Leaf-blade apex attenuate.
INFLORESCENCE Inflorescence a panicle.
Panicle contracted; linear; 3–10 cm long.
Spikelets solitary. Fertile spikelets pedicelled.
FERTILE SPIKELETS Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; 6 mm long; breaking up at maturity; disarticulating below each fertile floret.

Lower glume awn 2 mm long. Upper glume lanceolate; 2 mm long; 0.33 length of adjacent fertile lemma; membranous; without keels. Upper glume apex acuminate; awned; 1 -awned. Upper glume awn 2 mm long.
FLORETS Basal sterile florets barren; without significant palea; attached to and deciduous with the fertile. Lemma of lower sterile floret ovate; 2.5–3 mm long; 0.5 length of fertile lemma; chartaceous; acute; awned. Awn of lower sterile floret 1 mm long. Lemma of upper sterile floret ovate; 3 mm long; chartaceous; acute; awned. Awn of upper sterile floret 1 mm long. Fertile lemma ovate; 6 mm long; coriaceous; without keel; 5 -veined. Lemma margins pubescent. Lemma apex acute.
