HABIT Perennial; caespitose. Stolons present. Culms 30–40 cm long. Ligule an eciliate membrane; 1–1.5 mm long. Leaf-blades 3–8 cm long; 2–2.5 mm wide.

INFLORESCENCE Inflorescence a panicle.

Panicle open; ovate to globose; 15–25 cm long. Primary panicle branches spreading; simple; 5–15 cm long; bearing 1–3 fertile spikelets on each lower branch. Panicle branches stiff.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 4.5–6 mm long; falling entire.

GLUMES Glumes dissimilar; exceeding apex of florets; thinner than fertile lemma. Lower glume lanceolate; 1.1 length of upper glume; 1 length of spikelet; without keels; 7 -veined. Lower glume apex acute. Upper glume lanceolate; membranous; without keels; 7 -veined. Upper glume lateral veins ribbed. Upper glume surface pubescent; hairy between veins. Upper glume apex acute.

FLORETS Basal sterile florets barren; with palea. Lemma of lower sterile floret similar to upper glume; lanceolate; 0.9 length of spikelet; membranous; 7 -veined; ribbed; pubescent; hairy between veins; acute. Fertile lemma elliptic; 3–3.5 mm long; cartilaginous; shiny; 5–7 -veined. Lemma margins flat; covering most of palea. Lemma apex rostrate. Palea cartilaginous; without keels.
