SOME COLORADO GRASSES. 
ELYMUS SITANION (Schult). 
Stems in tufts, very smooth, growing in moist 
meadows or in the shade of woods, where it attains a 
height of 3 feet; leaves ample, sharp pointed, glaucous or 
hairy, the upper leaf often enclosing the base of the 
panicle; spike rigid, purplish when young; glumes long 
awned, much reflexed with age. 
This grass resembles Hordeum jubatum in a general 
way, and with it is a worthless weed. It is found in all 
of the mountain meadows, but is not abundant anywhere.
