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



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

 County, 95 but is not otherwise known south, of "Washington. 



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

 Washington is said by Scribner 96 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. Leibergii 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.

Glyceria elata Hitchc. (in Jepson, Fl. Calif., vol. 1, p. 162 ; Panicu- 

 laria elata Nash, in Rydb., Mem. N. Y. Bot. Gard., vol. 1, p. 54. 1900, 

 described from "Sweet Grass Canyon, Crazy Mountains, Montana), 

 a variant of G. nervata Trin., from which it is distinguished by 

 broader leaves and a more vigorous habit of growth, but connected in 

 the Northwest with typical G. nervata by numerous intermediate 

 forms (cf. Piper, Fl. Wash. Contr. Nat. Herb., vol. 11, p. 140), 

 occurs in both the Coast Ranges and Sierra Nevada in the Transition, 

 and not infrequently rises into the boreal region along streams or in 

 rich meadows (Angora Peak, 7,500 feet, Smiley 309 ; Suzy Lake trail, 

 Tahoe, 7,100 feet, Smiley 199 ; Scandinavian Caiion, 7,000 feet, Brewer 

 2061).
