Culm-sheath blade triangular; acute. Leaf-sheaths keeled; pilose. Ligule a ciliate membrane. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades lanceolate; 12–40 cm long; 17–25 mm wide. Leaf-blade midrib prominent beneath. Leaf-blade venation with 12–14 secondary veins. Leaf-blade surface pubescent; hairy on both sides. Leaf-blade margins scabrous. Leaf-blade apex acuminate.

INFLORESCENCE Synflorescence bractiferous; clustered at the nodes; in globose clusters; dense; 4–5 cm between clusters; with glumaceous subtending bracts; with axillary buds at base of spikelet; prophyllate below lateral spikelets; leafless between clusters.

Fertile spikelets sessile.

FERTILE SPIKELETS Spikelets comprising 2–3 fertile florets; without rhachilla extension. Spikelets ovate; laterally compressed; 7.5–10 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes suppressed between florets.

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume ovate; chartaceous; without keels. Lower glume surface pubescent. Lower glume margins ciliate. Lower glume apex acute. Upper glume ovate; chartaceous; without keels. Upper glume surface pubescent. Upper glume margins ciliate. Upper glume apex acuminate.

FLORETS Fertile lemma ovate; 7.5–9 mm long; chartaceous; without keel. Lemma surface pubescent; hairy above. Lemma apex attenuate; pungent. Palea chartaceous; 5 -veined; 2-keeled but the uppermost without keels. Palea keels ciliate. Palea surface pubescent; hairy on flanks.

FLOWER Lodicules absent. Anthers 6; yellow; anther tip apiculate, or penicillate. Filaments united in a tube. Stigmas 1; pubescent. Ovary umbonate; pubescent all over.

FRUIT Caryopsis with adherent pericarp.
