HABIT Perennial. Culms prostrate; 30–60 cm long. Leaves cauline. Leaf-sheaths glabrous on surface. Ligule an eciliate membrane; lacerate. Leaf-blades 10–15 cm long; 8–12 mm wide. Leaf-blade surface glabrous. Leaf-blade margins scaberulous. Leaf-blade apex acuminate.

INFLORESCENCE Inflorescence a panicle; embraced at base by subtending leaf.

Panicle open; ovate; effuse; 20 cm long. Primary panicle branches sparsely divided. Panicle axis scaberulous. Panicle branches capillary; scaberulous.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels tip cupuliform.

Lower glume apex acute. Upper glume ovate; 1 length of spikelet; membranous; without keels; 5 -veined. Upper glume apex acuminate.

FLORETS Basal sterile florets male; with palea. Lemma of lower sterile floret similar to upper glume; ovate; 1 length of spikelet; membranous; 7 -veined; acute. Palea of lower sterile floret 1 length of lemma. Fertile lemma ovate; dorsally compressed; 3 mm long; indurate; dark brown; without keel. Lemma surface striate. Lemma margins involute. Lemma apex acute, or acuminate. Palea involute; indurate.
