摘　　要：作者对多年来采集的玉兰植物标本进行了分类、整理和研究。结果表明,玉兰是个野生和栽培兼有、形态多样性的复合型种群,并首次提出玉兰种下新分类系统。该新系统是:种—亚种—变种,其中包括2亚种(1新组合亚种)、6变种(1新变种和3新改隶组合变种)。为进一步深入开展玉兰形变理论、新品种选育和开发利用等研究提供了科学依据。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 commurlity 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 cuhivars of Y. denudata can be based on these results.
