[英文摘要]Xishuangbanna Dai Autonomous Prefecture is located in the south of Yunnan Province, China. It has complex geology, biogeography, vegetation types, and floristic composition characteristic of the tropical Asia flora. Based on field investigations and data analysis, we report two newly recorded species distributed in China: (1) Thepparatia scandens (Roxb. Ex G.Don) Phuph. (Malvaceae), originally mainly distributed in India and Thailand, it is also a new genus record to China. Descriptions and photographs are provided and a new lectotype is here designated. (2) Aspidistra mushaensis Hayata, native to Taiwan, is a new species record in Yunnan. The discovery of these new records contributes to the diversity of the Yunnan floristic region and provides an example of the close affinity between the flora of southern Yunnan and the tropical Asian flora (Indo-Malesia). It also provides examples for the formation and evolution of East Asian flora.
