1921] Smiley: Flora of the Sierra Nevada of California 369 



E. memhranacetis Greene (Pitt., vol. 3, p. 294. 1898), described 

 from "Eastern Oregon, at 5,000 to 6,000 feet in the mountains," seems 

 indistinguishable from the species ; the thinness of the foliage, adduced 

 to separate, is too evidently a reaction to the habitat for acceptance 

 as a valid character.
