LILY FAMILY 301 



as low as 2300 feet (Dunsmuir, Hall # Bahcocl). Specimens from Stirling (Heller 10812) 

 and Old Cow Creek, Sha.sta Co. (M. S. Baker), have the usual curved type of gland, but in 

 coloration and size of flowers represent certain of the stages in the gradual transition to the 

 var. maweanus. This variety indeed is too close to C. tolmiei H. & A. of the Willamette 

 Valley, somewhat as the species is very closely allied to C. elegans Pursh of Idaho. The 

 fimbriae of the scale and the crest are covered with slender microscopic papillae in both the 

 species and the variety. While the variation of the gland in the species as here accepted is 

 marked, it is far less than in, for example, C. luteus. 



Var. maweanus Jepson n. comb. Pussy Eaks. Sepals commonly very blue; petals pur- 

 plish blue to wliitc, 7 to 11 lines long, the margin entire or nearly so; gland horseshoe-shaped 

 or semicircular, narrow, more or less pocketed; crest usually rather dense. — Marin Co. north 

 through the Coast Ranges to Himiboldt Co.
