Abstract: Camellia is a genus with many specics complexes interlocked each othcr.There are four subgencra and twenty sections in Professor Chang Hung Ta's (1981) phylogenetic system of Camellia. Based on the system, this paper furtherly discusses the basic principles guideing the classification of Camellia into fewer taxa and the phylogenetic relationship among them. Then Camellia is suggested to distinguish into two ancestor groups, four subgenera, ten groups and twenty sections.

Key words: Camellia

摘要： 山茶属具有复杂的种系。1958年J．R．Sealy曾将它划分为12组，亲缘关系得到一定的澄清。1981年，张宏达教授提出的山茶属系统将山茶属划分为四个亚属，20组，这一系统深刻地阐明了山茶属内各分类群的亲缘关系和演化趋向，根据这一系统，作者讨论了山茶属内的分群原则，及演化形态学，认为山茶属可以进一步归纳为两个祖群，十个群。
