174POACEAECulms 8–10 m, 4–6 cm in diam.; internodes bright green,not white powdery, becoming yellow-green or green, 30–42 cmin mid-culm, initially sparsely retrorsely white hairy, becomingglabrous; wall 3–7 mm thick; nodal ridge weakly elevated, asprominent as or slightly more prominent than sheath scar. Culmsheaths green or green-purple to purple, with pale yellow oryellow-green stripes, usually with sparse, small, dark spots,distal margins purple, apex broadly truncate or slightly convex;auricles absent to 2, purple, falcate, small to large; oral setaepurple; ligule purple, usually slightly arcuate or truncate,relatively short, broad, with longer purple setae, white ciliolate;blade erect or sometimes spreading in upper sheaths, yellowgreenor purple-green, triangular to linear-triangular, marginsproximally purple, nearly flat to weakly crinkled. Leaves 1 or 2per ultimate branch; auricles small or obsolete; oral setae erect;blade 7.5–16 × 1.3–2.2 cm. Inflorescence not known. Newshoots early May. 2n = 48*.Cultivated. Guizhou, Henan, Jiangsu, Shaanxi, Sichuan, Xizang,Yunnan, Zhejiang [India, Myanmar].The inclusion of this species in the IUCN Red List seems difficultto justify given the broad distribution.The culms are split for weaving mats and various articles.26.
