Ligule 0.7-1 mm, membranous, truncate, erose or shortly ciliate, finally shredding into fine cilia. Leaf-blade 15-35 cm ×c. 2 mm, folded to flat with revolute margins, strongly keeled, of similar texture to sheath, scabrid, often a few tubercle-based hairs near margins above ligule; margins and midrib pubescent-scabrid near long, fine, acicular tip. Culm 25-90 cm, internodes glabrous. Panicle 15-35 cm, spikelets in 2-4 clusters at tips of slender branches, each cluster slightly overtopped by leaf-like spathe and consisting of 2-4 spikelet-fascicles; each fascicle subtended by a spathe-like bract > spikelets but < awns; rachis 2-3.5 mm, callus-like and covered with dense fulvous hairs; segments falling with sessile and pedicelled spikelets.
