    Habit
    Perennial. Rhizomes elongated. Butt sheaths persistent and investing base of culm; with fibrous dead sheaths. Culms geniculately ascending; 40-70 cm long; 2-3 -noded. Leaf-sheaths glabrous on surface, or puberulous. Ligule an eciliate membrane; 0.5-1 mm long. Leaf-blades flat, or convolute; 20-30 cm long; 5-8 mm wide; glaucous. Leaf-blade surface scabrous; rough adaxially; glabrous. Leaf-blade apex acuminate.
    Inflorescences
    Inflorescence composed of racemes; embraced at base by subtending leaf. Racemes 1; single; bilateral; 7-20 cm long. Rhachis ciliate on margins. Spikelet packing broadside to rhachis. Rhachis internodes linear; 5-6 mm long. Rhachis internode tip flat. Spikelets solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 3-7 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 12-21 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pubescent.
    Fertile
    Spikelets comprising 3-7 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 12-21 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pubescent.
    Glume
    Glumes collateral; persistent; similar; shorter than spikelet. Lower glume lanceolate; asymmetrical; 8-15 mm long; 0.9 length of upper glume; coriaceous; much thinner on margins; without keels; 4-7 -veined. Lower glume lateral veins ribbed. Lower glume surface scabrous. Lower glume apex entire, or dentate; 2 -fid; acute; mucronate. Upper glume lanceolate; asymmetrical; 9-17 mm long; 0.75 length of adjacent fertile lemma; coriaceous; with scarious margins; without keels; 4-7 -veined. Upper glume lateral veins ribbed. Upper glume surface scabrous; rough above. Upper glume apex entire, or dentate; 2 -fid; acute; mucronate.
    Florets
    Fertile lemma lanceolate; 10-18 mm long; coriaceous; 5-7 -veined. Lemma surface puberulous. Lemma apex dentate; 2 -fid; acute; mucronate, or awned; 1 -awned. Principal lemma awn from a sinus; 1-5 mm long overall. Palea 1 length of lemma. Palea keels ciliate. Palea surface pubescent; hairy on back. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; membranous. Anthers 3; 2-2.5 mm long. Stigmas 2. Ovary pubescent on apex.
    Fruits
    Caryopsis with adherent pericarp; 6-7 mm long.
