Abstract
Begonia_kuofangii, from Leiping Town, Daxin County is a new species endemic to the Guangxi Zhuang Autonomous Region, #China. This is the latest addition to Begonia section Coelocentrum. It resembles Begonia subcoriacea 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 Begonia kuofangii is provisionally assessed as Critically Endangered (CR).
