    [GB]
    Habit
    Perennial; caespitose. Rhizomes elongated. Culms 20-40 cm long. Culm-internodes smooth. Lateral branches sparse. Leaf-sheaths glabrous on surface. Leaf-sheath auricles falcate. Ligule an eciliate membrane; 0.5-1 mm long. Leaf-blades 3-7 mm wide; coriaceous; stiff; glaucous. Leaf-blade surface ungrooved; scabrous; rough adaxially. Leaf-blade margins scabrous.
    Inflorescences
    Inflorescence composed of racemes. Peduncle antrorsely scabrous above; glabrous. Racemes 1; single; linear; bilateral; 6-10 cm long; 15 mm wide. Rhachis ciliate on margins. Spikelet packing broadside to rhachis. Rhachis internodes linear. Spikelets appressed; solitary, or in pairs. Fertile spikelets sessile and pedicelled; 1-2 in the cluster. Pedicels 3-5 mm long.
    Spikelets
    Spikelets comprising 5-10 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 15-20 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus glabrous, or sparsely hairy; obtuse.
    Fertile
    Spikelets comprising 5-10 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 15-20 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus glabrous, or sparsely hairy; obtuse.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume linear; 6-8 mm long; 1 length of upper glume; chartaceous; 1 -veined. Lower glume lateral veins absent. Lower glume inner surface pubescent. Upper glume linear; 6-8 mm long; 0.8-1 length of adjacent fertile lemma; chartaceous; 1 -veined. Upper glume lateral veins absent. Upper glume inner surface pubescent.
    Florets
    Fertile lemma lanceolate, or ovate; 7-8 mm long; coriaceous; without keel; 5-7 -veined. Lemma apex acuminate; muticous, or awned; 1 -awned. Principal lemma awn 0-3 mm long overall. Palea 2 -veined. Palea keels ciliate. Apical sterile florets resembling fertile though underdeveloped.
