[*] Raceme simple, few-flowered.
1. D. Cucullària, DC. (Dutchman's Breeches.) Scape and slender-petioled leaves from a sort of granulate bulb; lobes of leaves linear; corolla with 2 divergent spurs longer than the pedicel; crest of the inner petals minute.—Rich woods, especially westward.—A very delicate plant, sending up in early spring, from the cluster of grain-like tubers crowded together in the form of a scaly bulb, the finely cut leaves and the slender scape, bearing 4–10 pretty, but odd, white flowers tipped with cream-color.
2. D. Canadénsis, DC. (Squirrel Corn.) Subterranean shoots bearing scattered grain-like tubers (resembling peas or grains of Indian corn, yellow); leaves as in n. 1; corolla merely heart-shaped, the spurs very short and rounded; crest of the inner petals conspicuous, projecting.—Rich woods, especially northward. April, May.—Flowers greenish-white tinged with rose, with the fragrance of Hyacinths.
[*][*] Racemes compound, clustered.
3. D. exímia, DC. Subterranean shoots scaly; divisions and lobes of the leaves broadly oblong; corolla oblong, 2-saccate at the base; crest of the inner petals projecting.—Rocks, western N. Y., rare, and Alleghanies of Va. May–Aug.—Coarser-leaved than the others; scapes 6–10´ high.
Corolla 1-spurred at the base (on the upper side), deciduous. Style persistent. Pod many-seeded. Seeds crested or arilled. Flowers in racemes. Our species are biennial, leafy-stemmed, and pale or glaucous. (The ancient Greek name for the crested lark.)
[*] Stem strict; flowers purplish or rose-color with yellow tips.
1. C. glaùca, Pursh. (Pale Corydalis.) Racemes panicled; spur of the corolla very short and rounded; pods erect, slender, elongated.—Rocky places; common; 6´–2° high. May–Aug.
