 united up to above the middle. 



B. CucuUaria Millsp. Bull, W. Va. Agr. Exp. Sta. ii, 327, Leaves 

 usually 2 to each stem, long petioled, triternately decompound, the prim- 

 ary and secondary divisions petiolate, ultimate divisions laciniately pin- 

 natifld 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 ^mall, 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, 2-8 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-Unear claw. On 

 Mount Adams, "Washington, to the Sierra Nevada in California, and 

 Wyoming and Utah. 



B. panciflora, Dicentra pauciflora Watson Bot. Cal. ii, 4S9. 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; l|n the Siskiyou mountains Southern

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 connivent up to the short tips of the outer ones. Filaments 

 with a necta,riferous 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 termmal, one medial and one basah Capsule oval or oblong 

 rather few-seeded. 



; C. Scoulerl Hook. Fl. 1, 63 t. 14. Stems simple 2-4 feet high, with 2-4 

 caulme 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.

 high, from strong perennial roots, leafy; leaves bipinnately divided, the 

 oblong oval leaflets acute at each end, half to an inch long : raceme term-
