Abstract
Begonia shenzhenensis D.K.Tian & Xiao-Yun Wang sp. nov., a new species in Begonia sect. Platycentrum of Begoniaceae from Shenzhen of Guangdong province, China, is described.

Based on only one small population ever found so far, its conservation status is assigned to Critical Endangered according to the IUCN Red List Categories and Criteria.
