Culm-internodes terete; hollow; 5–18 cm long; dark green; mottled (purple); smooth. Culm-nodes with distinct supra-nodal ridge. Lateral branches dendroid. Branch complement several; with subequal branches; thinner than stem. Culm-sheaths tardily deciduous; coriaceous; smooth; glabrous; hairy on margins; asymmetrical at apex; without auricles; glabrous on shoulders. Culm-sheath ligule 1 mm high; ciliolate. Culm-sheath blade lanceolate; erect, or reflexed; glabrous on surface and with ciliate margins. Leaves 3–7 per branch. Leaf-sheaths glabrous on surface. Leaf-sheath oral hairs lacking. Ligule an eciliate membrane; 1 mm long; purple; truncate. Collar without external ligule. Leaf-blade base cuneate; with a brief petiole-like connection to sheath. Leaf-blades lanceolate; 7–10 cm long; 6–15 mm wide. Leaf-blade venation with 8–10 secondary veins; with distinct cross veins. Leaf-blade surface glabrous. Leaf-blade margins scabrous.

INFLORESCENCE Synflorescence compound; with principal spatheoles embracing a compact fascicle of racemes, each subtended by a subsidiary bract. Inflorescence composed of racemes; bracteate at pedicel base; subtended by a spatheole; embraced at base by subtending leaf.

Racemes 1; single; unilateral.
