    [GB]
    Habit
    Perennial; culms solitary. Basal innovations intravaginal. Culms erect; 75-100 cm long; 2.5-3.5 mm diam. Culm-internodes 10-26.5 cm long; distally glabrous, or pubescent; with reflexed hairs. Culm-nodes constricted; pubescent. Leaf-sheaths loose; 18-25 cm long; mostly shorter than adjacent culm internode; striately veined; glabrous on surface. Ligule an eciliate membrane; 1 mm long; erose. Leaf-blades 12.5-23 cm long; 4.5-8 mm wide. Leaf-blade surface scaberulous; rough adaxially, or on both sides.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; erect, or drooping; bilateral; 11-14 cm long; 5-8 mm wide. Rhachis flattened; puberulous on surface; ciliate on margins. Spikelet packing broadside to rhachis. Rhachis internodes linear; 3-14 mm long. Spikelets in pairs, or in threes. Fertile spikelets sessile; 2-3 in the cluster.
    Spikelets
    Spikelets comprising 3-4 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 12-15 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 3 mm long; pubescent. Floret callus pubescent.
    Fertile
    Spikelets comprising 3-4 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 12-15 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 3 mm long; pubescent. Floret callus pubescent.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate, or oblong; 9-10 mm long; 1 length of upper glume; coriaceous; without keels; 3-5 -veined. Lower glume primary vein scabrous. Lower glume surface scabrous. Lower glume apex acuminate. Upper glume lanceolate, or oblong; 9-10 mm long; 1 length of adjacent fertile lemma; coriaceous; without keels; 3-5 -veined. Upper glume primary vein scabrous. Upper glume surface scabrous. Upper glume apex acuminate.
    Florets
    Fertile lemma lanceolate; 9-10 mm long; coriaceous; 5 -veined. Lemma surface puberulous. Lemma apex acute; awned; 1 -awned. Principal lemma awn 20-30 mm long overall. Palea keels ciliolate; adorned above. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Anthers 3; 2-2.5 mm long; brown. Stigmas 2. Ovary pubescent on apex.
    Fruits
    Caryopsis with adherent pericarp.
