Plant tufted or shortly rhizomatous. Culms (30–)80–200 (–400) cm tall, 3–10 mm in diam., solid, unbranched, nodes glabrous or puberulous. Leaves basal and cauline; leaf sheaths glabrous or pilose; leaf blades linear, flat, 18–75 × 0.3–2(–4) cm, glabrous, glaucous or pilose, midrib prominent, margins scabrid or smooth, base tapering or broad and rounded, apex acuminate; ligule 0.5–4 mm, ciliolate. Panicle (10–)20–36 cm; axis 6–16 cm, subglabrous to pilose or puberulous. Racemes (4–)10–40(–100), (8–)10–30 cm; rachis internodes glabrous, scaberulous or smooth, nodes glabrous; lower pedicel 0.5–1.5 mm, upper pedicel 1.5–4 mm. Spikelets 4–6.5 mm, pilose or glabrous, awned; callus hairs 5–8 mm, exceeding the spikelet; glumes subequal, membranous, 4–6.5 mm, 5-veined, back glabrous or pilose, puberulous at apex and along upper margins, apex acuminate; lower lemma lanceolate, hyaline, 3.5–4 mm, veinless, apex and margins puberulous, otherwise glabrous; upper lemma similar to lower, 2.5–3.5 mm; awn geniculate, 4–12 mm; upper palea a 1–2 mm scale. Anthers 3, ca. 2.5 mm. Caryopsis ellipsoid, ca. 2 mm.
Robust, 2–3 m, in large tufts; lvs elongate, to 1 m, ca 1 cm wide, scabrous-margined; racemes simple, rather closely approximate, forming a fan-shaped panicle; glumes narrow, 3–4 mm, subtended and equaled or shortly exceeded by a ring of long silky hairs; lemmas 2–3 mm, the fertile one with an awn 6 mm; 2n=35–57. Native of China, cult. for ornament and occasionally escaped. Autumn.
A grass that keeps growing from year to year. It can be in tufts or have short rhizomes. It grows 80-200 m tall. The stems are 3-10 mm across. The leaf blades are flat and 18-75 cm long by 1-2 cm wide.
