 A. Fendleri var. subcongesta Wats., Bot. King's Exped., p. 40. 1871. 



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

 altitude. ' ' 



Range. Same as the species. 



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

 10,600 feet, R. A. Ware 2627c; Castle Peak, in rock crevices, 8,600 

 feet, Smiley 486 ; Crescent Lake, Mariposa County, Congdon, August 

 11, 1890; Lake Tenaya, Congdon, August 14, 1894; Shuteye Mountain,

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. ca>pillaris.
