    Habit
    Perennial; caespitose. Butt sheaths pubescent. Culms 30-90 cm long; 1-4 -noded. Culm-nodes pubescent. Leaf-sheaths glabrous on surface; outer margin glabrous. Leaf-sheath oral hairs lacking. Leaf-sheath auricles falcate. Ligule an eciliate membrane; 0.2-1 mm long; lacerate. Leaf-blades 6.5-11 cm long; 2.5-4 mm wide. Leaf-blade surface scabrous; rough on both sides; glabrous, or pilose; sparsely hairy; hairy adaxially. Leaf-blade margins scabrous.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; straight, or arcuate; bilateral; 8-12.5 cm long. Rhachis flattened; scaberulous on margins; ciliate on margins. Spikelet packing broadside to rhachis. Rhachis internodes linear. Spikelets solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 3-4 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 8-14 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pubescent.
    Fertile
    Spikelets comprising 3-4 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 8-14 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pubescent.
    Glume
    Glumes collateral; persistent; similar; reaching apex of florets. Lower glume lanceolate; 6-8.5 mm long; 0.8-0.9 length of upper glume; coriaceous; much thinner on margins; without keels; 3-5 -veined. Lower glume lateral veins prominent. Lower glume surface scabrous; rough on veins. Lower glume apex attenuate; awned; 1 -awned. Lower glume awn 1-3 mm long. Upper glume lanceolate; 7.5-10 mm long; 1 length of adjacent fertile lemma; coriaceous; with hyaline margins; without keels; 3-5 -veined. Upper glume lateral veins prominent. Upper glume surface scabrous; rough on veins. Upper glume apex attenuate; awned; 1 -awned. Upper glume awn 1-3 mm long.
    Florets
    Fertile lemma lanceolate, or oblong; 7-9.5 mm long; coriaceous. Lemma surface pubescent. Lemma apex acute; awned; 1 -awned. Principal lemma awn straight, or curved; 10-30 mm long overall. Palea lanceolate; 1 length of lemma. Palea keels ciliolate. Palea surface puberulous; hairy on back. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; membranous. Anthers 3; 2.5 mm long; yellow. Stigmas 2. Ovary pubescent on apex.
    Fruits
    Caryopsis with adherent pericarp.
