 Which are connected by a transverse ridge; lateral lobes of the lower lip

 lanceolate to linear, sessile, revolute: fl. loosely racemose (1, 2 or rarely 3

 valleys of the Coast Range; plentiful in grain fields. April, May. 



7. C. sparsiflora, Fisch. & Mey. Puberulent throughout, and the 

 herbage reddish, 4—8 in. high, with few ascending branches: leaves 

 mostly lanceolate, entire, the very lowest small, rounded, toothed and
