Branches many, main mid-culm branch to 2 cm in diam. Culm sheaths deciduous, ca. 1/2 as long as internodes, leathery, with yellow and brown hairs, apex truncate or slightly concave; auricles small; oral setae several; ligule 2–3 mm, fimbriate; blade reflexed or spreading, abaxially glabrous, base ca. 1/3 as wide as sheath apex. Leaf sheaths glabrous; ligule truncate; auricles narrowly ovate; oral setae deflexed; blade lanceolate, 7–18 × 1–2.5 cm. Pseudospikelets 2–4 cm; gemmiferous bracts progressively larger; florets 7–11.
