The plant, determined by Greene as C. Bloomeri, and reported by 

 Merriam {I.e.) as growing in the Hudsonian and even above timber 

 line on Mt. Shasta, has not been seen, but it is probably of this variety, 

 since W. 31. Canhy 113, collected on the same mountain at timber line, 

 is of this variety. In the Sierra, the species scarcely enters the boreal 

 region and Piper'^ assigns it to the Arid Transition exclusively in 

 Washington.

Type locality. — ''Mono Pass, at 9-10,000 feet of elevation." 

 Bolander. 



Range. — Central Sierra Nevada. 



Zone. — Canadian, rising into the Hudsonian. 



Specimens eocamined. — Mono Pass, Bolander 6135 ; Soda Springs, 

 Upper San Joaquin, Congdon, August 19, 1895; Mt. Warren, Tuol-

 County, 8-8,700 feet, H. M. and G. R. Hall 8413; Bloody Caiion, 

 Mono County, Congdon C 125. 



Coville^° refers his No. 1690 to this species but notes its disagree- 

 ment with the type of C. Bolanderi and suggests that it may belong 

 to C. Parryi (Gray) Greene of the Rocky Mountains, a species not 

 otherwise kno\^^l west of Colorado and Wj^oming. This number has 

 been made the type of C. asper Greene (Leaflets, vol. 1, p. 81. 1904). 

 I have had no opportunity to examine the specimen.
