Habit
Perennial, tufted. Stolons present. Culms 20–40 cm tall. Lateral branches sparsely branched. Leaf-sheath auricles present. Ligule an eciliate membrane, 0.8–1.5 mm long. Leaf-blades flat, 3–15 cm long, 2–4.5 mm wide. Leaf-blade surface smooth.

Inflorescence
Inflorescence compound, a panicle. Panicle open, ovate to globose, 8–25 cm long, 0.25–0.35 cm wide. Primary panicle branches spreading, simple, 5–15 cm long, bearing 1–3 fertile spikelets on each lower branch. Panicle branches stiff.

Spikelets
Spikelets solitary. Fertile spikelets 2-flowered, comprising 1 fertile floret, lower floret sterile, upper fertile, without rhachilla extension, lanceolate, dorsally compressed, 4.5–6.1 mm long, falling entire.

Glumes
Glumes dissimilar, thinner than fertile lemma. Lower glume lanceolate, 4.8–6.1 mm long, 110% length of upper glume, 100% of length of spikelet, 7-nerved. Lower glume apex acute. Upper glume lanceolate, 4.5–5.7 mm long, membranous, 7-nerved. Upper glume lateral nerves ribbed. Upper glume surface pubescent, hairy between nerves. Upper glume apex acute or acuminate.

Florets
Basal sterile floret 1, with palea. Lemma of lower sterile floret similar to upper glume, lanceolate, 4.2–5.5 mm long, 900% of length of spikelet, membranous, 7-nerved, ribbed, pubescent, hairy between nerves, acute or acuminate. Fertile lemma elliptic, 2–3.5 mm long, cartilaginous, of similar consistency on margins, yellow, glossy, 5–7-nerved. Lemma margins flat, covering most of palea. Lemma apex rostrate, muticous or mucronate. Palea cartilaginous, without keels. Anthers 1.3–1.7 mm long.
