pollen, which are greatly appreciated in early spring, when food is so scarce. In rainy weather and at night, when its benefactors are not flying, the canny dandelion closes completely to protect its precious attractions. Because the plant, which is likely to bloom every month in the year, may not always certainly reckon on being pollinated by insects, each neglected floret will curl the two spreading, sticky branches of its style so far backward that they come in contact with any pollen that has been carried out of the tube by the sweeping brushes on their tips. Occasional self-fertilization is surely better than setting no seed at all when insects fail. Not a chance does the dandelion lose to "get on."

After flowering, it again looks like a bud, lowering its head to mature seed unobserved. Presently rising on a gradually lengthened scape to elevate it where there is no interruption for the passing breeze from surrounding rivals, the transformed head, now globular, white, airy, is even more exquisite, set as it is with scores of tiny parachutes ready to sail away. A child's breath puffing out the time of day, a vireo plucking at the fluffy ball for lining to put in its nest, the summer breeze, the scythe, rake, and mowing machines, sudden gusts of winds sweeping the country before thunderstorms - these are among the agents that set the flying vagabonds free. In the hay used for packing they travel to foreign lands in ships, and, once landed, readily adapt themselves to conditions as they find them. After soaking in the briny ocean for twenty-eight days - long enough for a current to carry them a thousand miles along the coast - they are still able to germinate.

The DWARF DANDELION, CYNTHIA, or VIRGINIA GOATSBEARD (Adepogon Virginicum; formerly Krigia Virginica) - with from two to six long-peduncled, flat, deep yellow or reddish-orange flower heads, about an inch and a half across, on the summit of its stem from May to October, elects to grow in moist meadows, woodlands, and shady rocky places. How it glorifies them! From a tuffet of spatulate, wavy-toothed or entire leaves, the smooth, shining, branching stem arises bearing a single oblong, clasping leaf below the middle. Particularly beautiful is its silvery seed-ball, the pappus consisting of about a dozen hairlike bristles inside a ring of small oblong scales, on which the seed sails away. Range, from Massachusetts to Manitoba, south to Georgia and Kansas.

A charming little plant, the CAROLINA DWARF DANDELION or KRIGIA (A. Carolinianum), once confounded with the above, sends up several unbranched scapes from the same tuffet. It blooms in dry, sandy soil from April to August, from Maine and Minnesota to the Gulf States.

Like a small edition of Lowell's "dear common flower" is the TALL DANDELION, or AUTUMNAL HAWKBIT (Leontodon autumnale), its slender, wiry, branching scape six inches to two feet high, terminated by several flower-heads, each on a separate peduncle, which is usually a little thickened and scaly just below it. Only forty to seventy five-toothed ray florets spread in a flat golden disk from an oblong involucre. They close in rainy weather and at night. From June to November, in spite of its common name, it blooms in fields and along roadsides, its brownish seed-plumes rapidly following; but these are produced at the frightfully extravagant cost of over two hundred thousand grains of pollen to each head, it is estimated. The Greek generic name, meaning lion's tooth, refers to the shape of the lobes of the narrowly oblong leaves in a tuft at the base. Range, from New Jersey and Ohio far northward. Naturalized from Europe and Asia.

FIELD SOW-THISTLE; MILK THISTLE
(Sonchus arvensis) Chicory family

Flower-heads - Bright yellow, very showy, to 2 in. across, several or numerous, on rough peduncles in a spreading cluster. Involucre nearly 1 in. high; the scales narrow, rough. Stem: 2 to 4 ft. high, leafy below, naked, and paniculately branched above, from deep roots and creeping rootstocks. Leaves: Long, narrow, spiny, but not sharp-toothed; deeply cut, mostly clasping at base. Preferred Habitat - Meadows, fields, roadsides, saltwater marshes. Flowering Season - July-October. Distribution - Newfoundland to Minnesota and Utah, south to New Jersey.

It cannot be long, at their present rate of increase, before this and its sister immigrant become very common weeds throughout our entire area, as they are in Europe and Asia.

The ANNUAL SOW-THISTLE or HARE'S LETTUCE (S. oleraceus), its smaller, pale yellow flower-heads, with smooth involucres more closely grouped, now occupies our fields and waste places with the assurance of a native. Honeybees chiefly, but many other bees, wasps, brilliant little flower-flies (Syrphidae), and butterflies among other winged visitors which alight on the flowers, from May to November, are responsible for the copious, soft, fine, white-plumed seeds that the winds waft away to fresh colonizing ground. The leaves clasp the stem by deep ear-like or arrow-shaped lobes, or the large lower ones are on petioles, lyrate-pinnatifid, the terminal division commonly large and triangular; the margins all toothed. Frugal European peasants use them as a potherb or salad. One of the plant's common folk-names in the Old World is hare's palace. According to the "Grete Herbale," if "the hare come under it, he is sure no beast can touch hym!' That was the spot Brer Rabbit was looking for when Brer Fox lay low! Another early writer declares that "when hares are overcome with heat they eat of an herb called hare's-lettuce, hare's-house, hare's-palace; and there is no disease in this beast the cure whereof she does not seek for in this herb." Who has detected our cottontails nibbling the succulent leaves?

TALL or WILD LETTUCE; WILD OPIUM
(Lactuca Canadensis) Chicory family

Flower-heads - Numerous small, about 1/4 in. across, involucre cylindric, rays pale yellow; followed by abundant, soft, bright white pappus; the heads growing in loose, branching, terminal clusters. Stem: Smooth, 3 to 10 ft. high, leafy up to the flower panicle; juice milky. Leaves: Upper ones lance shaped; lower ones often 1 ft. long, wavy-lobed, often pinnatifid, taper pointed, narrowed into flat petioles. Preferred Habitat - Moist, open ground; roadsides. Flowering Season - June-November. Distribution - Georgia, westward to Arkansas, north to the British Possessions.

