Abstract

Violashiweii Xiao C. Li & Z. W. Wang (Violaceae), a new species from Guizhou, China, is described, based on morphological and molecular evidence. The new species is morphologically most similar to V.kwangtungensis Melchior in its glabrous lateral petals and stoloniferous habit, but can be distinguished by its obtuse teeth along the leaf margin, its abaxially greyish-green leaf blade and its broader and entire sepals with a distinct basal appendage.

Keywords: Morphology; phylogeny; sect. Plagiostigma; subg. Viola.
