Wooded hillsides: rare in the Coast Ranges (Howell Mountain, 

 Kenwood, Mt. Diablo); common in the Sierra Foothills (where first 

 collected by Hartweg in 1840). June. Examination of fresh mate- 

 rial may show in some cases as obvious a transverse ridge at base of 

 upper lip as in next. 



3. C. bicolor Benth. Chinese Houses. Simple or branching 

 from the middle, \ to 1£ ft. high, glabrous or finely pubescent and
