HABIT Annual. Culms decumbent; 10–15 cm long; rooting from lower nodes. Culm-nodes pubescent. Leaf-sheaths outer margin hairy. Ligule a ciliate membrane. Leaf-blades lanceolate; 4–5 cm long; 7–12 mm wide; stiff. Leaf-blade midrib conspicuous. Leaf-blade surface pubescent; sparsely hairy; hairy abaxially, or on both sides; with tubercle-based hairs. Leaf-blade margins cartilaginous.

INFLORESCENCE Inflorescence a panicle.

Panicle open; ovate; 2.5–3.5 cm long; 1.5 cm wide. Primary panicle branches ascending, or spreading. Panicle branches with scattered hairs.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 2 fertile florets; without rhachilla extension. Spikelets orbicular; dorsally compressed; 2–2.5 mm long; breaking up at maturity; disarticulating above glumes but not between florets.

Lower glume surface pubescent. Lower glume apex obtuse. Upper glume orbicular; 2–2.5 mm long; 1.1 length of spikelet; membranous; without keels; 9 -veined. Upper glume surface pubescent. Upper glume apex obtuse.

FLORETS Fertile lemma ovate; 2–2.5 mm long; cartilaginous; without keel. Lemma margins involute. Lemma apex obtuse. Palea cartilaginous; 2 -veined.
