HABIT Annual; caespitose. Culms 18–50 cm long. Ligule an eciliate membrane; 0.3–1.2 mm long. Leaf-blades 9–15 cm long; 3–5 mm wide.

INFLORESCENCE Inflorescence a panicle. Peduncle 7–17 cm long.

Panicle spiciform; linear; 2–6 cm long; 0.5–0.7 cm wide. Primary panicle branches accrescent to a central axis; with lateral stumps on axis. Panicle axis with rounded ribs.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels scabrous.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; laterally compressed; gibbous; 2.5–3.3 mm long; falling entire.

GLUMES Glumes reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate, or elliptic; 1.5–2.2 mm long; 0.5–0.66 length of spikelet; hyaline; without keels; 5–7 -veined. Lower glume apex obtuse, or acute. Upper glume lanceolate, or ovate; gibbous; 1 length of spikelet; membranous; without keels; 11–13 -veined. Upper glume lateral veins ribbed. Upper glume margins ciliate. Upper glume apex acute.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret similar to upper glume; lanceolate, or ovate; 1 length of spikelet; membranous; 9 -veined; ribbed; eciliate on margins, or ciliolate on margins; acute. Fertile lemma elliptic; dorsally compressed; 1.1–1.5 mm long; coriaceous; shiny; without keel. Lemma margins involute. Lemma apex acute. Palea involute; coriaceous.
