Abstract: Two species of Begonia L. (Begoniaceae)ꎬ viz. Begonia demissa Craib and Begonia subperfoliata Parish
ex Kurz are reported as new records in Chinaꎬ and the two species assigned to Begonia sect. Parvibegonia A. DC.
and Begonia sect. Diploclinium (Wight) A. DC. respectively. The type locality of Begonia demissa is in Thailand
and of Begonia subperfoliata in Myanmar. The distribution of Begonia demissa is now extended to Mengyuanꎬ Mengla
County of Xishuangbanna Dai Autonomous Prefecture and that of Begonia subperfoliata to Liushun Communityꎬ Pu’er
Cityꎬ both in Yunnan provinceꎬ China.

with specimens in herbaria ( BMꎬ Eꎬ Kꎬ PE and

the flora of China and adjacent regions ( Smith et
