Type locality. — "East Humboldt Mountains, Nevada, 7-9,000 feet 

 altitude. ' ' 



Range. — Same as the species. 



Specimens examined. — Castle Peak, Heller 7063 ; Mono Pass,

This variety lacks the characteristic densely clustered head of 

 flowers found in the type form, the flowers being on more or less long 

 pedicels ; in this it approaches A. capillaris, but may be distinguished 

 from that species by the thicker, shorter leaves, which are straight, 

 not curving as in A. capillaris.
