SOME COLORADO GRASSES. 
G6 
STIPA VIRIDULA (Trin). 
Culms 2 to 4 feet high, leafy, clothed at base with 
the sheaths of dead leaves; sheaths loose, hairy on the 
margins, striate, the uppermost enclosing the base of the 
panicle; leaves linear, soon involute, glabrous, except on 
the margins; ligule small, truncate; panicle 4 to 12 
inches long, loose and very narrow; branches usually in 
pairs, hairy at base, erect, appressed; spikelets one- 
flowered, short pediceled; outer glumes about equal, 
bristle pointed, membranous, three-nerved; flowering 
glume clothed with short hairs, which are somewhat 
longer at the toothed apex, terminating in a slender, twice 
bent, pubescent awn, which is also twisted below the 
middle; palet shorter than its glume, by which it is 
involved. 
This grass grows in tufts, in dry soils, with Festuca 
scabrellct and Festuca ovina, or, it may occupy large areas 
almost alone. It is eagerly sought for by stock.
