Corydalis. PUMARIACEyE. 97 



Coulter, Mau. Rocky Mt. Reg. 14. — Blue Mountains and Eagle Creek Range, along alpine 

 watercourses, Ciiskk, 1877; W. Idaho, on the ridge above Clearwater, Watson, 1880. 

 Largest leaves 3 feet long. 

 C. Brandegei, Watson, 1. c. Stems 2 to 5 feet high : dorsal crest of the hoods obsolete 

 and rounded summit not emarginate, but margins recurved : capsules siiort-oval to oblong, 

 obtuse, reflexed on the ascending pedicels : seeds with a small arilliform crest. — Coulter, 

 1. c. — Mountains of S. W. Colorado, Brandegee, 1874, Lieut. McCauley, 1877; Utah, in the 

 Wasatch Mountains, at about 10,000 feet, on rather dry banks, M. E. Jones, 1879, Hooker & 

 Gray, 1887. 



§ 3. Annuals or (chiefly) biennials, mostly branched from the base, with finely 



dissected leaves and siliquiform capsule. 



* Stem strict : flowers purple or rose-colored with yellow tips. 



C. glauca, PuRSH. A foot or two high, except in depauperate specimens, very glaucous : 

 lobes of the leaves mostly spatulate : racemes short, panicled at the naked summit of the 

 branches : flowers barely half inch long : spur short and rounded : capsule slender and 

 linear ; seeds minutely rugulose transversely. — Fl. ii. 463 ; Hook. Fl. Bor.-Am. i. 37 ; Torr. 

 & Gray, Fl. i. 69. Fumaria sempervirens, L. Spec. ii. 700, but in no way evergreen. F. glauca, 

 Curtis, Bot. Mag. t. 179. Capnoides sempercirens, Borkh. in Ra?m. 1. c. 44. Corydalis sem- 

 pervirens, Pers. Sjai. ii. 269. — Rocky or sterile ground, Nova Scotia to the northern Rocky 

 Mountains (and even to Brit. Columbia and Arctic Coast), south to Texas; fl. summer. 

 * * Low, ascending or diffuse : flowers yellow : apparently all biennials or winter-annuals ; 

 but a common western one seemingly more enduring.^ 

 -H- Hood or sac of the outer petals at most carinate but not wing-crested upon the back. 



C. aurea, Willd. (/ommonly low and spreading : flowers golden yellow, about half inch 

 long, on rather slender pedicels in a short raceme ; spur barely half the length of the body, 

 somewliat decurved : capsules spreading or pendulous, about inch long, terete, torulose 

 when dry, 10-12-seeded : seeds turgid, obtuse at margin, the shining surface obscurely re- 

 ticulated. — Enum. 740; DC. Syst. ii. 125, partly; Hook. Fl. Bor.-Am. i. 37; Torr. & Gray, 

 Fl. i. 68, mainly; Gray, Gen. HI. i. 124, t. 52, & Mau. 29. C aurea, var. micrantha, Wats. 

 Bot. King Exp. 14. C. aurea, var. mncrantha, Wood, Bot. & Fl. 34. Fumaria aurea, Ker, 

 Bot. Reg. t. 66.- — Rocky banks. Lower Canada and N. New England, northwestward to lat. 

 64°, west to Brit. Columbia and Oregon, south to Texas, Arizona. (Adj. Mex., but nut 

 Japan.) Western forms with spur almost as long as the body of the corolla aiul passing 

 into 



Var. OCcidentalis, Engelm. More erect and cespitose, from a stouter and some- 

 times more enduring root: flowers rather larger and spur (almost as long as the body) 

 commonly ascending: capsules thicker, less torulose, sometimes minutely pruinose, mostly 

 incurved-ascending on short spreading pedicels : seeds less turgid and acutish at the margins. 

 — Engelm. in Gray (Fl. Fendl. 6), Man. ed. 5, 62. C. montana, Engelm. 1. c; Wood, Bot. 

 & Fl. 34.3 — Colorado, New Mexico, W. Texas, Arizona. (Adj. Mex.) The typical form 

 of this (well represented by Pringle's 198 from Chihuahua, and the plant about El Paso) by 

 itself seems ([uite specifically distinct, and nearly approaches the next species. 



C. eurvisiliqua, Engelm. Commonly robust, ascending or erect, a foot or less high : 

 flowers golden yellow, over half inch long, in a spiciform raceme ; spur equalling the body 

 in length, t'ommonly ascending : capsules rather stout, quadrangular, inch and a half long, 

 2 lines thick, incurved-ascending or straightish on very short and thicki.sh diverging pedicels : 

 seeds turgid-lenticular with acute margins, the surface thickly and minutely muriculate. — 

 Engelm. in Gray, Man.- ed. 5, 62. C. aurea, var. eurvisiliqua, Gray, Proc. Acad. Philad. 

 1863, 57 (but the plant of Hall & Harbour is rather C. aurea, var. occidentalis). C. aurea, 

 var.. Gray, PI. Wright, ii. 10.* — Woods and thickets. New Braunfels, &c., Texas, Lindheimer. 

 -1— -)— A conspicuous wing-like crest on the back of the hood or sac of the outer petals (not 

 developed in cleistogamous flowers).
