 1895-

 one or more cauline leaves below umbel; stem 2 feet in height, one to several

 yellow 'hairs; gland small, oblong; anthers yellow, linear, exceeding fila-

Described from a large plant collected by Mr. D. Cleve- 

 land at Laguna, on the edge of the desert, San Diego 



County. 



This is one of the desert species found in rocky soil in 

 various places on the desert side of San Diego County and 

 in the Cuyumaca Mountains, also at Mill Creek, near San 

 Bernardino, and in Hermit Valley, Riverside County. The 

 writer does not agree with Mr. Baker in referring this spe- 

 cies to C. hiteiis; its affinities, if any, are with C. nuttallii 

 or C. clavatiis. Following C. clavatus it is the largest flow- 

 ered, and the showiest of the yellow Mariposa lilies. 



Group 5. 



Petals nearly naked, gland round, small, and densely hairy with matted 

 hairs; leaves ashy blue, linear, deeply channeled. Desert plants.
