Abstract: The question of which plant is Mulan'(木兰) in Magnoliaceae in Chinese history on earth has not been solved in science actually. Through field investigation and relative references analysis, we find thatMulan'is the Redflower Magnolia(Magnolia wufengensis) Groups,including a new species named Magnolia wufengensis L. Y. Ma et L. R. Wang'and a new variety named Magnolia wufengensis var. multitepala L. Y. Ma et L. R. Wang', which were found and named in 2006 by MA L-yi, professor of Beijing Forestry University, and WANG Luo-rong, from Hubei Provincial Forest Tree Seed and Seedling Administration Station. Wudang Mulan(武当木兰)(Magnolia sprengeri Pampan,)is a type of M. wufengensis var. multitepala and can be regard as a type below species. Therefore, the discovery of the Redflower Magnolia can help us to identify Mulan'in the ancient literature. The Redflower Magnolia is one of the most important groups in research, protection and development due to its specific area distribution, variety of types, genetic diversity, wide scope of usage and huge values.
