    Habit
    Perennial; caespitose. Rhizomes absent, or short. Culms 50-200 cm long; 5-8 -noded. Leaf-sheaths glabrous on surface, or pubescent. Leaf-sheath auricles falcate. Ligule an eciliate membrane; 1-3 mm long; truncate. Leaf-blades 3-12 mm wide. Leaf-blade surface scabrous; rough adaxially; glabrous, or pubescent; hairy adaxially, or on both sides.
    Inflorescences
    Inflorescence composed of racemes. Peduncle smooth, or retrorsely scabrous above. Racemes 1; single; bilateral; 10-15 cm long. Rhachis scabrous on margins. Spikelet packing broadside to rhachis. Rhachis internodes linear. Rhachis internode tip flat. Spikelets in pairs, or in threes. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 10-18 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes scaberulous.
    Fertile
    Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 10-18 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes scaberulous.
    Glume
    Glumes persistent; similar; with lower wider than upper; shorter than spikelet. Lower glume lanceolate; 6.5-9 mm long; 1 length of upper glume; coriaceous; without keels; 4-5 -veined. Lower glume lateral veins ribbed. Lower glume surface scabrous; rough on veins. Lower glume apex acuminate; muticous, or awned; 1 -awned. Lower glume awn 1-5 mm long. Upper glume lanceolate; 6.5-9 mm long; 0.75-1 length of adjacent fertile lemma; coriaceous; without keels; 3 -veined. Upper glume lateral veins ribbed. Upper glume surface scabrous; rough on veins. Upper glume apex acuminate; muticous, or awned; 1 -awned. Upper glume awn 1-5 mm long.
    Florets
    Fertile lemma lanceolate; 6.5-12 mm long; coriaceous; 5-7 -veined. Lemma surface scabrous; rough above. Lemma apex dentate; 2 -fid; acute; awned; 1 -awned. Principal lemma awn from a sinus; 11-15 mm long overall. Palea 1 length of lemma. Palea keels ciliate. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
