Abstract: This paper first describes the distribution of the Manglietia and M. fordiana in China that is the dominant or the main associate or companion species in the forest vegetation in certain subtropical regions of the country, and then, it makes an analysis of the rare Forests that takes the Manglietia fordiana as its community-forming species. Manglietia fordiana is distributed in Jiangxi in the Jinggang Mountain and the Guanshan Nature Reserve. In order to provide original data for the protection of species like the Manglietia fordiana, the authors propose that studies should be made on vegetation types that are formed mainly of rare plants.
