Stigma 2-crested. Filaments monadelphous below in a tube which is adherent 

 to the corolla, diadelphous at the summit. A climbing biennial, with thrice- 

 pinnate leaves, cut-lobed delicate leaflets, and ample panicles of drooping white 

 or purplish flowers. (Dedicated by Rafinesque to Major Adlum.) 



1. A. Cirrh6sa, Raf. Wet woods; common westward. June -Oct. 

 A handsome vine, with delicate foliage, climbing by the slender young leaf- 

 stalks over high bushes ; cultivated for festoons and bowers in shaded places. 



2. DICENTBA, Bork. DUTCHMAN'S BREECHES. 



Petals slightly cohering into a heart-shaped or 2-spurred corolla, either decidu- 

 ous or withering-persistent. Stigma 2-crested and sometimes 2-horned. Fila- 

 ments slightly united in two sets. Pod 10-20-seeded. Seeds crested. Low, 

 stemless perennials (as to our wild species) with ternately compound and dis- 

 sected leaves, and racemose nodding flowers. Pedicels 2-bracted. (Name from 

 dis, twice, and Kevrpov, a spur; accidentally printed DICLYTRA in the first 

 instance, which by an erroneous conjecture was afterwards changed into Di- 



ELYTRA.) 



1. D. Cucullaria, DC. (DUTCHMAN'S BREECHES.) Scape and slen- 

 der-petioled leaves from a sort of granulate bulb ; lobes of the leaves linear ; ra- 

 ceme simple, few-flowered ; corolla with 2 divergent spurs longer than the pedicel ; 

 crest of the inner petals .minute. Rich woods, especially westward. A very deli- 

 cate 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 slen- 

 der scape, bearing 4-10 pretty, but odd, white flowers tipped with cream-color.

 to Wisconsin and Kentucky, especially northward. April, May. Flowers 

 greenish- white tinged with rose, with the fragrance of Hyacinths. 



3. D. eximia, DC. Subterranean shoots scaly; divisions and lobes of 

 the leaves broadly oblong ; raceme compound, clustered; corolla oblong, 2-saccate at 

 the base ; crest of the inner petals projecting. Rocks, W. New York, rare 

 ( Thomas, Sartwell), and Alleghanies of Virginia. May - Aug. Coarser-leaved 

 than the others ; scapes 6' - 10' high. 



3. CORYDALIS, Vent. CORYDALIS.

1. C. glatica, Pursh. (PALE CORTDALIS.) Stem upright; racemes pan- 

 icled ; spur of the purplish and yellow-tipped corolla very short and rounded ; pods
