SOME COLORADO GRASSES.

AMMOPHILA LONGIFOLIA (Vasey). 
Culm smooth, reed-like, 3 to 6 feet high, from run¬ 
ning root-stocks; leaves smooth, rigid, involute, long 
pointed; sheaths loose, longer than the nodes, hairy on 
the margins; panicle slender, whitish, 6 to 10 inches long • 
branches erect, smooth, solitary or in 2s or 3s, about 2 
inches long, flower-bearing for half their length; outer 
glumes about equal, obscurely nerved; flowering glume 
lanceolate, very acute, scabrous on the strong keel, hairs 
at the base copious, spreading; palet obtuse or acute, 
shorter than its glume. 
This species occurs in isolated specimens in moist, 
alkaline soils on the plains and in the mountains, up to 
7,000 or 8,000 feet. It is thought to be too coarse to have 
much value. 
POLYPOGON MONSPELIENSIS (Desf.). 
(Beard Grass.) 
Culms simple, decumbent at the branching base, 1 to 
2 feet high ; leaves flat, acutely pointed, downy; panicle 
spicate, densely flowered, the long awns of the flowers 
being very conspicuous; spikelets one-flowered; outer 
glumes nearly equal, pubescent, long awned ; flowering- 
glumes shorter, with a slender awn from the toothed 
apex ; palet small, not awned. 
Very common on the plains in wet soils. An orna¬ 
mental grass of but little agricultural value.
