SOME COLORADO GRASSES. 
PANICUM GLABRUM (Gaudin). 
Stems prostrate, ascending, branching from the base; 
leaves glabrous, very short, fiat; sheaths—the lower hairy 
at the throat; spikes 2 to 4 in pairs, slender; spikelets in 
2 rows, ovate; glume and palet pubescent, becoming 
purplish with age; ligule purplish. 
This species flowers in the latter part of August and 
through September, and occurs chiefly in lawns, where it 
quickly affects the stand of blue grass, with its spreading, 
dense stems and leaves. This grass is persistent and 
widely distributed in lawns in Northern and Southern 
Colorado.

PANICUM CRUS-GALLI (L.), var. ECHINATUM (Torr). 
(Barn-Yard Grass.) 
This form has the glumes blackish, and beset, 
especially on the margins, with stiff hairs; glumes black¬ 
ish, the margins clothed with stiff hairs; one of the 
outer glumes awned. 
It is considered to be of value. There are two forms 
here, those with green glumes and those with black. In 
wet places it attains a height, late in summer, of 6°. It 
is readily eaten by horses. In gardens, it proves a form¬ 
idable weed among slender rooted plants.
