    Leaf-blades lanceolate, 3–12 cm. long, 5–20 mm. wide, broadly rounded at the base, mostly glabrous on the margins (ciliate in India).
    Inflorescences
    Inflorescence of 2–8 racemes on a common axis 1–7 cm. long; racemes 2–5 cm. long, bearing single or paired spikelets on a subtriquetrous rhachis, the pedicels (sometimes also the rhachis) with white hairs.
    Spikelets
    Spikelets narrowly ovate, 3–4(–4.5) mm. long, sharply acute; lower glume ovate, 1/3 the length of the spikelet, subacute; upper glume without crossveins, glabrous or pubescent; upper lemma submuricate with a mucro 0.5 mm. long (merely mucronulate in India).

    Habit
    Annual. Culms 100-120 cm long. Culm-internodes distally pubescent. Culm-nodes bearded. Leaf-sheaths mostly shorter than adjacent culm internode; pubescent; with tubercle-based hairs. Ligule a fringe of hairs; 1-2 mm long. Leaf-blade base cordate, or amplexicaul. Leaf-blades lanceolate, or ovate; 8-15 cm long; 18-24 mm wide. Leaf-blade surface pubescent; densely hairy; hairy on both sides. Leaf-blade margins scabrous; ciliate; hairy all along (at least to middle).
    Inflorescences
    Inflorescence composed of racemes. Peduncle pubescent above. Racemes 6-12; borne along a central axis; unilateral; 1.5-4 cm long. Central inflorescence axis 6-13 cm long. Rhachis wingless; angular; ciliate on margins. Spikelets in pairs. Fertile spikelets sessile and pedicelled. Pedicels ciliate.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic, or ovate; dorsally compressed; acuminate; 4-5 mm long; falling entire.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic, or ovate; dorsally compressed; acuminate; 4-5 mm long; falling entire.
    Glume
    Glumes dissimilar; reaching apex of florets; thinner than fertile lemma. Lower glume ovate; 0.2 length of spikelet; membranous; without keels. Lower glume apex obtuse. Upper glume ovate; 1 length of spikelet; herbaceous; without keels; 7 -veined. Upper glume surface pubescent. Upper glume apex acute.
    Florets
    Basal sterile florets male, or barren; with palea. Lemma of lower sterile floret similar to upper glume; ovate; 0.9 length of spikelet; herbaceous; 5-7 -veined; pubescent; acute. Fertile lemma elliptic; 2 mm long; indurate; without keel. Lemma surface rugulose. Lemma margins involute. Lemma apex mucronate. Principal lemma awn 0.1 mm long overall. Palea involute; indurate; without keels.
