This species in several preceding collections from the Rocky Mount- 

 ains has been called Festuca scabrella, Torr., but upon careful comparison 

 of the figure and description of that species in Hooker's Fl. Bor. Am., I am 

 satisfied that this is a different species. — Twin Lakes, Colorado, 1873
