摘要： Two new tuberous species of Begonia (Begoniaceae), Begonia angustibracteata D.K.Tian & R.C.Hu and B. baishishanensis R.C.Hu & D.K.Tian from Guangxi of China are described with illustrations. Begonia angustibracteata has sparsely hairy green leaves, undivided placenta, and a small bracteole at the top of the pedicel of pistillate flower. Begonia baishishanensis has sparsely hispidulous and unlobed leaves, bilaminate placenta and early flowering in March. The differences of these two new species are compared with their allied species, B. fimbristipula and B. danxiaensis. Their conservation status is assessed according to Guidelines for Using IUCN Red List Categories and Criteria.
