Leaf-blades lanceolate; 13.4-29.5 cm long; 23-42 mm wide. Leaf-blade venation with distinct cross veins. Leaf-blade surface smooth, or scaberulous; rough adaxially; glabrous, or pilose; hairy abaxially.
    Inflorescences
    Inflorescence a panicle; embraced at base by subtending leaf. Panicle open; ovate; secund; 6-16 cm long; contracted about primary branches. Primary panicle branches spreading; 4-15 cm long. Panicle axis angular; pubescent. Panicle branches angular; pubescent. Spikelets solitary. Fertile spikelets pedicelled. Pedicels angular; 2-7 mm long; pubescent.
    Spikelets
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 6.2-9 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Fertile
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 6.2-9 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 0.5-1.1 mm long; membranous; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume ovate; 0.8-2 mm long; 0.1-0.2 length of adjacent fertile lemma; membranous; without keels; 1 -veined. Upper glume lateral veins absent. Upper glume apex obtuse, or acute.

    Basal sterile florets barren; without significant palea; attached to and deciduous with the fertile. Lemma of lower sterile floret ovate; 3.6-5.6 mm long; 0.5 length of fertile lemma; chartaceous; 3-7 -veined; pubescent; hairy above; ciliolate on margins; fringed above; acute. Lemma of upper sterile floret ovate; 4.3-6.5 mm long; chartaceous; pilose; ciliate on margins; acute. Fertile lemma ovate; 6.1-8 mm long; coriaceous; without keel; 7-9 -veined. Lemma surface pubescent; hairy above. Lemma margins ciliolate; hairy above. Lemma apex apiculate. Palea 6.2-7.8 mm long; 2-4 -veined. Palea surface scabrous.