Few gardeners allow the table lettuce (sativa) to go to seed but as it is next of kin to this common wayside weed, it bears a strong likeness to it in the loose, narrow panicles of cream-colored flowers, followed by more charming, bright white little pompons. Where the garden varieties originated, or what they were, nobody knows. Herodotus says lettuce was eaten as a salad in 550 B.C.; in Pliny's time it was cultivated, and even blanched, so as to be had at all seasons of the year by the Romans. Among the privy-purse expenses of Henry VIII is a reward to a certain gardener for bringing "lettuze" and cherries to Hampton Court. Quaint old Parkinson, enumerating "the vertues of the lettice," says, "They all cool a hot and fainting stomache." When the milky juice has been thickened (lactucarium), it is sometimes used as a substitute for opium by regular practitioners - a fluid employed by the plants themselves, it is thought, to discourage creatures from feasting at their expense (see milkweed). Certain caterpillars, however, eat the leaves readily; but offer lettuce or poppy foliage to grazing cattle, and they will go without food rather than touch it.

"What's one man's poison, Signor,
Is another's meat or drink."

Rabbits, for example, have been fed on the deadly nightshade for a week without injury.

The HAIRY or RED WILD LETTUCE (L. hirsuta), similar to the preceding, but often with dark reddish stem, peduncles, and tiny flower-cups, the ray florets varying from yellow to pale reddish or purplish, has longer leaves, deeply cut or lobed almost to the wide midrib. After what we learned when studying the barberry and the prickly pear cactus, for example, about plants that choose to live in dry soil, it is not surprising to find that this is a lower, less leafy, and more hairy plant than the moisture-loving tall lettuce.

An European immigrant, naturalized here but recently, the PRICKLY LETTUCE (L. Scariola) has nevertheless made itself so very much at home in a short time that it has already become a troublesome weed from New England to Pennsylvania, westward to Minnesota and Missouri. But when we calculate that every plant produces over eight thousand fluffy white-winged seeds on its narrow panicle, ready to sail away on the first breeze, no wonder so well endowed and prolific an invader marches triumphantly across continents. The long, pale green, spiny-margined, milky leaves, with stiff prickles on the midrib beneath, are doubly protected against insect borers and grazing cattle.

"Look at this delicate plant that lifts its head from the
meadow;
See how its leaves all point to the North as true as the
magnet."

While Longfellow must have had the coarse-growing, yellow-flowered, daisy-like PRAIRIE ROSIN-WEED (Silphium laciniatum) in mind when he wrote this stanza of "Evangeline," his lines apply with more exactness to the delicate prickly lettuce, our eastern compass plant. Not until 1895 did Professor J. C. Arthur discover that when the garden lettuce is allowed to flower, its stem leaves also exhibit polarity. The great lower leaves of the rosin-weed, which stand nearly vertical, with their faces to the east and west, and their edges to the north and south, have directed many a traveler, not from Acadia only, across the prairie until it has earned the titles pilot-weed, compass or polar plant. Various theories have been advanced to account for the curious phenomenon, some claiming that the leaves contained sufficient iron to reader them magnetic - a theory promptly exploded by chemical analysis. Others supposed that the resinous character of the leaves made them susceptible to magnetic influence; but as rosin is a non-conductor of electricity, of course this hypothesis likewise proved untenable. At last Dr. Asa Gray brought forward the only sensible explanation: inasmuch as both surfaces of the rosin-weed leaf are essentially alike, there being very nearly as many stomata on the upper side as on the under, both surfaces are equally sensitive to sunlight; therefore the leaf twists on its petiole until both sides share it as equally as is possible. While the polarity of the prickly lettuce leaves is by no means so marked, Dr. Gray's theory about the rosin-weed may be applied to them as well.

ORANGE or TAWNY HAWKWEED; GOLDEN MOUSE-EAR HAWKWEED; DEVIL'S
PAINT-BRUSH
(Hieracium aurantiacum) Chicory family

Flower-beads - Reddish orange; 1 in. across or less, the 5-toothed rays overlapping in several series; several heads on short peduncles in a terminal cluster. Stem: Usually leafless, or with 1 to 2 small sessile leaves; 6 to 20 in. high, slender, hairy, from a tuft of hairy, spatulate, or oblong leaves at the base. Preferred Habitat - Fields, woods, roadsides, dry places. Flowering Season - June-September. Distribution - Pennsylvania and Middle States northward into British Possessions.

Peculiar reddish-orange disks, similar in shade to the butterfly weed's umbels, attract our eyes no less than those of the bees, flies, and butterflies for whom such splendor was designed. After cross-fertilization has been effected, chiefly through the agency of the smaller bees, a single row of slender, brownish, persistent bristles attached to the seeds transforms the head into the "devil's paint-brush." Another popular title in England, from whence the plant originally came, is Grimm the Collier. All the plants in this genus take their name from hierax = a hawk, because people in the old country once thought that birds of prey swooped earthward to sharpen their eyesight with leaves of the hawkweed, hawkbit, or speerhawk, as they are variously called. Transplanted into the garden, the orange hawkweed forms a spreading mass of unusual, splendid color.

The RATTLESNAKE-WEED, EARLY or VEIN-LEAF HAWKWEED, SNAKE or POOR ROBIN'S PLANTAIN (H. venosum), with flower-heads only about half an inch across, sends up a smooth, slender stem, paniculately branched above, to display the numerous dandelion-yellow disks as early as May, although October is not too late to find this generous bloomer in pine woodlands, dry thickets, and sandy soil. Purplish-veined oval leaves, more or less hairy, that spread in a tuft next the ground, are probably as efficacious in curing snakebites as those of the rattlesnake plantain (q.v.). When a credulous generation believed that the Creator had indicated with some sign on each plant the special use for which each was intended, many leaves were found to have veinings suggesting the marks on a snake's body; therefore, by simple reasoning, they must extract venom. How delightful is faith cure!

Unlike the preceding, the CANADA HAWKWEED (H. Canadense), lacks a basal tuft at flowering time, but its firm stem, that may be any height from one to five feet, is amply furnished with oblong to lance-shaped leaves seated on it, their midrib prominent, the margins sparingly but sharply toothed. In dry, open woods and thickets, and along shady roadsides, its loosely clustered heads of clear yellow, about one inch across, are displayed from July to September; and later the copious brown bristles remain for sparrows to peck at.

