Culms 1.5–3.5 m, 0.9–1.5 cm in diam.; internodes initially yellow or purple, white tomentose, hairs denser and forming a brown ring below nodes; wall ca. 0.4 mm thick; nodes weakly elevated. Culm sheaths purple-green, shorter than internode, leathery, white tomentose and dark brown hairy, base corky; auricles ca. 5 mm, brown; oral setae radiate, flexuose, about as long as auricle; ligule truncate to arcuate, 0.5–2 mm, densely puberulent, margin sparsely or not ciliate; blade broad, amplexicaul, base truncately rounded to cordate, about as wide as apex of culm, apex acuminate. Leaves 2–7 per ultimate branch; sheath striate, white tomentose; auricles and oral setae absent; ligule 1–2.5 mm, pubescent, long ciliate; blade broadly lanceolate, 35–56 × 4–10.5 cm, abaxially minutely appressed white pubescent, adaxially glabrous, secondary veins 8–15 pairs, tessellations rectangular or square, base cuneate, apex acuminate. Inflorescence unknown. New shoots Apr–May.
