Abstract

China has an exceptional diversity in Begonia, holding the second largest number of described species in this genus at the national level. Many new taxa need to be explored and described. This paper reports two new species, Begonia ruchengensis (B. sect. Reichenheimia) and B. auritalata (B. sect. Platycentrum), from Hunan province and Guizhou province, respectively. Besides the detailed morphology description, color illustrations, and line drawings, the diagnoses of these two species distinguished from their allied taxa are provided. Their conservation statuses are evaluated according to The Guidelines for Using the IUCN Red List Categories.
