Habit
Annual, tufted. Culms geniculately ascending or decumbent, 15–90 cm tall. Mid-culm nodes brown. Leaf-sheaths 5.5–10 cm long, glabrous on surface. Ligule a fringed membrane, 0.3–1 mm long. Leaf-blades 3–30 cm long, 1.2–4.5 mm wide. Leaf-blade surface glabrous. Leaf-blade margins scaberulous.

Inflorescence
Inflorescence solid, a panicle. Panicle spiciform, linear, 2–12 cm long, 0.3–0.5 cm wide. Primary panicle branches accrescent to a central axis, with lateral stumps on axis. Panicle axis with rounded ribs.

Spikelets
Spikelets solitary. Pedicels scabrous. Fertile spikelets 2-flowered, comprising 1 fertile floret, lower floret sterile or male, upper fertile, without rhachilla extension, elliptic or ovate, laterally compressed, gibbous, obtuse, 1.1–1.9 mm long, 0.55–0.7 mm wide, falling entire.

Glumes
Glumes thinner than fertile lemma. Lower glume ovate, clasping, 0.6–1 mm long, 50% of length of spikelet, membranous, 3–5-nerved. Lower glume apex acute. Upper glume elliptic, gibbous, 1.1–1.5 mm long, 150% of length of adjacent fertile lemma, 100% of length of spikelet, membranous, with hyaline margins, 7–9-nerved. Upper glume lateral nerves ribbed. Upper glume surface glabrous. Upper glume apex obtuse.

Florets
Basal sterile floret 1, with palea. Lemma of lower sterile floret similar to upper glume, elliptic, 1.1–1.5 mm long, 100% of length of spikelet, membranous, 7-nerved, ribbed, glabrous, obtuse. Fertile lemma elliptic, dorsally compressed, 1–1.3 mm long, coriaceous, glossy, 5-nerved. Lemma margins involute. Lemma apex acute. Palea involute, coriaceous. Anthers 3, 0.6 mm long.
