    [GB]
    Habit
    Perennial; caespitose. Culms 25-50 cm long. Leaf-sheaths mostly shorter than adjacent culm internode. Leaf-sheath auricles falcate; 1 mm long. Ligule an eciliate membrane; 0.5 mm long; truncate. Leaf-blades flat, or conduplicate, or involute; 2.5-7 cm long; 2-5 mm wide. Leaf-blade surface glabrous.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; drooping; flexuous; bilateral; 4-13 cm long. Rhachis flattened; glabrous on surface. Spikelet packing broadside to rhachis; lax. Rhachis internodes linear; 8-17 mm long. Spikelets in pairs. Fertile spikelets sessile, or sessile and pedicelled. Pedicels 1 mm long; pubescent.
    Spikelets
    Spikelets comprising 3-4 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 8-15 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 2-3 mm long; pubescent.
    Fertile
    Spikelets comprising 3-4 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 8-15 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 2-3 mm long; pubescent.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 4 mm long; 0.75 length of upper glume; coriaceous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume surface scabrous; rough on veins; glabrous. Lower glume apex acuminate. Upper glume lanceolate; 5 mm long; 0.5-0.75 length of adjacent fertile lemma; coriaceous; without keels; 3 -veined. Upper glume surface scabrous; rough on veins; glabrous. Upper glume apex acuminate.
    Florets
    Fertile lemma lanceolate, or oblong; 7-9 mm long; coriaceous; 5 -veined. Lemma surface scaberulous. Lemma apex acute; awned; 1 -awned. Principal lemma awn ascending, or spreading; 5-15 mm long overall. Palea 1 length of lemma. Palea keels scaberulous. Palea surface scaberulous (above). Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Anthers 3; 1.5 mm long; yellow.
