BLUE-EYED MARY; INNOCENCE; BROAD-LEAVED COLLINSIA
(Collinsia verna) Figwort family
Flowers - On slender, weak stalks; whorled in axils of upper leaves. Blue on lower lip of corolla, its middle lobe folded lengthwise to enclose 4 adhering stamens and pistil; upper lip white, with scalloped margins; corolla from 1/2 to 3/4 in. long, its throat about equaling the deeply 5-cleft calyx. Stem: Hoary, slender, simple or branched, from 6 in. to 2 ft. high. Leaves: Thin, opposite; upper and more acute ones clasping the stem; lower, ovate ones on short petioles. Fruit: A round capsule to which the enlarged calyx adheres. Preferred Habitat - Moist meadows, woods, and thickets. Flowering Season - April-June. Distribution - Western New York and Pennsylvania to Wisconsin, Kentucky, and Indian Territory.
Next of kin to the great Paulonia tree, whose deliciously sweet, vanilla-scented, trumpet-shaped violet flowers are happily fast becoming as common here as in their native Japan, what has this fragile, odorless blossom of the meadows in common with it? Apparently nothing; but superficial appearances count for little or nothing among scientists, to whom the structure of floral organs is of prime importance; and analysis instantly shows the close relationship between these dissimilar-looking cousins. Even without analysis one can readily see that the monkey flower is not far removed.
Because few writers have arisen as yet in the newly settled regions of the middle West and Southwest, where blue-eyed Mary dyes acres of meadow land with her heavenly color, her praises are little sung in the books, but are loudly buzzed by myriads of bees that are her most devoted lovers. "I regard the flower as especially adapted to the early flying bees with abdominal collecting brushes for pollen - i.e., species of Osmia - and these bees," says Professor Robertson of Illinois, "although not the exclusive visitors, are far more abundant and important than all the other visitors together." For them are the brownish marks on the palate provided as pathfinders. At the pressure of their strong heads the palate yields to give them entrance, and at their removal it springs back to protect the pollen against the inroads of flies, mining bees, and beetles. As the longer stamens shed their pollen before the shorter ones mature theirs, bees must visit the flower several times to collect it all.
MONKEY-FLOWER
(Minulus ringens) Figwort family
Flowers - Purple, violet, or lilac, rarely whitish; about 1 in. long, solitary, borne on slender footstems from axils of upper leaves. Calyx prismatic, 5-angled, 5-toothed; corolla irregular, tubular, narrow in throat, 2-lipped; upper lip 2-lobed, erect; under lip 3-lobed, spreading; 4 stamens, a long and a short pair, inserted on corolla tube; pistil with 2-lobed, plate-like stigma. Stem: Square, erect, usually branched, 1 to 3 ft. high. Leaves: Opposite, oblong to lance-shaped, saw-edged, mostly seated on stem. Preferred Habitat - Swamps, beside streams and ponds. Flowering Season - June-September. Distribution - Manitoba, Nebraska, and Texas, eastward to Atlantic Ocean.
No wader is the square-stemmed Monkey-flower whose grinning corolla peers at one from grassy tuffets in swamps, from the brookside, the springy soil of low meadows, and damp hollows beside the road; but moisture it must have to fill its nectary and to soften the ground for the easier transit of its creeping rootstock. Imaginative eyes see what appears to them the gaping (ringens) face of a little ape or buffoon (mimulus) in this common flower whose drolleries, such as they are, call forth the only applause desired - the buzz of insects that become pollen-laden during the entertainment.
Now the advanced stigma of this flower is peculiarly irritable, and closes up on contact with an incoming visitor's body, thus exposing the pollen-laden anthers behind it, and, except in rare cases, preventing self-fertilization. Delpino was the first to guess what advantage so sensitive a stigma might mean. Probably the smaller bees find the tube too long for their short tongues. The yellow palate, which partially guards the entrance to the nectary from pilferers, of course serves also as a pathfinder to the long-tongued bees.
AMERICAN BROOKLIME
(Veronica Americana) Figwort family
Flowers - Light blue to white, usually striped with deep blue or purple structure of flower similar to that of V. officinalis, but borne in long, loose racemes branching outward on stems that spring from axils of most of the leaves. Stem: Without hairs, usually branched, 6 in. to 3 ft. long, lying partly on ground and rooting from lower joints. Leaves: Oblong, lance-shaped, saw-edged, opposite, petioled, and lacking hairs; 1 to 3 in. long, 1/4 to 1 in. wide. Fruit: A nearly round, compressed, but not flat, capsule with flat seeds in 2 cells. Preferred Habitat - In brooks, ponds, ditches, swamps. Flowering Season - April-September. Distribution - From Atlantic to Pacific, Alaska to California and New Mexico, Quebec to Pennsylvania.
