    [GB]
    Habit
    Perennial. Rhizomes elongated. Butt sheaths persistent and investing base of culm; with fibrous dead sheaths. Culms erect, or geniculately ascending; 40-75 cm long; 2-3 mm diam.; 2-3 -noded. Leaves mostly basal. Leaf-sheaths puberulous. Ligule an eciliate membrane; 1-2 mm long; truncate. Leaf-blades involute; 6-18 cm long; 2-4 mm wide; stiff. Leaf-blade surface puberulous; sparsely hairy; hairy on both sides.
    Inflorescences
    Inflorescence composed of racemes. Peduncle pubescent above. Racemes 1; single; erect; bilateral; 8-18 cm long; 6-8 mm wide. Rhachis flattened; pubescent on surface. Spikelet packing broadside to rhachis. Rhachis internodes 5-50 mm long. Spikelets solitary, or in pairs. Fertile spikelets pedicelled; 1-2 in the cluster. Pedicels 1-14 mm long; pubescent.
    Spikelets
    Spikelets comprising 4-8 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 11-18 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 0.5-2 mm long; pubescent.
    Fertile
    Spikelets comprising 4-8 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 11-18 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 0.5-2 mm long; pubescent.
    Glume
    Glumes persistent; similar; subequal in width; shorter than spikelet. Lower glume linear, or lanceolate; 5-6.5 mm long; 1 length of upper glume; coriaceous; much thinner on margins; 1-keeled; 1-3 -veined. Lower glume lateral veins absent, or obscure. Lower glume surface smooth to scabrous. Lower glume apex attenuate; awned; 1 -awned. Lower glume awn 2-4 mm long. Upper glume linear, or lanceolate; 6-7.5 mm long; 0.75-0.9 length of adjacent fertile lemma; coriaceous; with membranous margins; 1-keeled; 1-3 -veined. Upper glume lateral veins absent, or obscure. Upper glume surface smooth, or scabrous. Upper glume apex attenuate; awned; 1 -awned. Upper glume awn 2-4 mm long.
    Florets
    Fertile lemma lanceolate; 7-10 mm long; chartaceous; shiny; keeled; 5 -veined. Lemma lateral veins obscure. Lemma surface smooth, or scabrous. Lemma margins pubescent. Lemma apex acuminate; awned; 1 -awned. Principal lemma awn 1-3 mm long overall. Palea 0.9 length of lemma; 2 -veined; 2-keeled. Palea keels scaberulous. Palea surface glabrous. Palea apex dentate; 2 -fid. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Anthers 3; 9 mm long; yellow. Ovary pubescent on apex.
    Fruits
    Caryopsis with adherent pericarp; 4-9 mm long; hairy at apex.
