FUMARIACE^E. (FUMITORY FAMILY.) 61 



Stigma 2-crestetl. 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. cirrildsa, Rat". — 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. DICENTEA, 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 

 bis, twice, and Kevrpov, a spur; — accidentally printed Dicly'tra in the first 

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

 e'lytra.)

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

 ceme simple, few-flowered ; corolla with 2 divergent spins 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.

 and rounded ; crest of the inner petals conspicuous, projecting. — Rich woods, Maine 

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

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

 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. 



Corolla 1 -spurred at the base (on the upper side), deciduous. Style persist- 

 ent. 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 Fumitory.) 



1. C. glauca, Pursh. (Pale Corydalis.) Stem upright ; racemes pan- 

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