    Habit
    Perennial; caespitose; clumped loosely. Culms erect; 50-80 cm long. Culm-internodes distally glabrous. Culm-nodes black; glabrous. Lateral branches lacking. Leaf-sheaths glabrous on surface. Leaf-sheath auricles absent, or falcate. Ligule an eciliate membrane; 0.6-1 mm long. Leaf-blades flat, or involute; 9-33 cm long; 1-5 mm wide. Leaf-blade surface glabrous to pilose.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; arcuate; bilateral; 7-20 cm long; bearing 4-10 fertile spikelets on each. Spikelet packing broadside to rhachis. Rhachis internodes linear. Spikelets solitary. Fertile spikelets sessile. Pedicels oblong; 1 mm long; puberulous.
    Spikelets
    Spikelets comprising 4-10 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 20-25 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 2-3 mm long; pubescent. Floret callus evident; 1 mm long; pilose; with elliptic scar.
    Fertile
    Spikelets comprising 4-10 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 20-25 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 2-3 mm long; pubescent. Floret callus evident; 1 mm long; pilose; with elliptic scar.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 5-15 mm long; 0.75-0.85 length of upper glume; coriaceous; without keels; 3-5 -veined. Lower glume apex acute. Upper glume lanceolate; 6-18 mm long; 0.8-1.1 length of adjacent fertile lemma; coriaceous; without keels; 6-7 -veined. Upper glume apex acute.
    Florets
    Fertile lemma lanceolate; 11-16 mm long; coriaceous; without keel; 5-7 -veined. Lemma lateral veins convergent above. Lemma surface puberulous. Lemma apex acute; awned; 1 -awned. Principal lemma awn 32-42 mm long overall. Palea 1 length of lemma. Palea keels scabrous. Palea surface puberulous; hairy on back. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; membranous. Anthers 3; 1.5-2 mm long; retained within floret. Stigmas 2. Ovary pubescent on apex.
    Fruits
    Caryopsis with adherent pericarp; 7.5 mm long.
    Distribution
