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. Rachilla 2–3 mm, hairy. Callus 1–1.5 mm heavily bearded, hairs 1.5–2.5 mm ≥ callus. Lodicules 1.5–2 mm. Anthers 3.8–5.5 mm. Gynoecium: ovary 1.5 mm; stigma-styles 2.5–3.5 mm.