The ROUGH HAWKWEED (H. scabrum), with a stout, stiff stem crowned with a narrow branching cluster of small yellow flower-heads on dark bristly peduncles, also lacks a basal tuft at flowering time. Its hairy oblong leaves are seated on the rigid stem. In dry, open places, clearings, and woodlands from Nova Scotia to Georgia, and westward to Nebraska, it blooms from July to September.

More slender and sprightly is the HAIRY HAWKWEED (H. Gronovii), common in sterile soil from Massachusetts and Illinois to the Gulf States. The basal leaves and lower part of the stiff stem, especially, are hairy, not to allow too free transpiration of precious moisture.

GOLDEN ASTER
(Chrysopsis Mariana) Thistle family

Plower-heads - Composite, yellow, 1 in. wide or less, a few corymbed flowers on glandular stalks; each composed of perfect tubular disk florets surrounded by pistillate ray florets the involucre campanulate, its narrow bracts overlapping in several series. Stem: Stout, silky-hairy when young, nearly smooth later, 1 to 2 1/2 ft. tall. Leaves: Alternate, oblong to spatulate, entire. Preferred Habitat - Dry soil, or sandy, not far inland. Flowering Season - August-September. Distribution - Long Island and Pennsylvania to the Gulf States.

Whoever comes upon clumps of these handsome flowers by the dusty roadside cannot but be impressed with the appropriateness of their generic name (Chrysos = gold; opsis = aspect). Farther westward, north and south. it is the HAIRY GOLDEN ASTER (C. villosa), a pale, hoary-haired plant with similar flowers borne at midsummer, that is the common species.

GOLDENRODS
(Solidago) Thistle family

When these flowers transform whole acres into "fields of the cloth-of-gold," the slender wands swaying by every roadside, and purple asters add the final touch of imperial splendor to the autumn landscape, already glorious with gold and crimson, is any parterre of Nature's garden the world around more gorgeous than that portion of it we are pleased to call ours? Within its limits eighty-five species of goldenrod flourish, while a few have strayed into Mexico and South America, and only two or three belong to Europe, where many of ours are tenderly cultivated in gardens, as they should be here, had not Nature been so lavish. To name all these species, or the asters, the sparrows, and the warblers at sight is a feat probably no one living can perform; nevertheless, certain of the commoner goldenrods have well-defined peculiarities that a little field practice soon fixes in the novice's mind.

Along shady roadsides, and in moist woods and thickets, from August to October, the BLUE-STEMMED, WREATH or WOODLAND GOLDENROD (S. caesia) sways an unbranched stem with a bluish bloom on it. It is studded with pale golden clusters of tiny florets in the axils of lance-shaped, feather-veined leaves for nearly its entire length. Range from Maine, Ontario, and Minnesota to the Gulf States. None is prettier, more dainty, than this common species.

In rich woodlands and thicket borders we find the ZIG-ZAG or BROAD-LEAVED GOLDENROD (S. flexicaulis; S. latifolia of Gray) its prolonged, angled stem that grows as if waveringly uncertain of the proper direction to take, strung with small clusters of yellow florets, somewhat after the manner of the preceding species. But its saw-edged leaves are ovate, sharply tapering to a point, and narrowed at the base into petioles. It blooms from July to September. Range from New Brunswick to Georgia, and westward beyond the Mississippi.

During the same blooming period, and through a similar range, our only albino, with an Irish-bull name, the WHITE GOLDENROD, or more properly SILVER-ROD (S. bicolor), cannot be mistaken. Its cream-white florets also grow in little clusters from the upper axils of a usually simple and hairy gray stem six inches to four feet high. Most of the heads are crowded in a narrow, terminal pyramidal cluster. This plant approaches more nearly the idea of a rod than its relatives. The leaves; which are broadly oblong toward the base of the stem, and narrowed into long margined petioles, are frequently quite hairy, for the silver-rod elects to live in dry soil, and its juices must be protected from heat and too rapid transpiration.

In swamps and peat bogs the BOG GOLDENROD (S. uliginosa) sends up two to four feet high a densely flowered, oblong, terminal spire; its short branches so appressed that this stem also has a wand-like effect. The leaves, which are lance-shaped or oblong, gradually increase in size and length of petiole until the lowest often measure nine inches long. Season, July to September. Range, from Newfoundland to Pennsylvania and westward beyond the Mississippi.

Now we leave the narrow, unbranched, wand goldenrods strung with clusters of minute florets, which, however slender and charming, are certainly far less effective in the landscape than the following members of their clan which have their multitudes of florets arranged in large, compound, more or less widely branching, terminal, pyramidal clusters. On this latter plan the SHOWY or NOBLE GOLDENROD (S. speciosa) displays its splendid, dense, ascending branches of bloom from August to October. European gardeners object to planting goldenrods, complaining that they so quickly impoverish a rich bed that neighboring plants starve. This noble species becomes ignoble indeed, unless grown in rich soil, when it spreads in thrifty circular tufts. The stout stem, which often assumes reddish tints, rises from three to seven feet high, and the smooth, firm, broadly oval, saw-toothed lower leaves are long-petioled. Range, from Nova Scotia to the Carolinas, westward to Nebraska.

When crushed in the hand, the dotted, bright green, lance-shaped, entire leaves of the SWEET GOLDENROD or BLUE MOUNTAIN TEA (S. odora) cannot be mistaken, for they give forth a pleasant anise scent. The slender, simple, smooth stem is crowned with a graceful panicle, whose branches have the florets seated all on one side. Dry soil. New England to the Gulf States, July to September.

The WRINKLE-LEAVED or TALL, HAIRY GOLDENROD or BITTERWEED (S. rugosa), a perversely variable species, its hairy stem perhaps only a foot high, or, maybe, over seven feet, its rough leaves broadly oval to lance-shaped, sharply saw-edged, few if any furnished with footstems, lifts a large, compound, and gracefully curved panicle, whose florets are seated on one side of its spreading branches. Sometimes the stem branches at the summit. One usually finds it blooming in dry soil from July to November, throughout a range extending from Newfoundland and Ontario to the Gulf States.

Usually the ELM-LEAVED GOLDENROD (S. ulmifolia) sends up several slender, narrow spires of deep yellow bloom from about the same point at the summit of the smooth stem, like long, tapering fingers. Small, oblong, entire leaves are seated on these elongated sprays, while below the inflorescence the large leaves taper to a sharp point, and are coarsely and sharply toothed. In woods and copses from Maine and Minnesota to Georgia and Texas this common goldenrod blooms from July to September.

