G. laxa, Scribner. 
A coarse leafy grass, 2°-4° high, with a diffuse ample panicle L'- 
and oblong, somewhat turgid spikelets. Sheaths scabrous, the 
lower exceeding the internodes. Ligule about 1" long, thin, 
lacerate. Leaves 8'-15' long, 3"-4" wide, very rough-scabrous, 
both sides tapering to a sharp point or the lower ones abruptly 
sharp-pointed. Panicle 7'-9' long, the main axis and branches 
strongly scabrous, lower branches in twos or threes, the upper 
solitary, the longer and usually widely spreading lower ones 
3-5' long. Spikelets oblong or broadly ovate, 3-5-flowered, 
about 2" long, much exceeding the pedicels, and from 1 -1^ 
wide. Empty glumes unequal, scarious-margined, the larger 
second glume about one half the length of the first floret. 
Flowering glumes rounded on the back, long, broadly 
obovate, obtuse, with a narrow scarious margin above, 7-nerved, 
nerves not prominent. Palea nearly equalling the glume, the 
keels smooth, strongly curved above. Closely allied to G. Cana¬ 
densis, but the smaller spikelets are green or purple tinged, and 
the more obtuse floral glume scarcely exceeds the narrower palea.
