Indosasa fimbriligulata (Poaceae, Bambusoideae), a new bamboo species from Guangxi, China.

Based on morphological and molecular phylogenetic evidence, we confirmed that some bamboo collections from Guangxi, China, represent a new species of Indosasa. The new species, named I. fimbriligulata, is morphologically similar to I. glabrata but differs by having internodes that are white strigose when young, and hollow without or with a little clastic pith, culm buds triangular, culm leaf sheaths abaxially scattered with tufted brown setae, culm leaf auricles well developed, and culm leaf ligule apex long fimbriate. A detailed description, as well as two color plates of this new species, is also provided.