The unusually beautiful, spreading, recurved, branching panicle of bloom borne by the EARLY, PLUME, or SHARP-TOOTHED GOLDENROD or YELLOW-TOP (S. juncea), so often dried for winter decoration, may wave four feet high, but usually not over two, at the summit of a smooth, rigid stem. Toward the top, narrow, elliptical, uncut leaves are seated on the stalk; below, much larger leaves, their sharp teeth slanting forward, taper into a broad petiole, whose edges may be cut like fringe. In dry, rocky soil this is, perhaps, the first and last goldenrod to bloom, having been found as early as June, and sometimes lasting into November. Range, from North Carolina and Missouri very far north.

West of the Mississippi how beautiful are the dry prairies in autumn with the MISSOURI GOLDENROD (S. Missouriensis), its short, broad, spreading panicle waving at the summit of a smooth, slender stem from two to five feet tall. Its firm, rather thick leaves are lance-shaped, triple-nerved, entire, very rough-margined, or perhaps the lowest ones with a few scattered teeth.

Perhaps the commonest of all the lovely clan east of the Mississippi, or throughout a range extending from Arizona and Florida northward to British Columbia and New Brunswick, is the CANADA GOLDENROD or YELLOW-WEED (S. Canadensis). Surely everyone must be familiar with the large, spreading, dense-flowered panicle, with recurved sprays, that crowns a rough, hairy stem sometimes eight feet tall, or again only two feet. Its lance-shaped, acutely pointed, triple-nerved leaves are rough, and the lower ones saw-edged. From August to November one cannot fail to find it blooming in dry soil.

Most brilliantly colored of its tribe is the low-growing GRAY or FIELD GOLDENROD or DYER'S WEED (S. nemoralis). The rich, deep yellow of its little spreading, recurved, and usually one-sided panicles is admirably set off by the ashy gray, or often cottony, stem, and the hoary, grayish-green leaves in the open, sterile places where they arise from July to November. Quebec and the Northwest Territory to the Gulf States.

No longer classed as a true Solidago, but the type of a distinct genus, the LANCE-LEAVED, BUSHY, or FRAGRANT GOLDENROD (Euthamia graminifolia; formerly S. lanceolata) lifts its flat-topped, tansy-like, fragrant clusters of flower-heads from two to four feet above moist ground. From July to September it transforms whole riverbanks, low fields, and roadsides into a veritable El Dorado. Its numerous leaves are very narrow, lance-shaped, triple or five nerved, uncut, sometimes with a few resinous dots. Range, from New Brunswick to the Gulf, and westward to Nebraska.

"Along the roadside, like the flowers of gold
That tawny Incas for their gardens wrought,
Heavy with sunshine droops the goldenrod."

Bewildered by the multitude of species, and wondering at the enormous number of representatives of many of them, we cannot but inquire into the cause of such triumphal conquest of a continent by a single genus. Much is explained simply in the statement that goldenrods belong to the vast order of Compositae, flowers in reality made up sometimes of hundreds of minute florets united into a far-advanced socialistic community having for its motto, "In union there is strength." (See Daisy) In the first place, such an association of florets makes a far more conspicuous advertisement than a single flower, one that can be seen by insects at a great distance; for most of the composite plants live in large colonies, each plant, as well as each floret, helping the others in attracting their benefactors' attention. The facility with which insects are enabled to collect both pollen and nectar makes the goldenrods exceedingly popular restaurants. Finally, the visits of.insects are more likely to prove effectual, because any one that alights must touch several or many florets, and cross-pollinate them simply by crawling over a head. The disk florets mostly contain both stamens and pistil, while the ray florets in one series are all male. Immense numbers of wasps, hornets, bees, flies, beetles, and "bugs" feast without effort here indeed, the budding entomologist might form a large collection of Hymenoptera, Diptera, Coleoptera, and Hemiptera from among the. visitors to a single field of goldenrod alone. Usually to be discovered among the throng are the velvety black Lytta or Cantharis, that impostor wasp-beetle, the black and yellow wavy-banded, red-legged locust-tree borer, and the painted Clytus, banded with yellow and sable, squeaking contentedly as he gnaws the florets that feed him.

Where the slender, brown, plume-tipped wands etch their charming outline above the snow-covered fields, how the sparrows, finches, buntings, and juncos love to congregate, of course helping to scatter the seeds to the wind while satisfying their hunger on the swaying, down-curved stalks. Now that the leaves are gone, some of the goldenrod stems are seen to bulge as if a tiny ball were concealed under the bark. In spring a little winged tenant, a fly, will emerge from the gall that has been his cradle all winter.

ELECAMPANE; HORSEHEAL; YELLOW STARWORT
(Inula Helenium) Thistle family

Flower-heads - Large, yellow, solitary or a few, 2 to 4 in. across; on long, stout peduncles; the scaly green involucre nearly 1 in. high, holding disk florets surrounded by a fringe of long, very narrow, 3-toothed ray florets. Stem: Usually unbranched, 2 to 6 ft. high, hairy above. Leaves: Alternate, large, broadly oblong, pointed, saw-edged, rough above, woolly beneath some with heart-shaped, clasping bases. Preferred Habitat - Roadsides, fields, fence rows, damp pastures. Flowering Season - July-September. Distribution - Nova Scotia to the Carolinas, and westward to Minnesota and Missouri.

"September may be described as the month of tall weeds;" says John Burroughs. "Where they have been suffered to stand, along fences, by roadsides, and in forgotten corners,- redroot, ragweed, vervain, goldenrod, burdock, elecampane, thistles, teasels, nettles, asters, etc. - how they lift themselves up as if not afraid to be seen now! They are all outlaws; every man's hand is against them yet how surely they hold their own. They love the roadside, because here they are comparatively safe and ragged and dusty, like the common tramps that they are, they form one of the characteristic features of early fall."

