Abstract: YunnanGuizhouGuangxi and some of their neighbouring areas formed a distributional and endemic center of Gesneriaceae during its evolutionary process in China.Among 38 genera and 166 species being bound in Guangxi,there are 5 genera and 81 species belonging to endemism.By comparison of the genera with those of the neighbouring areas,the generic similarity coefficient of Guangxi to Guizhou and Yunnan reaches to 7576% and 7142% respectively,but to the other neighbouring provinces only reaches to a lower rangs from 3548% to 649%.As the taxa require a strict bed rock to live,they distribute in Guangxi unevenly.The individuals of each species are always fewer and present larger interpopulation variation.

Key words: Guangxi
