Wiry, tufted perennial, 300-800 mm high; rhizomatous; culms slender; fresh shoots not aromatic. Leaf blade 20-150 x 1-2(-4)mm; ligule an unfringed membrane. Inflorescence of 2-10 raceme pairs, racemes enclosed by spatheoles, crowded into large, leafy, false panicle, panicle scanty; raceme pairs with 8-14 awns; raceme bases terete, unequal; racemes never deflexed; spikelets in pairs, one sessile, the other pedicelled, with 1 homogamous pair at base of upper racemes or absent. Sessile spikelets 4.0-6.5 mm long, dorsiventrally compressed, yellowish green to violet, white-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 10-35 mm long, with hairs up to 0.3 mm long; callus acute, tip visible on apex of internode. Pedicellate spikelets 3-7 mm long, awnless. Flowering time Sept.-June.
False panicle up to 30 cm long, typically scanty with only 2–10 raceme-pairs but sometimes a little fuller with more raceme-pairs; spatheoles 3–8 cm long, linear-lanceolate, at length reddish; peduncles about as long as the spatheoles, glabrous or with white bulbous-based hairs above; racemes 2–4 cm long, 8–13(16)-awned per pair, white-villous, terminally exserted, never deflexed; raceme-bases unequal, the superior 2.5–5 mm long, filiform, glabrous or more usually pubescent to hirsute, with or without a white beard at the foot.

Perennial, rhizomatous and tufted (wiry), up to 0.8 m high. Leaf blades 20-150 mm long, 1-2(-4) mm wide. Culms slender. Spikelets (sessile) 4.0-6.5 mm long (yellowish green to violet, white-villous, callus acute). Panicle scanty, of 2-10 raceme pairs, the pairs with 0 or 1 homogamous pairs at base of upper racemes and 8-14 awns 10-35 mm long with hairs to 0.3 mm long; raceme bases terete, unequal; racemes never deflexed, 20-40 mm long.
Perennial, up to 2 m tall. Leaves linear, 1-2 mm wide; ligule an unfringed membrane. Inflorescence a leafy false panicle of paired, white hairy racemes 20-40 mm long, never deflexed, subtended by spathes, raceme pairs with 8-14 awns, spikelets paired in sessile and pedicellate combination of dissimilar spikelets. Sessile spikelets 4-6.5 mm long; awn 10-30 mm long, hairy. Pedicelled spikelets 3-7 mm long, sterile, awnless.
Sessile spikelets 4–6.5 mm long; callus 0.5–1.5 mm long, subacute to acute; inferior glume linear-elliptic, yellowish-green to violet, white-villous but occasionally the hairs rather sparse; awn 10–35 mm long, puberulous with white hairs 0.1–0.3 mm long.
