Tufted perennial, 300-1200 mm high; rhizomatous; culm nodes adpressed white hairy. Leaf blade 50-200 x 5 mm, becomes hard as it ages; ligule membranous, splitting into three lobes. Inflorescence a single raceme, rarely with up to 5 racemes, 40-170 mm long, with velvety awns throughout its length. Subsessile spikelet 6-8 mm long; awnless. Long-pedicellate spikelet 8-13 mm long; upper lemma awn hairy, twisted, hygroscopic; callus white hairy; anther 5.0-5.5 mm long.

Sessile spikelet similar to the pedicelled but awnless, narrowly and usually inconspicuously winged on the margins above.. Pedicelled spikelet 8–13 mm. long, including a white bearded callus 1–3 mm. long; lower glume glabrous to villous, usually pubescent; awn 4–10 cm. long, flexuous, plumose.. Fig. 163.
