Leaf-sheaths tubular for much of their length; with 1 of their length closed; 3–4.5 cm long; puberulous. Ligule an eciliate membrane. Collar pubescent. Leaf-blades filiform; conduplicate; elliptic in section, or circular in section; 15–23 cm long; 0.5–0.65 mm wide. Leaf-blade venation comprising (5–)7 vascular bundles; with 3 inner ridges; with unevenly thickened subepidermal sclerenchyma layer on the underside, or with continuous uniform subepidermal sclerenchyma layer on the underside. Leaf-blade surface pilose; hairy abaxially.

INFLORESCENCE Inflorescence a panicle.

Panicle open; loose; 6–7 cm long. Panicle axis scabrous. Panicle branches scabrous.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 4–5 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 7–8 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; chartaceous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; chartaceous; without keels; 3 -veined. Upper glume apex acuminate.

FLORETS Fertile lemma oblong; 4.5–5.5 mm long; chartaceous; without keel; 5 -veined. Lemma apex acuminate; awned; 1 -awned. Principal lemma awn (1.9–)2.5–3.5 mm long overall. Palea 2 -veined. Palea keels scaberulous; adorned above; with 0.33 of their length adorned. Apical sterile florets resembling fertile though underdeveloped.
