英文摘要: Phylogenctic position of the monotypic genus Dipentodon has long been controversial. We investigated its,:position with 125 accessions representing 50 genera and 40 families of eudicots in the APG system. Four data sets-including the chloroplast gene rbcL, the nuclear 18S ribosomal DNA, and the mitochondrial gene matR, as well as,,,the combined matrix-were used in the study with the maximum parsimony (MP) and Bayesian inference (131) analyses. The phylogenctic trees based on individual genes and the combined data suggested that Diventodon is sister to Tapiscia (Tapisciaceae) and that Dipentodon could be placed in euroside 11 of the APG system. The clade of Dipentodon and Tapiscia is closest to Malvales and Sapindales. Such finding does not support the previously suggested close relationship between Dipentodon and various other groups, including Celastraceae, Samydaceae, Flacourtiaceae, Hamamelidaceae, and Santalales.
