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

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

 curved upward, very short-pedicelled, stout, 

 somewhat 4-sided ; seeds sharp-margined,