Yet the elecampane has not always led a vagabond existence. Once it had its passage paid across the Atlantic, because special virtue was attributed to its thick, mucilaginous roots as a horse-medicine. For over two thousand years it has been employed by home doctors in Europe and Asia; and at first Old World immigrants thought they could not live here without the plant on their farms. Once given a chance to naturalize itself, no composite is slow in seizing it. The vigorous elecampane, rearing its fringy, yellow disks above lichen-covered stone walls in New England, the Virginia rail fence, and the rank weedy growth along barbed-wire barriers farther west, now bids fair to cross the continent.

CUP-PLANT; INDIAN-CUP; RAGGED CUP; ROSIN-PLANT
(Silphium perfoliatum) Thistle family

Plower-heads - Yellow, nearly flat; 2 to 3 in. across; 20 to 30 narrow, pistillate ray florets, about 1 in. long, overlapping in 2 or 3 series around the perfect but sterile disk florets. Stem: 4 to 8 ft. tall, square, smooth, usually branched above. Leaves: Opposite, ovate, upper ones united by their bases to form a cup; lower ones large, coarsely toothed, and narrowed into margined petioles; all filled with resinous juice. Preferred Habitat - Moist soil, low ground near streams. Flowering Season - July-September. Distribution - Ontario, New York, and Georgia, westward to Minnesota, Nebraska, and Louisiana.

It behooves a species related to the wonderful compass-plant (q.v.) to do something unusual with its leaves; hence this one makes cups to catch rain by uniting its upper pairs. Darwin's experiments with infinitesimal doses of ammonia in stimulating leaf activity may throw some light on this singular arrangement. So many plants provide traps to catch rain, although fourteen gallons of it contain only one grain of ammonia, that we must believe there is a wise physiological reason for calling upon the leaves to assist the roots in absorbing it, A native of Western prairies, the cup-plant has now become naturalized so far east as the neighborhood 6f New York City.

FALSE SUNFLOWER; OX-EYE
(Heliopsis helianthoides; H. laevis of Gray) Thistle family

Flower-heads - Entirely golden yellow, daisy-like, 1 1/2 to 2 1/2 in. across, the perfect disk florets inserted on a convex, chaffy receptacle, and surrounded by pistillate, fertile, 3-toothed ray florets; usually numerous solitary heads borne on long peduncles from axils of upper leaves. Stem: 3 to 5 ft. tall, branching above, smooth. Leaves: Opposite, ovate, and tapering to a sharp point, sharply and evenly toothed. Preferred Habitat - Open places; rich, low ground; beside streams. Flowering Season - July-September. Distribution - Southern Canada to Florida, westward to Illinois and Kentucky.

Along the streams the numerous flower-heads of this gorgeous sunbearer shine out from afar, brightening a long, meandering course across the low-lying meadows. Like heralds of good things to come, they march a little in advance of the brilliant pageant of wild flowers that sweeps across the country from midsummer till killing frost. Most people mistake them for true, yellow-disked sunflowers, whose ray florets are neutral, not fertile as these long persistent ones are, But no one should confuse them with the dark cone-centered ox-eye daisy. Small bees, wasps, hornets, flies, little butterflies, beetles, and lower insects come to feast on the nectar and pollen within the minute tubular disk florets. The bright fulvous and black pearl crescent butterfly, with a trifle over an inch wing expanse; the common hairstreak; the even commoner little white butterfly; and the tiny black sooty wing, among others, appear to find generous entertainment here. The last named little fellow, when in the caterpillar stage, formed a cradle for himself by folding together a leaf of the ubiquitous green-flowered pigweed or lamb's quarters (Cizenopodium album) and stitching the edges together with a few silken threads. Here it slept by day, emerging only at night to feed. Usually one has not long to wait before discovering the white-dotted sooty wing among the midsummer composites.

BLACK-EYED SUSAN; YELLOW or OX-EYE DAISY; NIGGER-HEAD; GOLDEN
JERUSALEM; PURPLE CONE-FLOWER
(Rudbeckia hirta) Thistle family

Flower-heads - From 10 to 20 orange-yellow neutral rays around a conical, dark purplish-brown disk of florets containing both stamens and pistil. Stem: 1 to 3 ft. tall, hairy, rough, usually unbranched, often tufted. Leaves: Oblong to lance-shaped, thick, sparingly notched, rough. Preferred Habitat - Open sunny places; dry fields. Flowering Season - May-September. Distribution - Ontario and the Northwest Territory south to Colorado and the Gulf States.

So very many weeds having come to our Eastern shores from Europe, and marched farther and farther west year by year, it is but fair that black-eyed Susan, a native of Western clover fields, should travel toward the Atlantic in bundles of hay whenever she gets the chance, to repay Eastern farmers in their own coin. Do these gorgeous heads know that all our showy rudbeckias - some with orange red at the base of their ray florets - have become prime favorites of late years in European gardens, so offering them still another chance to overrun the Old World, to which so much American hay is shipped? Thrifty farmers may decry the importation into their mowing lots, but there is a glory to the cone-flower beside which the glitter of a gold coin fades into paltry nothingness. Having been instructed in the decorative usefulness of all this genus by European landscape gardeners, we Americans now importune the Department of Agriculture for seeds through members of Congress, even Representatives of States that have passed stringent laws against the dissemination of "weeds." Inasmuch as each black-eyed Susan puts into daily operation the business methods of the white daisy (q.v.), methods which have become a sort of creed for the entire composite horde to live by, it is plain that she may defy both farmers and legislators. Bees, wasps, flies, butterflies, and beetles could not be kept away from an entertainer so generous; for while the nectar in the deep, tubular brown florets may be drained only by long, slender tongues, pollen is accessible to all. Anyone who has had a jar of these yellow daisies standing on a polished table indoors, and tried to keep its surface free from a ring of golden dust around the flowers, knows how abundant their pollen is. There are those who vainly imagine that the slaughter of dozens of English sparrows occasionally is going to save this land of liberty from being overrun with millions of the hardy little gamins that have proved themselves so fit in the struggle for survival. As vainly may farmers try to exterminate a composite that has once taken possession of their fields.

