    Abstract

    Begonia floriprolifera is a new species of Begonia sect. Coelocentrum distributed in the karst area of southwestern Guangxi of China and northern Vietnam. Morphologically, it is mostly similar to B. bonii, but differs mainly by its nearly glabrous stipules, shorter inflorescence, bilaterally symmetric and upward curved androecium with fewer stamens, and concave apex of anthers. Due to the narrow distribution area and unfavorably environmental changes of its natural habitat, the new species is assigned to Endangered according to the IUCN Red List Categories and Criteria.
