Leaf-blade venation with 6–10 secondary veins; with distinct cross veins. Leaf-blade surface glabrous. Leaf-blade margins scaberulous. Leaf-blade apex acuminate.

INFLORESCENCE Synflorescence compound; with principal spatheoles embracing a compact fascicle of racemes, each subtended by a subsidiary bract. Inflorescence composed of racemes; subtended by a spatheole; embraced at base by subtending leaf.

Racemes 1; single.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels 4–10 mm long; pubescent.

FERTILE SPIKELETS Spikelets comprising 3–4 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 25–30 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 4–6 mm long; pubescent. Floret callus pilose. Floret callus hairs 1–1.5 mm long.

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 10–14 mm long; chartaceous; without keels. Lower glume surface puberulous. Lower glume apex cuspidate. Upper glume lanceolate; 18–26 mm long; chartaceous; without keels; 7–9 -veined. Upper glume apex cuspidate.

FLORETS Fertile lemma lanceolate; 16–25 mm long; chartaceous; without keel; 9–13 -veined. Lemma surface puberulous; hairy above. Lemma margins eciliate, or ciliolate. Lemma apex cuspidate. Palea 11–15 mm long. Palea keels ciliate; adorned above. Palea surface puberulous; hairy on back. Apical sterile florets resembling fertile though underdeveloped.
