The shoots are edible, and the culms are used for weaving and making paper and farm tools.

Rhizome neck 5–12 cm, 3–6 cm in diam. Culms 4–6(–8 m), 2–4(–6) cm in diam.; internodes blue-gray, terete, 22–28 cm, densely white powdery, distally gray-brown to yellow-brown setose, longitudinal ribs prominent, nearly solid; nodes initially white powdery, supra-nodal ridges weakly prominent; sheath scar very prominent, initially brown tomentose. Branches 3–7 per node, strong; buds yellow, ovoid, waxy, basally white powdery, marginally densely yellow-brown ciliate. Culm sheaths deciduous, slightly longer than internode, leathery to thickly so, rigid, triangularly narrowly rounded, sparsely yellow-brown setose, longitudinal ribs prominent, margins densely brown setose; auricles absent; oral setae few, erect or slightly curved, brown, 3–6 mm; ligule dark purple, level or convex, 2–3 mm, margins gray-brown ciliate; blade reflexed, linear-lanceolate, glabrous, margins serrulate, apex long acuminate. Leaves 3–5 per ultimate branch; sheath glabrous, longitudinal ribs prominent; auricles absent; oral setae sparse, yellow-brown, ca. 2 mm; ligule truncate or arcuate, glabrous, setulose; blade lanceolate, 10–18 × 1.6–2.3 cm, both surfaces glabrous, secondary veins 5- or 6-paired, transverse veins distinct, base cuneate, margins spinescent-serrulate.
