nurow, subulate before the divergence of the barren glumes, pale 
greenish; gl. I. narrowly lanceolate-acuminate, l-nerved, keel 
hispidulous, with an awn 2 its length; gl. II. linear, 1-nerved, 
narrowing to the blunt apex, which passes abruptly into a short 
awn % the length of the glume, back not keeled, glabrous ; gl. III. 
with a short shortly hairy callus, linear-oblong, convolute, 
3-nerved, nerves scabridulous, passing above into a narrow- 
linear 3-nerved stipe to the 3-branched awn; awn-branches very 
slender, the median about 4 longer than the lateral. 
Plants 2 ft. or more in height ; roots strong, tough; culms and 
suberect branches smooth, terete, wiry, nodes glabrous; sheath 
closely surrounding the internodes, glabrous, except for a few hairs 
at the mouth, ligule very short (+ line), truncate, membranous ; 
blades convolute, very slender, long, stiff, wiry, tapering to a fine
