138 University of California Publications in Botany [VOL. 9 



Specimens examined. Bear Valley, 8,000 feet, Bolander in 1873 ; 

 Sierra Valley, Lemmon in 1873 ; Soda Springs, Nevada County, close 

 to snow among rocks, Jones ; ridge east of Red Clover Valley, Heller 

 and Kennedy 723; near Squaw Peak, Placer County, C. J. Fox Jr., 

 July, 1895. 



Allium obtusum Lemmon, Pitt., vol. 2, p. 69. 1890, said to be 

 near A. nevadense Wats, and A. tribracteatum Torr. and described as 

 being "Rare in the subalpine region of Gold Lake, Plumas County," 

 where the type was collected by Lemmon, June 26, 1889, is unknown 

 to me nor have I been able to find any specimens referable to it by 

 character. 



The statement made by Professor M. E. Jones (Contr. W. Coast 

 Bot., vol. 10, p. 8. 1902) that A. haematochiton Wats, grows at Soda 

 Springs, Nevada County, a station within our region, is certainly an 

 error; this species is only known from the southern Coast Ranges 

 (Ojai Valley) and southern California.
