1921] Smiley: Flora of the Sierra Nevada of California 105 



Poa arctiea R. Br. was once reported from Soda Springs, Nevada 

 County,^° but is not otherwise known south, of Washington. 



Poa saxatilis Scribn. and "Williams, an arctic-alpine species of 

 "Washington is said by Scribner^^ to be represented in typical form by 

 Hansen 1963; I do not know whether or not this is the G. E. Hansen 

 who collected and distributed so many numbers from the central 

 Sierra Nevada. 



Other Poas from the alpine districts of the Sierra have been re- 

 ferred to P. Leihergii Scribn. and P. Cottoni Piper (Jepson, I.e., p. 

 160), both described from the Arid Transition of eastern Oregon and 

 "Washington. I have not seen the specimens.
