摘要：
Begonia chongzuoensis Yan Liu, S. M. Ku & C.-I Peng (sect. Coelocentrum), a new species from Guangxi Zhuangzu Autonomous Region, China, is here described and illustrated. A somatic chromosome number of 2n = 30 was determined. Begonia chongzuoensis somewhat resembles B. obliquiplia S. H. Huang & Y. M. Shui, from which it differs by the moderately to sparsely setulose leaf surface; glabrous inflorescences, flowers and fruits; and crescent-shaped abaxial wing of the fruit. The new species is known only from a limestone hill in western Guangxi.
