    Habit
    Perennial; caespitose; clumped densely. Culms geniculately ascending; 70-120 cm long. Culm-internodes smooth; distally glabrous. Culm-nodes glabrous, or pubescent. Ligule an eciliate membrane. Leaf-blades 8-15 mm wide. Leaf-blade surface scaberulous; rough abaxially; pilose; sparsely hairy; hairy adaxially.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; straight; bilateral; 13-18 cm long. Rhachis flattened; scabrous on margins. Spikelet packing broadside to rhachis; crowded. Rhachis internodes linear. Spikelets solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 10-15 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pilose. Floret callus pilose.
    Fertile

    Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 9-11 mm long; 1 length of upper glume; coriaceous; much thinner on margins; without keels; 5-7 -veined. Lower glume surface scabrous. Lower glume apex acuminate; awned; 1 -awned. Lower glume awn 2-5 mm long. Upper glume lanceolate; 9-11 mm long; 1 length of adjacent fertile lemma; coriaceous; with hyaline margins; without keels; 5-7 -veined. Upper glume surface scabrous.
