Culms solitary or loosely tufted, erect or geniculate and rooting at lower nodes, 45–110 cm tall, leafy. Leaf sheaths smooth or scabrid; leaf blades linear-lanceolate, 8–25 cm × 5–15 mm, scabrid, apex acuminate; ligule 0.5–4 mm, truncate or rounded. Panicle open, ovate to pyramidal in outline, 10–25 cm; branches in distant whorls, slender, scabrid, bare in lower part, longest up to 13 cm; pedicels of lateral spikelets variable in length. Spikelets 2.5–5 mm, grayish green; glumes lanceolate, lower glume 0.5–2.5 mm, 1-veined, upper glume 2–3.5 mm, 1–3-veined, keel scabrid, apex acute; callus hairs 0.1–0.8 mm; lemma apex acute to acuminate, sometimes scarious and incurved, rarely mucronate; palea keels prominent, scabrid becoming ciliolate toward apex; rachilla 0.2–1.5 mm, glabrous. Anthers 0.7–1.5 mm. Fl. Jul.
Moist shady often rocky places; 1300–2000 m. Fujian, Guangxi, Guizhou, Hubei, Sichuan, Taiwan, Yunnan [Bhutan, India (Darjeeling, Sikkim), Indonesia (Sumatra), Japan, Malaysia (Sabah), N Myanmar, N Vietnam].
Populations of this grass from different parts of its geographic range have sometimes been separated at specific or varietal rank. However, variation is still little understood, so a broad species concept is followed here.
