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