Blazing hot sunny fields, in which black-eyed Susan feels most comfortable, suit the TALL or GREEN-HEADED CONE-FLOWER OR THIMBLEWEED (R. laciniata) not at all. Its preference is for moist thickets such as border swamps and meadow runnels. Consequently it has no need of the bristly-hairy coat that screens the yellow daisy from too tierce, sunlight, and great need of more branches and leaves. (See prickly pear.) This is a smooth, much branched plant, towering sometimes twelve feet high, though commonly not even half that height; its great lower leaves, on long petioles, have from three to seven divisions variously lobed and toothed; while the stem leaves are irregularly three to five parted or divided. The numerous showy heads, which measure from two and a half to four inches across, have from six to ten bright yellow rays drooping a trifle around a dull greenish-yellow conical disk that gradually lengthens to twice its breadth, if not more, as the seeds mature. July-September, Quebec to Montana, and southward to the Gulf of Mexico.

TALL or GIANT SUNFLOWER
(Heliainthus giganteus) Thistle family

Flower-heads - Several, on long, rough-hairy peduncles; 1 1/2 to 2 1/4 in. broad; 10 to 20 pale yellow neutral rays around a yellowish disk whose florets are perfect, fertile. Stem: 3 to 12 ft. tall, bristly-hairy, usually branching above, often reddish from a perennial, fleshy root. Leaves: Rough, firm, lance-shaped, saw-toothed, sessile. Preferred Habitat - Low ground, wet meadows, swamps. Flowering Season - August-October. Distribution - Maine to Nebraska and the Northwest Territory, south to the Gulf of Mexico.

To how many sun-shaped golden disks with outflashing rays might not the generic name of this clan (helios = the sun, anthos = a flower) be as fittingly applied: from midsummer till frost the earth seems given up to floral counterparts of his worshipful majesty. If, as we are told, one-ninth of all flowering plants in the world belong to the composite order, of which over sixteen hundred species are found in North America north of Mexico, surely over half this number are made up after the daisy pattern (q.v.), the most successful arrangement known, and the majority of these are wholly or partly yellow. Most conspicuous of the horde are the sunflowers, albeit they never reach in the wild state the gigantic dimensions and weight that cultivated, dark brown centered varieties produced from the COMMON SUNFLOWER (H. annus) have attained. For many years the origin of the latter flower, which suddenly shone forth in European gardens with unwonted splendor, was in doubt. Only lately. it was learned that when Champlain and Segur visited the Indians on Lake Huron's eastern shores about three centuries ago, they saw them cultivating this plant, which must have been brought by them from its native prairies beyond the Mississippi - a plant whose stalks furnished them with a textile fiber, its leaves fodder, its flowers a yellow dye, and its seeds, most valuable of all, food and hair oil. Early settlers in Canada were not slow in sending home to Europe so decorative and useful an acquisition. Swine, poultry, and parrots were fed on its rich seeds. Its flowers, even under Indian cultivation had already reached abnormal size. Of the sixty varied and interesting species of wild sunflowers known to scientists, all are North American. Moore's pretty statement,

"As the sunflower turns on her god when he sets
The same look which she turn'd when he rose,"

lacks only truth to make it fact. The flower does not travel daily on its stalk from east to west. Often the top of the stem turns sharply toward the light to give the leaves better exposure, but the presence or absence of a terminal flower affects its action not at all.

Formerly the garden species was thought to be a native, not of our prairies, but of Mexico and Peru, because the Spanish conquerors found it employed there as a mystic and sacred symbol, much as the Egyptians employed the lotus in their sculpture. In the temples the handmaidens wore upon their breasts plates of gold beaten into the likeness of the sunflower. But none of the eighteen species of helianthus found south of our borders produces under cultivation the great plants that stand like a golden-helmeted phalanx in every old-fashioned garden at the North. Many birds, especially those of the sparrow and finch tribe, come to feast on the oily seeds; and where is there a more charming sight than when a family of goldfinches settle upon the huge, top-heavy heads, unconsciously forming a study in sepia and gold?

On prairies west of Pennsylvania to South Dakota, Missouri, and Texas, the SAW-TOOTH SUNFLOWER (H. grosse-serratus) is common. Deep yellow instead of pale rays around a yellowish disk otherwise resemble the tall sunflower's heads in appearance as in season of bloom. The smooth stalk, with a bluish-hoary bloom on its surface, may have hairs on the branches only. Long, lance-shaped, pointed leaves, the edges of lower ones especially sharply saw-toothed, their upper surface rough, and underneath soft-hairy, are on slender, short petioles, the lower ones opposite, the upper ones alternate. Honeybees find abundant refreshment in the tubular disk florets in which many of their tribe may be caught sucking; brilliant little Syrphidae, the Bombilius cheat, and other flies come after pollen; butterflies feast here on nectar, too and greedy beetles, out for pollen, often gnaw the disks with their pinchers.

Very common in dry woodlands and in roadside thickets from Ontario to Florida, and westward to Nebraska, is the ROUGH OR WOODLAND SUNFLOWER (H. divaricatus). Its stem, which is smooth nearly to the summit, does not often exceed three feet in height, though it may be less, or twice as high. Usually all its wide-spread leaves are opposite, sessile, lance-shaped to ovate, slightly toothed, and rough on their upper surface. Few or solitary flower-heads, about two inches across, have from eight to fifteen rays round a yellow disk.

The THIN-LEAVED or TEN-PETALLED SUNFLOWER (H. decapetalus), on the contrary, chooses to dwell in moist woods and thickets, beside streams, no farther west than Michigan and Kentucky. Its smooth, branching stem may be anywhere from one foot to five feet tall; its thin, membranous, sharply saw-edged leaves, from ovate to lance-shaped, with a rounded base, roughest above and soft underneath, are commonly alternate toward the summit, while the lower ones, on slender petioles, are opposite. There are by no means always ten yellow rays around the yellow disks produced in August and September; there may be any number from eight to fifteen, although this free-flowering species, like the PALE-LEAVED WOOD SUNFLOWER (H. strumosus), an earlier bloomer, often arranges its "petals" in tens.

