SOME COLORADO GRASSES. 
PHRAGMITES COMMUNIS (Trin.). 
(Reed Grass.) 
Resembles broom corn at a distance. Stems reed¬ 
like, very leafy, 5 to 12 feet high; leaves ample, smooth, 
1 or 2 inches wide; panicle loose, nodding, 1 foot or more 
long; spikelets three to five-flowered; outer glumes 
unequal, strongly keeled, acute ; flowering glumes narrow, 
membranaceous. 
This very coarse grass is comparatively rare in 
Northern Colorado and Central Wyoming, but is very 
common along the banks of the Arkansas, between 
Pueblo and Canon City. It has no value for agricultural 
purposes. 
HORDEUM JUBATUM (L.). 
(Squirrel Tail Grass.) 
Stems 6 inches to 2 feet high ; leaves flat, 2 to 4 
inches long, margins often scabrous; flowers in a dense 
spike, pale green at 5,000 feet, purplish at higher alti¬ 
tudes ; lateral flowers abortive, short awned; perfect 
floret, bearing a spreading, capillary awn, 2 inches long; 
awns very bad for stock, in feeding, causing throat diffi¬ 
culties. 
This grass has become a serious pest in wet, alkaline 
meadows in the Rocky Mountain country. Its spread is 
entirely the result of over irrigation.
