 when exposed to the air, white Avhen subterranean. Leaves commonly 2 to 

 each stem, on long petioles, glaucous beneath, triternately decompound ; the

 Scape 6-10 inches high. Flowers somewhat secund, nodding, white or 

 cream-color, yellow at the summit. Bracts and bracteoles minute, white. 

 Inner petals carinate ; the carina not projecting beyond the sununit. Fila- 

 ments distinct; the middle one with a subulate process projecting into the 

 cavity of the spur. Stigma compressed, reniform, obtusely 4-lobed. Cap-

Rocky woods, in rich soil, Canada ! to New- York ! and west to Kentucky !

 roundish, bright yeUow, and about as large as a grain of Indian corn ( — hence 

 the popular name. Squirrel-corn), each marked with the cicatrix of the 

 fallen petiole. Leaves resembling those of D. Cucullaria, but with narrower 

 lobes; commonly but one to each scape. Petioles terete. Scape 4-6 inches 

 high. Corolla cordate-ovate, greenish-white, tinged with purple. Spurs 

 rounded and slightly incurved. Flowers fragrant. — Pursh has confounded 

 this species with his Corydalis formosa.

 the inner petals projecting beyond the summit ; raceme compound, the 

 branches cymulose ; stigma 2-horned at the apex ; leaves numerous. — DC.