JERUSALEM ARTICHOKE, EARTH APPLE, CANADA POTATO, GIRASOLE (H. tuberosus), often called WILD SUNFLOWER, too, has an interesting history similar to the dark-centered, common garden sunflower's. In a musty old tome printed in 1649, and entitled "A Perfect Description of Virginia," we read that the English planters had "rootes of several kindes, Potatoes, Sparagus, Carrets and Hartichokes" - not the first mention of the artichoke by Anglo-Americans. Long before their day the Indians, who taught them its uses, had cultivated it; and wherever we see the bright yellow flowers gleaming like miniature suns above roadside thickets and fence rows in the East, we may safely infer the spot was once an aboriginal or colonial farm. White men planted it extensively for its edible tubers, which taste not unlike celery root or salsify. As early as 1617 the artichoke was introduced into Europe, and only twelve years later Parkinson records that the roots had become very plentiful and cheap in London. The Italians also cultivated it under the name Girasole Articocco (sunflower artichoke), but it did not take long for the girasole to become corrupted into Jerusalem, hence the name Jerusalem Artichoke common to this day. When the greater value of the potato came to be generally recognized, the use of artichoke roots gradually diminished. Quite different from this sunflower is the true artichoke (Cynara Scolymus), a native of Southern Europe, whose large, unopened flower-heads offer a tiny edible morsel at the base of each petal-like part.

The Jerusalem artichoke sends up from its thickened, fleshy, tuber-bearing rootstock, hairy, branching stems six to twelve feet high. Especially are the flower-stalks rough, partly to discourage pilfering crawlers. The firm, oblong leaves, taper pointed at the apex and saw-edged, are rough above, the lower leaves opposite each other on petioles, the upper alternate. The brilliant flower-heads, which are produced freely in September and October, defying frost, are about two or three inches across, and consist of from twelve to twenty lively yellow rays around a dull yellow disk. The towering prolific plant prefers moist but not wet soil from Georgia and Arkansas northward to New Brunswick and the Northwest Territory. Omnivorous small boys are not always particular about boiling, not to say washing, the roots before eating them.

LANCE-LEAVED TICKSEED; GOLDEN COREOPSIS
(Coreopsis lanceolata) Thistle family

Flowers-heads - Showy, bright golden yellow, the 6 to io wedge-shaped, coarsely toothed ray florets around yellowish disk florets soon turning brown; each head on a very long, smooth, slender footstalk. Stems. 1 to 2 ft. high, tufted. Leaves: A few seated on stem, lance-shaped to narrowly oblong; or lower ones crowded, spatulate, on slender petioles. Preferred Habitat - Open, sunny places, moist or dry. Flowering Season - May-September. Distribution - Western Ontario to Missouri and the Gulf States; escaped from gardens in the East.

Glorious masses of this prolific bloomer persistently outshine all rivals in the garden beds throughout the summer. Cut as many slender-stalked flowers and buds as you will for vases indoors, cut them by armfuls, and two more soon appear for every one taken. From seeds scattered by the wind over a dry, sandy field adjoining a Long Island garden one autumn, myriads of these flowers swarmed like yellow butterflies the next season. Very slight encouragement induces this coreopsis to run wild in the East. Grandiflora, with pinnately parted narrow leaves and similar flowers, a Southwestern species, is frequently a runaway. Bees and flies, attracted by the showy neutral rays which are borne solely for advertising purposes, unwittingly cross-fertilize the heads as they crawl over the tiny, tubular, perfect florets massed together in the central disk; for some of these florets having the pollen pushed upward by hair brushes and exposed for the visitor's benefit, while others have their sticky style branches spread to receive any vitalizing dust brought to them, it follows that quantities of vigorous seed must be set.

"There is a natural rotation of crops, as yet little understood," says Miss Going. "Where a pine forest has been cleared away, oaks come up; and a botanist can tell beforehand just what flowers will appear in the clearings of pine woods. In northern Ohio, when a piece of forestland is cleared, a particular sort of grass appears. When that is ploughed under, a growth of the golden coreopsis comes up, and the pretty yellow blossoms are followed in their turn by the plebeian rag-weed which takes possession of the entire field."

The charmingly delicate, wiry GARDEN TICKSEED, known in seedsmen's catalogues as CALLIOPSIS (Coreopsis tinctoria), which has also locally escaped to roadsides and waste places eastward, is at home in moist, rich soil from Louisiana, Arizona, and Nebraska northward into Minnesota and the British Possessions. >From May to September its fine, slender, low-growing stems are crowned with small yellow composite flowers whose rays are velvety maroon or brown at the base. (Coreopsis = like a bug, from the shape of the seeds.)

LARGER or SMOOTH BUR-MARIGOLD; BROOK SUNFLOWER
(Bidens laevis; B. chrysanthemoides of Gray) Thistle family

Flower-heads - Showy golden yellow, 1 to 2 1/2 in. across, numerous, on short peduncles; 8 to 10 neutral rays around a dingy yellowish or brown disk of tubular, perfect, fertile florets. Stem: 1 to 2 ft. high. Leaves: Opposite, sessile, lance-shaped, regularly saw-toothed. Preferred Habitat - Wet ground, swamps, ditches, meadows. Flowering Season - August-November. Distribution - Quebec and Minnesota, southward to the Gulf States and Lower California.

Next of kin to the golden coreopsis, it behooves some of the bur-marigolds to redeem their clan's reputation for ugliness and certainly the brook sunflower is a not unworthy relative. How gay the ditches and low meadows are with its bright, generous bloom in late summer, and until even the goldenrod wands turn brown! Yet all this show is expended merely for advertising purposes. The golden ray florets, sacrificing their fertility to the general welfare of the cooperative community, which each flower-head is in reality, have grown conspicuous to attract bees and wasps, butterflies, flies, and some beetles to the dingy mass of tubular florets in the center, in which nectar is concealed, while pollen is exposed for the visitors to transfer as they crawl. The rays simply make a show; within the minute, insignificant looking tubes is transacted the important business of life.

Later in the season, when the bur-marigolds are transformed into armories bristling with rusty, two-pronged, and finely-barbed pitchforks (Bidens = two teeth), our real quarrel with the tribe begins. The innocent passerby - man, woman, or child, woolly sheep, cattle with switching tails, hairy dogs or foxes, indeed, any creature within reach of the vicious grappling-hooks - must transport them on his clothing; for it is thus that these tramps have planned to get away from the parent plant in the hope of being picked off, and the seeds dropped in fresh colonizing ground; travelling in the disreputable company of their kinsmen the beggar-ticks and Spanish needles, the burdock burs, cleavers, agrimony, and tick-trefoils.

