Ligule an eciliate membrane; 0.5–1.5 mm long; scaberulous on abaxial surface; lacerate; truncate, or acute. Leaf-blades spreading; curved; involute; 0.4–1.2 cm long; 0.2–0.4 mm wide. Leaf-blade surface ribbed; scabrous; rough adaxially. Leaf-blade margins scabrous. Leaf-blade apex obtuse.

INFLORESCENCE Inflorescence a panicle; shorter than basal leaves. Peduncle smooth.

Panicle capitate; ovate; 0.3–0.7 cm long. Panicle branches scaberulous.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels scaberulous.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 1.5–2 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus glabrous.

GLUMES Glumes persistent; similar; exceeding apex of florets; firmer than fertile lemma; gaping. Lower glume lanceolate; 1.5–2 mm long; 1 length of upper glume; membranous; much thinner on margins; 1-keeled; 1 -veined. Lower glume primary vein scabrous. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 1.5–2 mm long; membranous; with hyaline margins; 1-keeled; 1 -veined. Upper glume primary vein scabrous. Upper glume lateral veins absent. Upper glume apex acute.

FLORETS Fertile lemma ovate; 1.2–1.4 mm long; hyaline; without keel; 5 -veined. Lemma lateral veins obscure; extending close to apex. Lemma apex truncate; muticous. Palea 0.2–0.4 mm long; 0.2–0.25 length of lemma; hyaline.

FLOWER Lodicules 2; 0.2–0.3 mm long; membranous. Anthers 3; 0.4–0.6 mm long.
