Leaf-blade surface scaberulous; glabrous. Leaf-blade apex acuminate.
    Inflorescences
    Inflorescence a panicle; shorter than basal leaves; subtended by an inflated leaf-sheath; embraced at base by subtending leaf. Panicle spiciform; ovate; loose; 1-1.5 cm long; 0.6-0.8 cm wide. Primary panicle branches accrescent to a central axis; with evident branchlets on axis. Panicle axis with rounded ribs. Spikelets solitary. Fertile spikelets pedicelled. Pedicels oblong; glabrous.
    Spikelets

    Fertile
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; truncate; 3 mm long; 1.5 mm wide; falling entire.
    Glume
    Glumes free; similar; shorter than spikelet, or reaching apex of florets; recurved at apex. Lower glume oblong; 3 mm long; 1 length of upper glume; membranous; much thinner above; much thinner on margins; 1-keeled; 3 -veined. Lower glume primary vein ciliolate. Lower glume lateral veins distinct; convergent at apex. Lower glume surface hispidulous; hairy on veins. Lower glume apex obtuse. Upper glume oblong; 3 mm long; 0.9-1 length of adjacent fertile lemma; membranous; much thinner above; with hyaline margins; 1-keeled; 3 -veined. Upper glume primary vein ciliolate. Upper glume lateral veins convergent at apex. Upper glume surface hispidulous; hairy on veins. Upper glume apex obtuse.
    Florets
    Fertile lemma oblong; 3 mm long; membranous; keeled; 5 -veined. Lemma margins connate below; with 0.75-0.8 of their length connate. Lemma apex obtuse; awned; 1 -awned. Principal lemma awn dorsal; arising 0.5-0.6 way up back of lemma; straight; 1-1.5 mm long overall; not or scarcely exserted from spikelet. Palea absent or minute.