BEGGAR-TICKS, STICK-TIGHT, RAYLESS MARIGOLD, BEGGAR-LICE, PITCHFORKS, or STICK-SEED (B. frondosa) sufficiently explains its justly defamed character in its popular names. Numerous dull, dark, tawny orange flower-heads without, rays, or with insignificant ones scarcely to be detected, and surrounded by taller leaf-like bracts, add little to the beauty of the moist fields and roadsides where they rear themselves on long peduncles from July to October. The smooth, erect, branched, and often reddish, stem may be anywhere from two to nine feet tall. Usually the upper leaves are not divided, but the lower ones are pinnately compounded of three to five divisions, the segments lance-shaped or broader, and sharply toothed. As in all the bur-marigolds, we find each floret's calyx converted into a barbed implement - javelin, pitchfork, or halberd - for grappling the clothing of the first innocent victim unwittingly acting as a colonizing agent.

SNEEZEWEED; SWAMP SUNFLOWER
(Helenium autumnale) Thistle family

Flower-heads - Bright yellow, to 2 in. across, numerous, borne on long peduncles in corymb-like clusters; the rays 3 to 5 cleft, and drooping around the yellow or yellowish-brown disk. Stem: 2 to 6 ft. tall, branched above. Leaves: Alternate, firm, lance-shaped to oblong, toothed, seated on stem or the bases slightly decurrent; bitter. Preferred Habitat - Swamps, wet ground, banks of streams. Flowering Season - August-October. Distribution - Quebec to the Northwest Territory; southward to Florida and Arizona.

September, which also brings out lively masses of the swamp sunflower in the low-lying meadows, was appropriately called our golden month by an English traveler who saw for the first time the wonderful yellows in our autumn foliage, the surging seas of goldenrod; the tall, showy sunflowers, ox-eyes, rudbeckias, marigolds, and all the other glorious composites in Nature's garden, as in men's, which copy the sun's resplendent disk and rays to brighten with one final dazzling outburst the somber face of the dying year.

To the swamp sunflowers honey-bees hasten for both nectar and pollen, velvety bumblebees suck the sweets, leaf-cutter and mason bees, wasps, some butterflies, flies, and beetles visit them daily, for the round disks mature their perfect fertile florets in succession. Since the drooping ray flowers, which are pistillate only, are fertile too, there is no scarcity of seed set, much to the farmer's dismay. Most cows know enough to respect the bitter leaves' desire to be let alone; but many a pail of milk has been spoiled by a mouthful of Helenium among the herbage. Whoever cares to learn from experience why this was called the sneezeweed, must take a whiff of snuff made of the dried and powdered leaves.

The PURPLE-HEAD SNEEZEWEED (H. nudiflorum), its yellow rays sometimes wanting, occurs in the South and West.

TANSY; BITTER-BUTTONS
(Tanacetum vulgare) Thistle family

Flower-heads - Small, round, of tubular florets only, packed
within a depressed involucre, and borne, in flat-topped corymbs.
Stem: 1 1/2 to 3 ft. tall, leafy. Leaves: Deeply and pinnately
cleft into narrow, toothed divisions; strong scented.
Preferred Habitat - Roadsides; commonly escaped from gardens.
Flowering Season - July-September.
Distribution - Nova Scotia, westward to Minnesota, south to
Missouri and North Carolina. Naturalized from Europe.

"In the spring time, are made with the leaves hereof newly sprung up, and with eggs, cakes or Tansies which be pleasant in taste and goode for the Stomache," wrote quaint old Gerarde. That these were popular dainties in the seventeenth century we further know through Pepys, who made a "pretty dinner" for some guests, to wit: "A brace of stewed carps, six roasted chickens, and a jowl of salmon, hot, for the first course; a tansy, and two neat's tongues, and cheese, the second." Cole's "Art of Simpling," published in 1656, assures maidens that tansy leaves laid to soak in buttermilk for nine days "maketh the complexion very fair." Tansy tea, in short, cured every ill that flesh is heir to, according to the simple faith of mediaeval herbalists - a faith surviving in some old women even to this day. The name is said to be a corruption of athanasia, derived from two Greek words meaning immortality. When some monks in reading Lucian came across the passage where Jove, speaking of Ganymede to Mercury, says, "Take him hence, and when he has tasted immortality let him return to us," their literal minds inferred that this plant must have been what Ganymede tasted, hence they named it athanasia! So great credence having been given to its medicinal powers in Europe, it is not strange the colonists felt they could not live in the New World without tansy. Strong-scented pungent tufts topped with bright yellow buttons - runaways from old gardens - are a conspicuous feature along many a roadside leading to colonial homesteads.

GOLDEN RAGWORT; GROUNDSEL; SQUAW-WEED
(Senecio aureus) Thistle family

Flower-heads - Golden yellow, about 3/4 in. across, borne on slender peduncles in a loose, leafless cluster; rays 8 to 12 around minute disk florets. Stem: Slender, 1 to 2 1/2 ft. high, solitary or tufted, from a strong-scented root. Leaves: From the root, on long petioles, rounded or heart-shaped, scalloped-edged, often purplish; stem leaves variable, lance-shaped or lyrate, deeply cut, sessile. Preferred Habitat - Swamps, wet ground, meadows. Flowering Season - May-July. Distribution - Gulf States northward to Missouri, Ontario, and Newfoundland.

While the aster clan is the largest we have in North America, this genus Senecio is really the most numerous branch of the great composite tribe, numbering as it does nearly a thousand species, represented in all quarters of the earth. It is said to take its name from senex = an old man, in reference to the white hairs on many species; or, more likely, to the silky pappus that soon makes the fertile disks hoary headed. "I see the downy heads of the senecio gone to seed, thistle like but small," wrote Thoreau in his journal under date of July 2nd, when only the pussy-toes everlasting could have plumed its seeds for flight over the dry uplands in a similar fashion. Innumerable as the yellow, daisy-like composites are, most of them appear in late summer or autumn, and so the novice should have little difficulty in naming these loosely clustered, bright, early blooming small heads.
