    [GB]
    Habit
    Perennial. Culms erect; 70-110 cm long; 2-3 mm diam.; 3-4 -noded. Leaves mostly basal. Leaf-sheaths antrorsely scabrous. Ligule an eciliate membrane; 0.8 mm long. Leaf-blades flat, or convolute; 10-25 cm long; 3-5 mm wide; stiff. Leaf-blade surface scabrous; rough adaxially; glabrous, or pubescent; densely hairy; hairy adaxially.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; erect; bilateral; 8-15 cm long; 10-13 mm wide. Rhachis flattened; puberulous on surface. Spikelet packing broadside to rhachis. Rhachis internodes 6-20 mm long. Spikelets in pairs. Fertile spikelets sessile; 2 in the cluster.
    Spikelets
    Spikelets comprising 5-9 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 18-25 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 0.5-1.5 mm long; pubescent.
    Fertile
    Spikelets comprising 5-9 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 18-25 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 0.5-1.5 mm long; pubescent.
    Glume
    Glumes persistent; similar; subequal in width; shorter than spikelet. Lower glume lanceolate; 11-14 mm long; 1 length of upper glume; coriaceous; much thinner on margins; 1-keeled; 3-5(-7) -veined. Lower glume margins ciliate. Lower glume apex setaceously attenuate. Upper glume lanceolate; 11-16 mm long; 1 length of adjacent fertile lemma; coriaceous; with membranous margins; 1-keeled; 3-5(-7) -veined. Upper glume margins ciliolate. Upper glume apex setaceously attenuate.
    Florets
    Fertile lemma lanceolate; 10-12 mm long; chartaceous; keeled; 5-7 -veined. Lemma surface pilose. Lemma apex acuminate; awned; 1 -awned. Principal lemma awn 1-2 mm long overall. Palea 1 length of lemma; 2 -veined; 2-keeled. Palea keels ciliate. Palea apex emarginate. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Anthers 3; 5 mm long; yellow.
    Fruits
    Caryopsis with adherent pericarp.
