HABIT Annual; caespitose. Culms 10–75 cm long. Culm-internodes smooth. Lateral branches lacking. Leaf-sheaths loose; smooth; glabrous on surface. Ligule an eciliate membrane; 3–4.5 mm long; scaberulous on abaxial surface; obtuse. Leaf-blades flat, or conduplicate; 3–6 cm long; 1–2 mm wide. Leaf-blade surface scabrous; rough on both sides; glabrous. Leaf-blade apex acute.

INFLORESCENCE Inflorescence a panicle.

Panicle open; ovate; 5–9 cm long; 3–4 cm wide. Primary panicle branches spreading. Panicle branches scabrous.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels scabrous.

FERTILE SPIKELETS Spikelets comprising 2–3 fertile florets; with a barren rhachilla extension. Spikelets oblong; laterally compressed; 4 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus glabrous.

Lower glume apex attenuate, or setaceously attenuate. Upper glume elliptic; 3 mm long; 0.9 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume primary vein scabrous. Upper glume apex acuminate.

FLORETS Fertile lemma oblong; elliptic in profile; 3–3.5 mm long; membranous; keeled; keeled above; 5 -veined. Lemma midvein scabrous; ciliate; hairy below. Lemma surface pubescent; hairy below; hairy on veins. Lemma apex obtuse. Palea keels scaberulous; adorned above. Palea surface scabrous.

FLOWER Lodicules 2; membranous. Anthers 3; 2 mm long.
