Abstract:

 Begonia menglianensis YY. Qian was regarded as a synonym of Begonia augustinei Hemsl. After comparing the type and additional collections made from the type locality, we found that this species is distinct, and mostly similar to Begonia rex Putz. in its fruit morphology. However, it can be easily distinguished by its flat and nearly triquetrous superior edge of the major fruit wing. Together with information on its pollen and seeds observed under Scanning Electronic Microscope, a revised description for Bmenglianensis is provided.
