Culm-sheaths persistent; auriculate. Culm-sheath blade lanceolate. Leaf-sheath auricles falcate. Ligule an eciliate membrane. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades lanceolate. Leaf-blade venation with obscure cross veins.
INFLORESCENCE Inflorescence a panicle.
Spikelets solitary. Fertile spikelets pedicelled.
FERTILE SPIKELETS Spikelets comprising 4–9 fertile florets; with diminished florets at the apex. Spikelets linear; subterete; 20–40 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite; pubescent. Floret callus pubescent.
GLUMES Glumes persistent; shorter than spikelet. Lower glume lanceolate; chartaceous; without keels; 5 -veined. Lower glume surface scabrous; without pits. Lower glume apex attenuate. Upper glume lanceolate; chartaceous; without keels; 5 -veined. Upper glume surface scabrous. Upper glume apex acuminate; awned; 1 -awned.
FLORETS Fertile lemma ovate; chartaceous; without keel; wingless; 5 -veined. Lemma lateral veins obscure. Lemma surface unwrinkled; without grooves; puberulous. Lemma margins ciliolate. Lemma apex awned; 1 -awned. Palea 1 length of lemma; chartaceous. Palea keels ciliolate. Apical sterile florets resembling fertile though underdeveloped.
