Resumen
- A new species of Viola L. from Guangdong Province, China, V. guangzhouensis A. Q. Dong, J. S. Zhou & F. W. Xing, is described and illustrated here. The new taxon represents a fifth species in Viola sect. Diffusae (W. Becker) Ching J. Wang, and a taxonomic key to distinguish these taxa in China is included. Viola guangzhouensis is distinct from the sympatric V. diffusa Gingins by having obviously aerial stems, brownish purple stolons, and a bearded anterior petal. The new species is a narrow endemic, collected only from Dalingshan in Guangzhou, Guangdong Province, and is assessed as Critically Endangered (CR).
