    [GB]
    Habit
    Perennial; caespitose; clumped moderately, or densely. Rhizomes short; pachymorph. Culms erect; 200-300 cm long; 30-50 mm diam.; woody. Culm-internodes terete; thick-walled; smooth, or scaberulous; distally glabrous, or pubescent. Lateral branches dendroid. Bud complement 1. Branch complement one to two; subtended by a bare patch above the node; thinner than stem. Culm-sheaths 3-5 cm long. Culm-sheath blade lanceolate; deciduous; reflexed; 3-4 cm long; 10-13 mm wide. Leaves 11-17 per branch. Leaf-sheaths glabrous on surface, or puberulous. Leaf-sheath oral hairs setose; spreading; 4-9 mm long; dark. Ligule an eciliate membrane; 0.5-1 mm long; brown. Collar with external ligule. Leaf-blade base truncate, or broadly rounded; symmetrical, or asymmetrical; with a brief petiole-like connection to sheath; petiole 0.15-0.5 cm long. Leaf-blades reflexed; lanceolate; 11-16 cm long; 10-16 mm wide. Leaf-blade surface scaberulous; rough adaxially; puberulous; hairy abaxially. Leaf-blade apex acuminate.
    Inflorescences
    Inflorescence composed of racemes. Peduncle 4-10 cm long. Racemes 1; single; bilateral; 15-30 cm long; bearing 12-20 fertile spikelets on each. Rhachis puberulous on surface; scabrous on margins. Spikelet packing broadside to rhachis; distant. Spikelets solitary. Fertile spikelets sessile, or sessile and pedicelled. Pedicels 1-2 mm long.
    Spikelets
    Spikelets comprising 9-15 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 40-80(-100) mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 2-3 mm long.
    Fertile
    Spikelets comprising 9-15 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 40-80(-100) mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 2-3 mm long.
    Glume
    Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma, or similar to fertile lemma in texture. Lower glume lanceolate; 4-6 mm long; 0.66-0.75 length of upper glume; membranous; 1-keeled; keeled above; 3-5 -veined. Lower glume apex acute. Upper glume lanceolate; 6-8 mm long; 0.66 length of adjacent fertile lemma; membranous; 1-keeled; keeled above; 7-9 -veined. Upper glume apex acute.
    Florets
    Fertile lemma lanceolate; 9-11.5 mm long; 1.3-2 mm wide; membranous, or coriaceous; keeled; (9-)11-13(-15) -veined. Lemma apex acute. Palea 8-11 mm long; 1-1.1 length of lemma; 4 -veined. Apical sterile florets resembling fertile though underdeveloped.
