Shrubby bamboo. Rhizome long necked, pachymorph. Culms diffuse, basally erect with pendulous or clambering tips; internodes terete, glabrous; wall very thin; nodal ridge and sheath scar flat. Branches many, clustered at each node, subequal. Culm sheath deciduous, shorter or longer than internode, basally initially with dense, deep brown, bristly hairs, apex truncate or shallowly arched-concave; auricles very small; ligule short; blade deciduous, usually erect. Leaf blade large, transverse veins scarcely visible abaxially. Inflorescence fully bracteate, iterauctant, subtended by scaly bracts. Pseudospikelets solitary or several clustered in axils of bracts, small, with 1 fertile floret. Rachilla extending beyond palea of fertile floret, with 1 sterile floret. Glume 1, long mucronate to awned; lemma similar to glume. Palea thin, 2-keeled. Lodicules 3–5, persistent. Stamens 6; filaments free; anthers apiculate at apex.
