    Habit
    Annual. Culms erect; 40-90 cm long; 2-5 -noded. Culm-nodes glabrous. Leaf-sheaths glabrous on surface, or pubescent; outer margin glabrous, or hairy. Ligule a ciliate membrane; 0.8-1.5 mm long. Leaf-blades 4-30 cm long; 3-9 mm wide. Leaf-blade surface smooth, or scabrous; glabrous, or pilose. Leaf-blade margins scabrous; glabrous, or ciliate; hairy at base.
    Inflorescences
    Inflorescence a panicle. Panicle open; ovate; 15-30 cm long; evenly furnished, or with spikelets clustered towards branch tips. Primary panicle branches spreading; 10-25 cm long; bearing 20-60 fertile spikelets on each lower branch. Panicle axis scabrous. Panicle branches scabrous; glabrous in axils. Spikelets solitary. Fertile spikelets pedicelled. Pedicels 1-7 mm long; scabrous.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate, or elliptic; dorsally compressed; 3.1-3.7 mm long; 1-1.8 mm wide; falling entire. Rhachilla internodes elongated between glumes. Rhachilla elongation 0.4-0.5 mm long.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate, or elliptic; dorsally compressed; 3.1-3.7 mm long; 1-1.8 mm wide; falling entire. Rhachilla internodes elongated between glumes. Rhachilla elongation 0.4-0.5 mm long.
    Glume
    Glumes reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate, or ovate; 2.3-3.3 mm long; 0.75-0.95 length of spikelet; membranous; without keels; 3-5 -veined. Lower glume lateral veins thickened. Lower glume apex acute, or acuminate. Upper glume lanceolate, or ovate; 1 length of spikelet; membranous; without keels; 7 -veined. Upper glume apex obtuse, or acute, or acuminate.
    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret similar to upper glume; lanceolate, or ovate; 1 length of spikelet; membranous; 5 -veined; acute, or acuminate. Fertile lemma elliptic; dorsally compressed; 1.9-2.2 mm long; indurate; without keel. Lemma lateral veins distinct. Lemma margins involute. Lemma apex obtuse. Palea involute; indurate.
    Flowers
    Anthers 3; 1.2-1.4 mm long.
    Fruits
