Tufted or open branched with long, stout, many-noded shoots; branching intra- and extravaginal and shooting and rooting at nodes; prophyll keels hairy. Leaf-sheath 3–12 cm, abaxially striate, glabrous, adaxially with minute prickles, margins membranous often terminated by small lobe. Ligule 0.2–0.3 mm, united to leaf-sheath margins. Collar thickened, curved, usually sparsely villous. Auricles usually absent but often 1 small (0.25 mm) or 1 large (1 mm) and clasping, occasionally with 1–2 long hairs. Leaf-blade 10–80 cm × 0.5–0.7 mm diam., filiform, abaxially glaucous, ribbed, adaxially and on margin with dense weft of 1 mm hairs at base, often projecting, becoming shorter and less dense above. Culm 15–40 cm, erect, internodes glabrous. Inflorescence 5–20 cm, of up to 8 spikelets. Spikelets 40–60 mm, of 6–8 florets. Glumes unequal, usually produced into prickle-toothed awn up to 3 mm; lower 4.5–6.5 mm, 3–5-nerved, upper 7–11 mm, 5–7-nerved. Lemma with central nerve prominent and extending into recurved awn 25–60 mm, smooth except for prickle-teeth at base of awn and on margins. Palea 10–11.5 mm, apex pointed and bifid.
