BOUTELOUA OLIGOSTACHYA (Torr). 
(Grama Grass.) 
Stems slender, 5 to 15 inches high, smooth ; cauline 
leaves three or four; sheaths smooth, shorter than the 
internodes, very hairy at the throat below, naked above; 
blades 1 to 2J inches long, narrow, involute, edges scab¬ 
rous ; radical and sterile stem leaves 1J to 3 inches long, 
1 line wide, involute; spikes one to four, usually two; 
rhachis flat, with the spikelets sessile in two crowded rows 
on one side, hairy at base, glabrous above; spikelets with one 
perfect flower, and one pediceled, abortive flower, consist¬ 
ing of two small, hyaline, empty glumes and three stiff 
awns, which nearly equal the glume of the perfect flower 
in length; the pedicel villous, tufted at the summit; 
empty glumes very unequal, both sparingly hairy on the 
back, one-nerved, the lower hyaline, the upper purple, 
awn-pointed; flowering glume lanceolate, trifid, the divi¬ 
sions subulate, copiously hairy on the back; palet two- 
nerved and two-pointed, hyaline, enclosed by the glume. 
This grass is quite abundant in this locality, both on 
the plains and in the mountains. On the mountain 
ranges visited, it is so closely fed that I failed to find 
plants in bloom, but, in places on the plains, the bloom 
is abundant.
