Tufted perennial; culms 30–150 cm. high, usually erect, the nodes yellowish to black and glabrous to bearded; basal leaf-sheaths usually becoming fibrous, typically woolly tomentose but sometimes silky pubescent to glabrescent.. Leaf-blades linear, flat or convolute, rarely filiform, 10–30 cm. long, 2–5 mm. wide.. Panicle linear to narrowly ovate, 10–30 cm. long, contracted or loose, the branches seldom markedly whorled.. Spikelets narrowly lanceolate, 8–13 mm. long, light to dark brown, mostly glabrous but sometimes setose from dark tubercles; lower glume ovate-elliptic, usually 1/3 as long as the spikelet and broadly obtuse but sometimes 1/2 as long and narrowly obtuse; upper glume lanceolate, as long as the spikelet, obtuse; lower lemma similar to the upper glume; upper lemma 4–7 mm. long, pubescent, acutely bidentate (lobes 0.2–1 mm. long); awn 2.5–5 cm. long; callus narrowly oblong, 0.8–1 mm. long, 2-toothed; stamens 2.. Fig. 114.
Tufted perennial 400-1500 mm high; basal leaf sheaths densely hairy, not woolly hairy, sometime silky pubescent to glabrescent, splitting into fibres; culm unbranched after first node. Leaf blade 100-300 x 5 mm, flat or convolute, rarely filiform; ligule a conspicuous fringe of hairs. Inflorescence linear to narrowly ovate, contracted or loose; branches and pedicels glabrous, scabrid or sometimes hairy. Spikelet 7-13 mm long; glumes glabrous or with few to many white hairs from rows of dark brown or black tubercles; lower glume usually 1/3-1/2 as long as upper glume, obtuse to truncate; upper glume as long as spikelet; lower lemma similar to upper lemma; upper lemma lobe 1 mm long, acute; central awn 25-50 mm long; callus of upper floret narrowly oblong, 2-toothed in mature specimens; stamens 2; anther 2.6-4.2 mm long.
Perennial; up to 1.5 m high; tufted. Culms erect. Leaf blades 100-300 x 5 mm; old lower sheaths fibrous. Flowers: in an open to contracted panicle; spikelets 7-13 mm long; lower glume obtuse or truncate; upper female-fertile lemma lobes acute; 1 mm long; central awn 25-50 mm long; callus of female-fertile floret clearly 2-toothed in mature specimens; stamens 2.
