Branch complement several, or many. Leaf-sheaths mostly shorter than adjacent culm internode; keeled (above). Leaf-sheath oral hairs lacking, or ciliate. Leaf-sheath auricles erect. Ligule an eciliate membrane; 3 mm long. Collar with external ligule. Leaf-blade base broadly rounded; asymmetrical; with a brief petiole-like connection to sheath; petiole 0.2-0.3 cm long; petiole pilose. Leaf-blades deciduous at the ligule; lanceolate, or oblong; 9-13 cm long; 12-27 mm wide. Leaf-blade venation with obscure cross veins. Leaf-blade surface glabrous. Leaf-blade margins scabrous.

    Spikelets
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; acuminate; 9-10 mm long; 2 mm wide; breaking up at maturity; disarticulating below each fertile floret.
    Fertile
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; acuminate; 9-10 mm long; 2 mm wide; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma. Lower glume orbicular; 0.2-0.5 mm long; 1 length of upper glume; membranous; without keels. Lower glume apex obtuse. Upper glume orbicular; 0.02-0.05 length of adjacent fertile lemma; without keels. Upper glume apex obtuse.
    Florets

Lemma of upper sterile floret ovate; 5 mm long; chartaceous; acute. Fertile lemma oblong; 9-10 mm long; coriaceous; without keel. Lemma apex acute. Palea 1 length of lemma. Palea apex emarginate.
