B. Cucullaria Malep: Bull,, W.. Va. Agr. Exp. .Sta. ii, 327, .Leaves 
usually 2 to each stem, long petioled, triternately decompound, the prim- 
ary and eee divisions petiolate, ultimate divisions laciniately pin- 
natifid with oblong-linear mucronulate lobes: scapes 6-10 inches high, 
from a kind of scaly, fleshy bulb composed of the triangular bases of former 
leaves; several flowered; corolla white with yellowish tips, the spurs 
divergent, short and rounded, not longer than the pedicel: crest of the 
inner petals small, semi-oval, bladdery. Along the Columbia river from 
below the Cascades to Idaho, and the Eastern States. Ours differs from the 
eastern plant in having much shorter and rounded spurs. = 
B. uniflora. Dicentra uniflora, Kell. Proc. Cal. Acad, Sci. iv, 141. 
Leaves ternately or somewhat pinnately divided, the 3-7 divisions pinnati- 
fid into a few spatulate lobes: scapes 3-5 inches high, from a fascicle of 
narrow-fusiform and perpendicular fleshy tubers, 2-38 bracted, and 1--2- 
flowered: outer petals merely gibbous-saccate at base, their spatulate- 
linear recurving tips much longer than the body; inner petals with lamina 
dilated and hastate at base directly from the oblong-linear claw. On 
Mount Adams, Washington, to the Sierra Nevada in California, and 
Wyoming and Utah. 
B. pauciflora, Dicentra pauciflora Watson Bot. Cal. ti, 429. Scapes 
and leaves very slender, 4--8 inches high, from running tuberiferous root- 
stocks: leaves small, 2--3-ternate, with narrow segments: flowers 1--3, 8--12 
lines long, the short stout straight. spurs not diverging: spreading or 
reflexed tips of the outer petals 3--4 lines long; inner petals with ligulate 
claw abruptly contracted at apex into a short stalk which abruptly dilates 
into the elongate-spatulate lamina. In the Siskiyou mountains Southern 
Oregon, to Tulare County, California, near perpetual snow. 
CORYDALIS Vent. Cels. t. 19. 
Herbs with variously decompound alternate leaves and white, 
rose-colored or yellow flowers in racemes opposite the leaves or 
terminal. Corolla with only one of the petals spurred or gib- 
bous and nectariferous, by tortion becoming posterior, all erect 
and comnivent up to the short tips of the outer ones. Filaments 
with a nectariferous spur-like process at the base. Style mostly 
persistent. Capule few-many-seeded. Seeds with a concave aril- 
liform crest. I retain Corydalis because no other name has been 
settled on for this genus. 
§ 1. Perennials from thickened roots with ample leaves and 
many-flowered racemes. Stigma with 6 lobes or. processes, one 
pair terminal, one medial and one basal. Capsule oval or oblong, 
rather few-seeded. NPN | 
C. Seouleri Hook. Fl. 1, 63 t. 14. Stems simple 2--4 feet high; with 2-4 
cauline leaves from a large and thickened running scaly-jointed rootstock : 
leaves very large, pinnately decompound; ultimate leafllets, oblong to 
oblong-lanceolate, entire or the teminal one deeply 3-lobed: flowers rose- 
colored, peduncles, 1--2 inches long in a loose raceme; spurs stout, 2--3 
times as long as the balance of the flower: pedicels strongly curved down- 
wards after flowering, stigma 2-lobed at the base. > Pee RY
