    Perennial. Culms geniculately ascending; 50-120 cm long; 3-5 -noded. Culm-nodes glabrous. Leaf-sheath auricles falcate; 0.5 mm long. Ligule an eciliate membrane. Leaf-blades flat, or convolute; 10-20 cm long; 2-6 mm wide; stiff. Leaf-blade surface scabrous; rough adaxially.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; bilateral; 5-20 cm long. Spikelet packing broadside to rhachis. Rhachis internodes linear; 2-5 mm long. Rhachis internode tip flat. Spikelets solitary, or in pairs. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 3-6 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 12 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pilose.
    Fertile
    Spikelets comprising 3-6 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 12 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pilose.
    Glume
    Glumes collateral; persistent; similar; shorter than spikelet. Lower glume lanceolate; symmetrical; 7-8 mm long; 1 length of upper glume; coriaceous; without keels; 3-5 -veined. Lower glume lateral veins ribbed. Lower glume surface scabrous; rough on veins. Lower glume apex acute; awned; 1 -awned. Lower glume awn 1-4 mm long. Upper glume lanceolate; symmetrical; 7-8 mm long; 1 length of adjacent fertile lemma; 0.75 length of spikelet; coriaceous; without keels; 3-5 -veined. Upper glume lateral veins ribbed. Upper glume surface scabrous. Upper glume apex acute; awned; 1 -awned. Upper glume awn 1-4 mm long.
    Florets
    Fertile lemma lanceolate; 9-10 mm long; coriaceous; 5-7 -veined. Lemma surface scabrous. Lemma apex acute; awned; 1 -awned. Principal lemma awn 1.3-5 mm long overall. Palea 1 length of lemma. Palea keels ciliolate. Apical sterile florets resembling fertile though underdeveloped.
