51FE44B84B5B5DCE8D99DEED3EC11BA6.taxon	diagnosis	Diagnosis. The new species is morphologically similar to G. multifolius, but differs by having densely white pubescence (vs. glabrous) on the culm leaf sheaths, culm leaf blades erect (vs. reflexed); apical branch sheaths much longer (vs. slightly longer or equilong) than the internodes; foliage leaf blades mesophyll (vs. notophyll).	en	Wang, Cheng-Kun, Guo, Rong, Guo, Chun-Ce, Yang, Guang-Yao, Zhang, Wen-Gen (2023): Gelidocalamus zixingensis (Poaceae, Bambusoideae, Arundinarieae), a new species from southern China revealed by morphological and molecular evidence.
