Abstract: Study on the endemic phenomenon of species and variants under species is provided with a significance of theory and practice to recognize the flora and biodiversity in the mountainous region. The ancient history of biology and geology and the combination of complex and various environments is a common back ground of forming the local endemic plants in Emei Mountain. There are 67 species or variants as the local endemic plants which occupy 218 % of the seed plants there. The major speices belong to warm flora when a few come from tropical flora. And the species rate in the Chinese endemic genera gets quite high. In the same time , the differentiation of these endemic species is very intensive and no less species show the relic2defferential complex features. These endemic plants distribute mainly at the lower2middle position , elevation 1000~1700 m(~ 2000 m) , of the mountainous and the vertical ranges about 7116 % of them do not exceed 400 m. Most of them , especially almost all of the herbaceous species are shade of tolerant2shade. The formation and evolution of these endemic plants is relation to the history and environment in some degree and necessarily to the capabilities in their competition , propagation and dissemination.
