Glabrous, 6'-i4' high, diffuse, branching. 

 Leaves all but the uppermost petioled, finely 

 dissected into oblong obovate or cuneate seg- 

 ments, mainly broader than those of related 

 species ; flowers 6" long, bright yellow ; spur 

 one-half the length of the body of the corolla, 

 or more, rounded ; outer petals keeled, not 

 crested; pedicels short, slender; pods spreading 

 or pendulous, torulose, especially when dry; seeds 

 obtuse-margined, shining, obscurely reticulated. 



In woods, Nova Scotia to Minnesota, Alaska, Penn- 

 sylvania and Missouri, south in the Rocky Mountains 

 to Arizona and California. March-May. 



5. Capnoides montanum (Engelm.) Brit- 

 ton. Mountain Corydalis. Fig. 1993. 



Corydalis montana Engelm. ; A. Gray, Mem. Am. 



Acad. 4 : 6. 1849. 

 Corydalis aurea var. occidentalis Engelm. ; A. Gray, 



Man. Ed. 5, 62. 1867.

Spring Fl. Manhattan, 17. 1894. 

 Capnoides montanum Britton, Mem. Torn Club 5 : 



1 66. 1894. 



Closely resembles C. aureum, but is lighter 

 green and the leaves are rather more finely 

 divided. Flower-clusters spicate-racemose, the 

 pedicels usually very short; flowers bright yel- 

 low, 6"-8" long; spur of the corolla as long as 

 its body, or less; capsules spreading or some- 

 what ascending; seeds sharp-margined, shining 

 or obscurely reticulated. 



In dry soil, South Dakota to Kansas, Texas, Utah 

 and Mexico. Perhaps a race of the preceding species. 

 April-Aug. 



6. Capnoides campestre Britton. Plains 

 Corydalis. Fig. 1994. 



Capnoides campestre Britton, Man. Ed. 2, 1065. 

 1905. 



Similar to the two preceding species. Flow- 

 ers spicate-racemose, about 8" long, conspicu- 

 ous, bright yellow; spur of the corolla 

 blunt, nearly straight, 2"-2j" long; pods 

 curved upward, very short-pedicelled, stout, 

 somewhat 4-sided ; seeds sharp-margined, 

 finely and distinctly reticulated. 



In fields and woods, Illinois to Nebraska, 

 Arkansas and Texas. April-June. Mistaken in 

 our first edition for the Texan Capnoides curvi- 

 siliquum. Golden corydalis.
