SOME COLORADO GRASSES. 
BECKMANNIA ERUCAEFORMIS (Kost.). 
(Water Grass.) 
Stems usually very stout, smooth, 2 to 4 feet high; 
leaves rough, flat and broad, 6 inches to 1 foot long; 
sheaths loose, inflated, the upper enclosing the base of the 
panicle; ligule long; panicle in stout specimens, 1 foot 
long, rigid, secund; branches flower-bearing to the base; 
outer glumes boat-shaped, scarious margined; apex 
mucronate; flowering glume strongly keeled, apex cuspi¬ 
date ; palet equaling its glume, acutely two-tootlied; 
sterile floret very minute, stipitate under a good lens. 
There is no grass in the Rocky Mountain region that 
stock like any better than this perennial aquatic. On the 
plains, along ditch banks, it is always present in quantity. 
It occurs, sparingly, in the mountains up to high 
elevations.
