Type locality. — Not ascertained. 



Range. — Same as the species. 



Zone. — Arctic-alpine. 



Specimens examined. — Mt. Dana, rockfield on northwest side, 

 11,500 feet, Smiley 724; side of Mt. Lyell, 13,000 feet, Lemmon, 

 August 19, 1878 ; Mt. Goddard, 11,100 feet, Hall and Chandler 679 ;

This variety is well marked in the specimens collected in the rock- 

 fields above timber line but gradually acquires the appearance of the 

 typical species lower down, i.e., it is the depauperate alpine form. 

 One of the intergrades is represented by var. niontana Jones, based 

 on a collection made near ' ' Soda Springs, ' ' Nevada County. C. nudum 

 Greene has the peduncle simple, the inflorescence being strictly capi- 

 tate at the top of the 4-5 inch stem ; no. 789 from Mt. Gibbs represents 

 this. C. monospermum Greene was based on a collection made at Big 

 Cottonwood meadows, Tulare County, 10,500 feet, by F. "W. Koch : 

 though described as having two petals and being single-seeded, in the 

 sheet of this collection now in U. C, the flowers have four petals and 

 ovaries and capsules are several seeded.
