Abstract

Begonia is a mega-genus with about 2500 species by most estimates, with China having over 210 accepted species. After field surveys, literature review and examination of herbarium specimens, some new taxa, new records, synonyms and the hybrid-origin of some taxa have been confirmed. Here, we report that Begonia dioica Buch.-Ham. ex D.Don and B. flagellaris Hara, both from Xizang (Tibet) are new to China; Begonia lipingensis Hance, B. muliensis T.T.Yu and B. sizemoreae Kiew are synonyms of B. circumlobata Hance, B. taliensis Gagnepain and B. longiciliata C.Y.Wu, respectively; and Begonia × lancangensis S.H.Huang and B. × malipoensis S.H.Huang & Y.M.Shui are natural hybrids.
