HABIT Perennial; caespitose. Culms geniculately ascending; 35–70 cm long; 3–5 -noded. Culm-internodes smooth. Leaf-sheaths smooth; glabrous on surface. Ligule an eciliate membrane; 2.5–4.5 mm long; lacerate; obtuse. Leaf-blades flat; 5–17 cm long; 1–2.5 mm wide. Leaf-blade surface scabrous.

INFLORESCENCE Inflorescence a panicle.

Panicle open; elliptic, or ovate; effuse; 10–20 cm long; 2–8 cm wide. Primary panicle branches 2–6 -nate; whorled at most nodes. Panicle axis scabrous.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels 1–7 mm long; 1.1–1.4 length of fertile spikelet.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 1.4–1.8 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent.

GLUMES Glumes persistent; similar; exceeding apex of florets; firmer than fertile lemma; shiny; gaping. Lower glume lanceolate; 1.4–1.8 mm long; 1 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein scabrous. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 1.4–1.8 mm long; 1.4–1.5 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume primary vein scabrous. Upper glume lateral veins absent. Upper glume apex acute.

FLORETS Fertile lemma elliptic; 0.9–1.3 mm long; hyaline; without keel; 5 -veined. Lemma lateral veins extending close to apex. Lemma apex erose; truncate; muticous. Palea 0.7–0.8 mm long; 0.6–0.75 length of lemma; hyaline. Palea apex erose.

FLOWER Lodicules 2; membranous. Anthers 3; 0.9–1.2 mm long.

FRUIT Caryopsis with adherent pericarp; 1 mm long. Hilum linear.
