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 found 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.
