%X <i>Begonia kuofangii</i>, from Leiping Town, Daxin County is a new species endemic to the Guangxi Zhuang Autonomous Region, China. This is the latest addition to <i>Begonia</i> section Coelocentrum. It resembles <i>Begonia subcoriacea</i> C.-I Peng, Yan Liu, S. M. Ku but differs in leaf shape (ovate-oblong vs widely ovate or suborbicular), peduncle and pedicels indumentum (subglabrous vs glandulose-pilose with reddish trichomes), pistillate flower tepals (2(-3) vs 3). Only about 100 mature individuals were found in less than 5 km2 area, hence <i>Begonia kuofangii</i> is provisionally assessed as Critically Endangered (CR).
