COJRYDALIS. 



petals : crests of the inner petals little surpassing their tips : all the' petals 

 united up to above the middle. 



B. Cucullaria Millsp. Bull, W. Ya. Agr. Exp. Sta. ii, S27, Leaves 

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

 ary and secondary 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, a*nd the Eastern States. Ours differs from the 

 eastern plant in having much shorter and rounded spurs. 



B. uniflora. Dicentra uniflora, Rett. Proc. Cal. Acad, Sci. iv, 1J/1. 

 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, 2-3 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. ii, 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 connivent 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 genu's. 



§ 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. 



C. Sconleri 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 learllets, 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. 



C. Cusickii Watson in Coult. Man. Rocky Mt. Reg. 14. Stems 2-3 feet 

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

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

 inal, dense ; flowers white or purplish with tips of inner petals violet, an
