(A) Beggar-ticks; Stick-tight (Bidens frondosa) is a plant familiar, to their sorrow, to all who roam the woods and fields during fall. Who has not had the pleasant task of sitting down and, one by one, removing the little two-hooked, black seeds that hang so closely to clothing.
Beggar-ticks, in appearance, is an uninteresting weed common everywhere in moist ground or along roadsides. The stem is very branching and is from 1 to 8 feet tall. The leaves are compounded of three to five sharply toothed, lance-shaped leaflets. The flower-heads are composed of tubular brownish-yellow florets, sometimes with no surrounding rays and again with a few tiny ones.
(B) Larger Bur-marigold; Brook Sunflower (Bidens lævis) is a very attractive species while it is in flower, but later, after the little seeds have formed, it has the same disagreeable traits common to all the members of the genus. The flowers of this species are 1 to 2 in. across, having 8 or 10 large, yellow, neutral rays surrounding the dull-colored disc florets. The stem is slender and branching, the leaves lance-shaped and toothed. Common in swamps and along brooks.
(A) Common White Daisy; Ox-eye Daisy (Chrysanthemum leucanthemum) (European) is a naturalized, floral citizen. It is so common and has become so widespread that it is even better known than most of our common native flowers.
This Daisy needs no description. We have two very similar kinds differing in the shape of the leaves, one being more pinnatifid than the other. The one shown on the opposite page is the most common, a variety of leucanthemum called pinnatifidum. The other variety has the ends of the leaves rounded and finely toothed but not cut or slashed.
(B) Feverfew (Chrysanthemum parthenium) (European) is found in some places in the East as an escape from gardens. The stem grows from 1 to 2 feet tall and is quite branching. The flowers are grouped in clusters; they are much smaller than those of the last species and have a comparatively broader disc of yellow florets. The leaves are broad, deeply pinnatifid, and each division further toothed or cut. It is locally naturalized from Mass. to N. J. and westward. It blooms from June until September, the same as does the last species.
(A) Yarrow; Milfoil (Achillea millefolium) is one of the most common of our wayside weeds.
The stem is stout, gray-green, usually simple, or forking near the top. The leaves, alternating along and clasping the stem, are soft and feathery—deeply and finely bipinnatifid.
