HABIT Perennial; mat forming. Rhizomes elongated. Culms decumbent, or prostrate; 35–50 cm long; wiry. Culm-nodes glabrous. Leaf-sheaths glabrous on surface. Leaf-sheath oral hairs ciliate. Ligule an eciliate membrane; 1–1.6 mm long; lacerate. Leaf-blades ascending; flat, or conduplicate; 5–12 cm long; 1–3 mm wide.

INFLORESCENCE Inflorescence a panicle.

Panicle open; elliptic, or ovate; 5–10 cm long; 3–5 cm wide. Primary panicle branches spreading; 1–2 -nate; simple, or sparsely divided; bearing spikelets almost to the base.

Spikelets solitary, or in pairs. Fertile spikelets pedicelled. Pedicels unequal.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 3 mm long; falling entire. Spikelet callus glabrous; base obtuse.

Upper glume lanceolate; 3 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume apex acute.

FLORETS Fertile lemma oblong; 3 mm long; cartilaginous; without keel; 3 -veined. Lemma margins involute; interlocking with palea keels. Lemma apex acuminate; awned; 1 -awned. Principal lemma awn curved; 2–3 mm long overall. Palea with auriculate flaps; 1 length of lemma; cartilaginous; 2 -veined. Palea keels winged (below); narrowly winged.
