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 <i>Indosasa</i>. The new species, named <i>I. fimbriligulata</i>, is morphologically similar to <i>I. glabrata</i> 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.
