Leaf-blades flat, or involute; 12-20 cm long; 2-3 mm wide; glaucous. Leaf-blade surface scabrous; rough adaxially.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; bilateral; 6-13 cm long. Rhachis flattened; scabrous on margins. Spikelet packing broadside to rhachis; lax. Rhachis internodes oblong; 10-12 mm long. Spikelets solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 10-18 mm long; breaking up at maturity; disarticulating below each fertile floret.
    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.

    Glumes persistent; similar; shorter than spikelet. Lower glume oblong; 6-8 mm long; 0.75-0.9 length of upper glume; coriaceous; without keels; 5-7 -veined. Lower glume lateral veins ribbed. Lower glume apex truncate, or obtuse. Upper glume oblong; 8-9 mm long; 0.9 length of adjacent fertile lemma; coriaceous; without keels; 5-7 -veined. Upper glume lateral veins ribbed. Upper glume surface smooth. Upper glume apex truncate, or obtuse.
    Florets
    Fertile lemma lanceolate, or oblong; 8.5-10 mm long; coriaceous; keeled; keeled above; 5 -veined. Lemma surface smooth. Lemma apex apiculate; muticous. Palea 1 length of lemma. Apical sterile florets resembling fertile though underdeveloped.
