SOME COLORADO GRASSES. 
KCELERIA CRISTATA (Pers.). 
Culms erect, from a somewhat geniculate base, about 
three-leaved; leaves flat, 2 to 4 inches long, scabrous 
above; ligule lacerate, obtuse; sheaths loose, striate, 
exceeding the nodes, glabrous or downy; panicle narrow, 
spicate, interrupted below, downy at the joints of the 
rhachis; outer glumes unequal, scabrous on the keel, 
acute ; flowering glume similar, apex usually mucronate ; 
palet equaling the glume, hyaline, acutely two-toothed. 
This grass is abundantly distributed in the mountains 
on dry hillsides; also, in the partial shade of timber and 
in the native meadows, when not wet. The more robust 
forms attain a height of 2J feet. It is a promising species.

SPARTINA CYNOSUROIDES (Willd.). 
(Cord Grass.) 
Culms 3 to 6 feet high; leaves 2 to 3 feet long, 
pointed ; panicle 1 foot or more long, occupied by from five 
to twenty spreading flower-spikes, hispid on the angles ; 
outer glumes unequal, the lower linear, the upper broader, 
rough on the keel and tapering to a stout point; flower¬ 
ing glume rough on the keel above; palet thin, two- 
nerved, longer than its glume. 
Abundant in wet soils or on the banks of irrigating 
ditches. It is rejected by stock, unless cut when young. 
It has, probably, but little value.
