    Habit
    Annual. Culms robust; 60-120 cm long. Ligule a fringe of hairs. Leaf-blade base broadly rounded. Leaf-blades 10-60 cm long; 5-25 mm wide. Leaf-blade margins scabrous.
    Inflorescences
    Inflorescence composed of racemes. Racemes 3-15; borne along a central axis; unilateral; 2-8 cm long. Central inflorescence axis 5-15 cm long; tip without extension, or filiform. Rhachis broadly winged; 1-3 mm wide; ciliate on margins. Spikelet packing adaxial; regular; 2 -rowed. Spikelets solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; dorsally compressed; compressed slightly; acute; 4-6 mm long; falling entire. Rhachilla internodes elongated between glumes.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; dorsally compressed; compressed slightly; acute; 4-6 mm long; falling entire. Rhachilla internodes elongated between glumes.
    Glume

Lower glume apex acute, or acuminate. Upper glume oblong; 1 length of spikelet; membranous; without keels; 5-7 -veined. Upper glume surface pubescent; hairy above. Upper glume apex acute.
    Florets
    Basal sterile florets male; with palea. Lemma of lower sterile floret similar to upper glume; oblong; 1 length of spikelet; membranous; 5 -veined; pubescent; hairy above; acute. Fertile lemma elliptic; 3.5-5 mm long; indurate; without keel. Lemma surface granulose. Lemma margins involute. Lemma apex obtuse; mucronate. Palea involute; indurate; without keels.
