Viola fuscopurpurea (Violaceae), a new species from Chongqing, China

Viola fuscopurpurea (Violaceae), a new species from Karst landform of Chongqing in China, is described and illustrated. The new species is most similar to V. fukienensis, but can be distinguished by nearly glabrous, shiny, adaxially purple blades (vs pubescent, adaxially green blades), brown seeds with conspicuous tubercles (versus yellow seeds with smooth surface), and hook-like nectaries (versus triangular nectaries), as well as by general habit. Our phylogenetic analysis, based on ITS sequences, confirms that the new species belongs to V. subsect. Rostratae, and is most closely related to V. fukienensis in the phylogeny.
