The leaf DNA samples of 29 species of Sect. Camellia in Camellia were extracted and analyzed, using random amplified polymorphic DNA （RAPD） genetic markers. 23 selected primers were used for DNA amplification. The amplified polymorphic DNA bands were translated into 0 - 1 data, and then, correlation analysis and clustering analysis were done for processing data by using UPGMA method. The results indicated that 29 species of Section Camellia should be grouped under four clusters, that is, Subsect. Lucidissima, Series Chrysanthae and Series Reticulata, moreover, C. glabsipelata was taken as a sole cluster. Series Chrysanthae and Series Reticulata composed Subsect. Reticulata. The results were in agreement with the views of Zhang Hongda＇ s taxonomy. Based on similarily coefficient between each other, 3 varieties groups with close genetic relationship were discovered in Section Camellia.
