However, interspecific relationships were not well resolved or supported. In this study, we employed sequences of nrDNA ITS and chloroplast gene matK and intergenic spacer psbA-trnH to examine interspecific relationships and infer the character evolution and biogeographic history of Wisteria. Our results show that North American species of Wisteria form a sister relationship with the eastern Asian species. In the Asian clade, Wisteria brachybotrys of Japan is sister to the clade containing W. floribunda of Japan and Korea, and W. sinensis, W. villosa, and W. brevidentata of China. Sequences vary little among the three Chinese species and there is no well-supported phylogenetic structure, recognizing them as a single species. Our Fitch parsimony analysis suggests that Wisteria sinensis of the continental Asia may have derived from ancestral populations from Japan via Korean Peninsula. Both clockwise twining in W. floribunda and erose leaf margin in W. sinensis are more derived features within Wisteria.} }
