Abstract: Studying on the history of classification of Yulania denudata and the specimens which were gathered by author for many years. The results indicate that Y. denudata is a community which has both wild and cultivated plant, and which has morphological diversity. Based on these results, authors put forward the new classification system of Y. denudata, that is species-subspecies-varieties, which concludes 2 subspecies (1 new combination subspecies), 6 varieties (1 new variety and 3 new translation varieties). The development of deformation theory, selection and utilization of new cultivars of Y. denudata can be based on these results.
