HABIT Perennial. Culms decumbent; 20–50 cm long. Leaf-sheaths scaberulous. Ligule an eciliate membrane; 2–3 mm long. Leaf-blades 10–25 cm long; 10–15 mm wide. Leaf-blade surface scabrous; rough on both sides. Leaf-blade margins scabrous. Leaf-blade apex attenuate.

INFLORESCENCE Inflorescence a panicle.

Panicle open; ovate; effuse; 15–25 cm long. Primary panicle branches 5–7 -nate. Panicle branches capillary; scabrous.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; with a barren rhachilla extension. Spikelets lanceolate; laterally compressed; 2.5–2.8 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus glabrous; obtuse.

GLUMES Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma. Lower glume lanceolate; 1.5–1.7 mm long; 0.75 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume surface scabrous. Lower glume apex acute. Upper glume lanceolate; 2–2.4 mm long; 0.8 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume surface scabrous. Upper glume apex acute.

FLORETS Fertile lemma ovate; 2.5–2.8 mm long; cartilaginous; keeled; 5 -veined. Lemma surface scabrous; rough above. Lemma apex acute. Palea 1 length of lemma; 2 -veined. Palea keels approximate. Palea surface asperulous. Rhachilla extension 0.4 length of fertile floret.

FLOWER Anthers 3; 1.3 mm long.

DISTRIBUTION Asia-temperate: China and eastern Asia. Asia-tropical: India, Indo-China, and Malesia.
