5. Festuca grayi (Ahrama). 



Feduca rnicrostachys eiliataGrsiy in Beal, Grasses N. Am, 2: 585. 1896. This is 

 based on specimens collected by Howell at Grantis Pass, Oregon, May 24, 1884. 

 This collection is a mixture of R confusa and K grayi, but BeaPs description refers 

 clearly to the plant with pubescent lemmas. The type is in the herbarium of the 

 Michigan Agricultural College; a duplicate in the National Herbarium. 



Festuca microstacJtys grayi Abrams, Flora Los Angeles 52. 1904,' Based on Festuca 



mierostachys cdiata Gray. 



The name ciliata is preoccupied in Feduca ciliata Danth., 1805.
