Culm-internodes distally glabrous. Culm-nodes pubescent. Leaf-sheaths subequal to internodes, or longer than adjacent culm internode; hirsute. Ligule an eciliate membrane; 0.5 mm long; truncate. Leaf-blades flat, or involute; 15-20 cm long; 3-4 mm wide. Leaf-blade surface scabrous; rough abaxially; hirsute; hairy adaxially.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; straight, or arcuate; bilateral; 9.2-10.5 cm long. Rhachis flattened; glabrous on surface; ciliate on margins. Spikelet packing broadside to rhachis. Spikelets solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 4-9 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 13-16 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pubescent. Floret callus pubescent. Floret callus hairs 0.6-0.8 mm long.

Floret callus hairs 0.6-0.8 mm long.
    Glume
    Glumes persistent; similar. Lower glume lanceolate; 5-6.5 mm long; coriaceous; much thinner on margins; without keels; 3-4 -veined. Lower glume surface hirsute. Lower glume apex acuminate; mucronate. Upper glume lanceolate; 6.5-7.5 mm long; coriaceous; with membranous margins; without keels; 4-5 -veined. Upper glume surface hirsute. Upper glume apex acuminate; mucronate.
    Florets
    Fertile lemma oblong; 7.5-8 mm long; coriaceous; 5 -veined. Lemma surface scabrous; rough above; pubescent; hairy below. Lemma apex acuminate; awned; 1 -awned. Principal lemma awn 10-20 mm long overall. Palea 0.9-1 length of lemma; 2 -veined. Palea keels ciliate; adorned above; with 0.5-0.75 of their length adorned. Palea surface pubescent; hairy on back. Palea apex obtuse. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
