Culms tufted, simple, slender, erect, or ascending from strongly 
geniculate lower nodes, 15 to 30 cm tall, the sterile culms naked below, 
bearing 5 to 7 crowded leaves at the summit; blades flat, lanceolate, 
rounded at base, glabrous or sparsely hispid on upper surface, sparsely 
hispid and paler beneath, 3 to 7 cm long, 6 to 12 mm wide; staminate 
inflorescence consisting of small spikelike panicles of 2 to 5 spikelets 
borne in the upper axils and at the ends of the leafy culms the lateral 
spikelets staminate, subsessile, about 3 mm long, 0.8 mm wide, acumi- 
nate, minutely puberulent, strongly nerved, the terminal spikelets in 
appearance like the pistillate ones, 7 to 8 mm long, on short obconic 
pedicels, neutral or with a rudimentary pistil; pistillate inflorescence 
consisting of small spikelike panicles of 2 or 3 fertile spikelets on short 
thickened pedicels and a few more or less rudimentary subsessile 
staminate ones borne at the ends and in the upper slightly inflated 
sheaths of low slender naked culms arising from the base; fertile 
spikelets on short thickened pedicels, 7 to 8 mm long, 2 mm wide, 
subterete, oblong-elliptic; glume and sterile lemma subequal, puberu-
