SOME COLORADO GRASSES. 
HILARIA JAMESII (Benth.). 
Stems branching from the ground; nodes hairy; 
ligule [short, laciniate; leaves glaucescent, scabrous, 
striate, hairv above; flowers in a strict spike ; the spike- 
lets in 3s, sessile, from a tuft of silky, spreading hairs, 
the lateral ones staminatc, the central one perfect; outer 
glumes of the sterile flowers scabrous, especially on the 
keel, the outer half of each glume prominently three to 
four-nerved,, sometimes with a divergent awn from near 
the middle; outer glume of the perfect flower narrow, 
cuneate, ciliate on the margins, deeply two-cleft, lobes 
about six-bristled, the one below the cleft the longest; 
flowering glume three-nerved, membranous, cuspidate 
from near the apex ; palet nearly equaling the glume? 
two-toothed. 
This grass grows in stout clumps from underground 
stems, attaining a height of from 2 to 3 feet. It occurs 
near Pueblo, on adobe soils, flowering as late as the first 
week in October. Nothing is known of its economic value. 
CINNA ARUNDINACEA (L.), var. PENDULA (Gray). 
Stems reed-like, 3 to 7 feet high, with prominent, 
brownish nodes; leaves broad and very rough; sheaths 
finely scabrous; ligule very prominent; panicle 1 foot 
long, slender, drooping at apex ; rays distant, capillary, 
unequal, in 4s or 5s, the longest flower-bearing above the 
middle; spikelets one-flowered, much flattened; outer 
glumes narrow, rough, especially on the keel, scarious 
margined, acute, the upper glume longer than the floret; 
flowering glume usually two-toothed, terminating in a 
short, straight awn, from near the apex ; palet one-nerved, 
much shorter than the glume. 
This robust species was seen near Pock Creek, Wyo., 
at an elevation of 9,000 feet, growing in deep shade in 
moist ground. Its agricultural value is unknown.
