HABIT Perennial. Cataphylls evident. Basal innovations extravaginal. Culms decumbent; 20–40 cm long; rooting from lower nodes. Leaf-sheaths smooth. Ligule an eciliate membrane; 1.25–2 mm long; truncate. Leaf-blades 10–17.5 cm long; 4–5 mm wide. Leaf-blade surface scabrous.

INFLORESCENCE Inflorescence a panicle.

Panicle contracted; linear; 4–9 cm long; 0.6–1.5 cm wide. Primary panicle branches appressed; naked below, or bearing spikelets almost to the base. Panicle branches scabrous.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 1.65–1.85 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; shiny; gaping. Lower glume elliptic; 1.65–1.85 mm long; 1.1 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume elliptic; 1.4–1.5 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume apex acute.

FLORETS Fertile lemma oblong; 1.5–1.6 mm long; hyaline; without keel; 5 -veined. Lemma lateral veins obscure; extending close to apex. Lemma apex entire; acute; muticous. Palea 0.5 mm long; 0.33 length of lemma; hyaline.

FLOWER Lodicules 2; membranous. Anthers 3; 0.8–0.9 mm long.

FRUIT Caryopsis with adherent pericarp. Hilum linear.

DISTRIBUTION Asia-tropical: Malesia.
