Densely tufted; culms erect, 3-jointed, mostly 15 to 60 cm. high, smooth or some- 

 what scabrous near the panicle; sheaths smooth, shorter than the internodes; ligule 

 very short, 1 mm. or less; blades pale green, strongly involute, firm, narrow, cylin- 

 dric, scabrous on the margins, the basal ones 5 to 12 cm. long, those of the culm 

 often very short; panicle contracted after blooming, commonly 5 to 10 cm. long; 

 rays ascending, scabrous on the angles; spikelets ovate or oblong, usually 5 to 7.5 mm. 

 long, 3 to 6 or rarely 9-flowered, pale green, or sometimes purplish tinged; florets 

 rather close; joints of the rachilla smooth; glumes unequal, linear-lanceolate, acute, 

 the lower 1-nerved, about 2 mm. long, the upper 3-nerved, about 2.5 mm. long; 

 lemma lanceolate, thick and firm, convex, obscurely 5-nerved, smooth or more or

This species in its typical form occurs native in North America in the Rocky 

 Mountains from Alberta to New Mexico, in the Black Hills, and about the Great 

 Lakes. Through cultivation it is more or less commonly introduced in many locali- 

 ties. The specimen referred by Beal, Grasses N. Am. 2: 600, to F. hystrix Boiss. is 

 true F. ovina.
