Perennial grass with long stolons, rooting and shooting at nodes, inflorescences narrow and nodding or drooping on long slender culms. A species of grasslands. Leaf-sheath 5–10 cm, with retrorse hairs 0.5 mm long, or glabrous; keeled. Auricles absent or minute, 0.15–0.25 mm long, scarcely clasping. Ligule 0.5–1 mm, lacerate; prominent. Leaf-blade 15–25 cm × 1.5–2 mm, flat, thin, abaxially with distinct midrib, glabrous or occasionally with hairs 1 mm long beside nerves or shortly retrorse prickle-toothed, adaxially with prickle teeth on nerves occasionally with hairs 0.5 mm long; margin glabrous or shortly toothed. Culm 50–75 cm, glabrous, slender, nodes inconspicuous. Inflorescence very narrow, slender, 8–15 cm, of 10–25 spikelets > internodes; internodes 2.5–6 mm below; rachis prolongation 3–6 mm. Spikelets 8–12 mm, of 1–2 florets, appearing shortly stipitate above glumes. Glumes 2, awnlike, 2–6 mm, ± equal, > internodes, 1-nerved, prickle-toothed on keel and margins, < spikelet. Lemma 6 .5–8 mm, glabrous except for prickle teeth towards bifid apex and evident on lateral nerves in upper half; keel ± prominent; scabrid awn 0.5–1 mm. Palea 6.5–7 mm, ≤ lemma; apex bifid; keels shortly toothed and inrolled. Callus 0 .5–0.75 mm, flat, almost glabrous; disarticulation almost flat. Rachilla to 1.3 mm if 2-flowered, shortly prickle-toothed; if 1-flowered rachilla prolongation 3–4 mm, shortly prickle-toothed. Lodicules 0.75–1.75 mm, lobed or entire. Anthers 1.6–2.6 mm, often retained on apex of caryopsis. Gynoecium: ovary 1–2 mm; stigma-styles 1 .75–2.25 mm. Caryopsis 4 mm; embryo 1–1.3.
