Leaf-blades 10-15 cm long; 2-3 mm wide; glaucous. Leaf-blade surface ribbed; scabrous; rough abaxially; pilose; sparsely hairy; hairy adaxially. Leaf-blade margins scabrous. Leaf-blade apex acuminate.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; erect; bilateral; 14-16 cm long. Rhachis flattened; smooth on margins, or scaberulous on margins. Spikelet packing broadside to rhachis; lax. Spikelets solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 4-6 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 12-15 mm long; falling entire. Spikelet callus base truncate. Rhachilla internodes sparsely hairy.
    Fertile
    Spikelets comprising 4-6 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 12-15 mm long; falling entire. Spikelet callus base truncate. Rhachilla internodes sparsely hairy.
    Glume
    Glumes similar; shorter than spikelet. Lower glume lanceolate, or oblong; 6-7 mm long; 0.9 length of upper glume; coriaceous; 1-keeled; 4-6 -veined. Lower glume margins ciliolate. Lower glume apex obtuse. Upper glume lanceolate, or oblong; 7-8 mm long; 0.75 length of adjacent fertile lemma; coriaceous; 1-keeled; 4-6 -veined. Upper glume margins smooth, or scaberulous; ciliolate. Upper glume apex obtuse.
    Florets
    Fertile lemma oblong; 8.5-9.5 mm long; coriaceous; keeled; lightly keeled; keeled above; 5 -veined. Lemma margins ciliolate. Lemma apex truncate, or obtuse; mucronate. Principal lemma awn 0.4-0.8 mm long overall. Palea 1 length of lemma; 2 -veined. Palea keels ciliolate. Palea surface puberulous; hairy on back; hairy above. Palea apex emarginate. Apical sterile florets resembling fertile though underdeveloped.
