Ligule an eciliate membrane; 0.5-1 mm long; truncate. Leaf-blades 6-20 cm long; 3-8 mm wide. Leaf-blade surface scaberulous; rough on both sides; glabrous, or pubescent; sparsely hairy; hairy adaxially. Leaf-blade apex acute.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; arcuate; bilateral; 8-18 cm long. Rhachis flattened; pubescent on surface (sparsely); ciliate on margins. Spikelet packing broadside to rhachis. Rhachis internodes oblong; 5-8 mm long. Spikelets in pairs. Fertile spikelets sessile; 2 in the cluster.
    Spikelets
    Spikelets comprising 4-5 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 10-13 mm long; 2-3 mm wide; breaking up at maturity; disarticulating below each fertile floret. Spikelet callus glabrous; base truncate. Rhachilla internodes 1.5-2 mm long; pubescent.
    Fertile
    Spikelets comprising 4-5 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 10-13 mm long; 2-3 mm wide; breaking up at maturity; disarticulating below each fertile floret. Spikelet callus glabrous; base truncate. Rhachilla internodes 1.5-2 mm long; pubescent.
    Glume
    Glumes collateral; persistent; similar; shorter than spikelet. Lower glume lanceolate; 4-5 mm long; 1 length of upper glume; coriaceous; without keels; 3-7 -veined. Lower glume lateral veins ribbed. Lower glume surface scabrous. Lower glume apex acuminate; awned; 1 -awned. Lower glume awn 4-6 mm long. Upper glume lanceolate; 4-5 mm long; 0.4-0.5 length of adjacent fertile lemma; coriaceous; without keels; 3-5 -veined. Upper glume lateral veins ribbed. Upper glume surface scabrous. Upper glume apex acuminate; awned; 1 -awned. Upper glume awn 4-6 mm long.
    Florets
    Fertile lemma lanceolate; 8-11 mm long; coriaceous; without keel; 5 -veined. Lemma surface scabrous; rough on veins; glabrous, or puberulous. Lemma apex acute; awned; 1 -awned. Principal lemma awn flexuous; 15-18 mm long overall. Palea 2 -veined. Palea keels ciliolate. Palea surface glabrous, or pubescent; hairy on back. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; membranous. Anthers 3; 1.5-2 mm long. Stigmas 2; protandrous; laterally exserted. Ovary pubescent on apex.
