Tufted perennial, 1-2 m high; short rhizomatous; fresh shoots not aromatic. Leaf blade up to 400 x 5 mm; ligule an unfringed membrane. Inflorescence of paired racemes enclosed by spatheoles, crowded into large, leafy, false panicle; raceme pairs with 6-10 awns; raceme bases unequal, terete, with 1 homogamous pair at base of upper racemes or absent; racemes deflexed at maturity. Sessile spikelets 4.5-5.5 mm long, dorsiventrally compressed, white-pubescent to villous. Florets 2; lower floret sterile, reduced to a lemma, awnless; upper floret bisexual, lemma less firm than glumes towards base, hyaline, 2-lobed; awns 18-36 mm long; callus slender, 0.7-1.2 mm long, tip visible on apex of internode. Pedicellate spikelets 5-7 mm long, awnless. Flowering time Jan.-June.
False panicle c. 30 cm long, narrow, moderately dense; spatheoles 3–5 cm long, linear, russet coloured; peduncles flexuous, a little longer than the spatheoles, with spreading white tubercle-based hairs above; racemes 1.5–2 cm long, 6–10-awned per pair, white-hirsute, terminally exserted, at least some of them deflexed; internodes 2–3 mm long; raceme-bases unequal, the superior 2–3.5 mm long, hirsute, sometimes with a few stiff bristles or sometimes glabrous.
Tufted perennial 1 000-2 000 mm high; shortly rhizomatous. Leaf blade to 400 x to 5 mm. Raceme bases unequal, terete, with 0 or 1 homogamous pairs at base of upper raceme; raceme deflexed at maturity; raceme pairs with 6-10 awns. Sessile spikelet 4.5-5.5 mm long, white pubescent to villous; awn 18-36 mm long; callus slender, 0.7-1.2 mm long. Pedicellate spikelet 5-7 mm long, pubescent to villous, acute; anther 1.7-2.3 mm long.
Perennial; up to 2 m high; shortly rhizomatous and tufted. Culms erect. Leaf blades up to 400 x 5 mm.
