Culms l)i°-t tall, tufted, erect. Sheaths over-

 the sterile shoots from one-third to one-half as long 

 as the culm, the leaves narrower; panicle compris-

 at the base, its branches rigid, at length ividcly 

 spreading; spikelets, exclusive of the awns, about 

 yi' loug,numerous; empty scales acuminate, usually 

 awn-pointcd; flowering scale commonly slightly 

 shorter than the empty ones, firm, sometimes 

 spotted with purple, hispidulous above; azcns not

 spikelets numerous, crowded, acute at both ends 

 and lanceolate when closed, i"-i]i" long, on 

 shorter hispidulous pedicels which are much 

 thickened at the apex; empty scales acute, his-
