Culm internodes usually 30–110 cm; wall often less than 8 mm thick, but sometimes to 2 cm thick. Branchlets of lower branches never specialized into thorns. Branches usually absent on lower culm, usually subequal. Culm sheaths thickly papery; auricles small or absent, often narrowly oblong; blade deciduous, narrow, only ca. 1/3 width of sheath apex. Pseudospikelets purple-brown or bronze-colored.
About 14 species: S China, N Vietnam; 14 species (12 endemic) in China.
