浙江桂及其相近种的亲缘关系及分类等级探讨

AN APPROACH TO THE RELATIONSHIP AMONG CINNAMOMUM CHEKIANGENSE AND ITS ALLIES

  • 摘要: 浙江桂、普陀桂和日本桂(天竺桂)是樟属植物中的三个相近种。六十多年以来,围绕着它们的亲缘关系及其分类等级,植物学界展开了反复的讨论,至今仍然存在着较大的分歧。在文献考证的基础上,笔者通过赴模式产地考察与采集鉴定,从比较形态学、扫描电镜观察、种子油脂成份的化学分析和地理分布区等方面,进一步研究了这三个种的异同,认为浙江桂是中国大陆的特有种;普陀桂应当归并入日本桂,作为一个变种处理;日本桂的原变种在中国仅见产于台湾省,而在大陆并无自然分布。

     

    Abstract: Cinnamomum chekiangense Nakai, C.chenii Nakai and C.japonicum Sieb. are closely relative plants. The argument on their relationship has been discussed for more than 60 years and no definete conclusion are gotten The authors had taken a series of research work, including the review of some original literatures, the examination of the herbarium specimens, and the expedition to the type localities——the Putuo Mountains and Hangzhou. We had collected so many fresh materials, such as leaves, berries and specimens,and had taken the phytogeographical and morphological studies, and the chemical analysis of the seedoil, and the application of electron microscope. The results confirmed the au-tthorst belief that C.chekiangense is a indigenous species to Central and Eas China, and C.chenii should be put down under the name of C.japonicum as a variety——C. japonicum Sieb. var. chenii (Nakai) G.F.Tao, stat.nov., which is considered as an endemic species of the Putuo Mountains in Zhejiang Province, China. As for C.japonicum var. japonicum, it has a distribution ranging from Japan and Korea to Taiwan. A full description of above-mentioned plants is given in this paper.
