Rhizome neck 5–11 cm. Culms 4–6 m, 1.5–2.5 cm in diam.; internodes terete, 20–23 cm, longitudinal ribs absent, initially white powdery, glabrous; wall 3–6 mm thick, pith initially spongy; supra-nodal ridges weakly prominent; sheath scar prominent, yellow-brown setose, with persistent remains of sheath base; intranode 2–4 mm. Branches 9–25 per node. Culm sheaths persistent, yellow-brown, spotted purple-brown, narrowly triangular or narrowly rounded, proximally leathery, distally papery, brown to dark brown setulose, longitudinal ribs prominent, margins sometimes brown to dark brown setose; auricles absent; oral setae deciduous, brown; ligule yellow-brown, truncate, ca. 1 mm, glabrous; blade reflexed, linear-lanceolate, glabrous.
