Abstract

Based on field surveys and a review of literature and herbarium specimens, three new Begonia in section Platycentrum from South China are confirmed and reported with morphological descriptions and illustrations, namely Begonia liangguangensis D.K.Tian & J.Y.Zhou, B. shaoqingii D.K.Tian & J.Y.Zhou, and B. qinzhouensis D.K.Tian & J.Y.Zhou. These three new species are morphologically compared with their allied species. Their conservation statuses are provisionally assessed as Endangered, Endangered, and Critically Endangered, respectively, according to Guidelines for Using IUCN Red List Categories and Criteria.
