Leaf-sheaths smooth; glabrous on surface. Leaf-sheath auricles absent. Ligule an eciliate membrane; 0.5 mm long. Leaf-blades 4-25 cm long; 3-6 mm wide; stiff; glaucous. Leaf-blade surface scabrous; rough adaxially. Leaf-blade margins scabrous. Leaf-blade apex attenuate; pungent.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; bilateral; 12-16 cm long; bearing 10-18 fertile spikelets on each. Rhachis ciliate on margins. Spikelet packing broadside to rhachis. Rhachis internodes linear; 10-20 mm long. Rhachis internode tip flat. Spikelets solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 5-6 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 5-6 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 2.5-3 mm long; pilose.
    Fertile
    Spikelets comprising 5-6 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 5-6 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 2.5-3 mm long; pilose.
    Glume
    Glumes collateral; persistent; similar; shorter than spikelet. Lower glume linear; 5-7 mm long; 0.66 length of upper glume; coriaceous; without keels; 1(-3) -veined. Lower glume lateral veins absent, or obscure. Lower glume apex acuminate; muticous. Upper glume lanceolate; 8-10 mm long; coriaceous; without keels; 3 -veined. Upper glume apex acuminate; muticous.
    Florets
    Fertile lemma lanceolate; 12-14 mm long; coriaceous; 5-7 -veined. Lemma surface pubescent. Lemma margins ciliolate. Lemma apex acuminate to setaceously attenuate. Palea keels ciliolate. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
