5. Festuca grayi (Abrams). 



Festuca rnicrostachys ciliata Gray in Beal, Grasses N. Am. 2: 585. 1896. This is 

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

 This collection is a mixture of F. confusa and F. grayi, but Beal's 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 rnicrostachys grayi Abrams, Flora Los Angeles 52. 1904. Based on Festuca 

 rnicrostachys ciliata Gray. 



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



DESCRIPTION. 



Habit of Festuca pacijica, but somewhat stouter; sheaths and sometimes the blades 

 pubescent. Inflorescence pubescent or puberulent throughout. Spikelets 3 to 5- 

 flowered. (Plate III.)
