Monimopetalum chinense Rehd. belonging to a monotypic and endemic genus and is the second class conservative tree of rare and endangered species in China as well as the geog-raphical element of East China flora. This paper deals with the ecological characters of natural habitat, geographical distribution, spatial pattern, community composition, quantitative features, population size and reproductive ecology of the species. The results of investigation indicate that the distribution of M.Chinense is very narrow, natural habitat is fragmentary and its population Shows colonial distribution pattern. The community composition and structure are complex. The trees of Cunninghamia lanceolata, Pinus massoniana, Alniphyllum fortunei etc. are dorminant in the community.
