Morphological studies and molecular phylogenetic analyses have recognized three tribes in the tea family (Theaceae).However, relationships among the three tribes need further testing.In addition, it has been controversial whether to recognize Stewartia and Hartia as two genera or one genus.Each of the tribes shows a disjunct distribution between eastern Asia and North America.In this study we used ca.40,000 base pairs of chloroplast genes to gain a better understanding of the phylogeneics and biogeography of Theaceae.Our results provided strong support for the three tribes in the family: Theeae, Stewartieae, and Gordonieae, and further recognized the basal position of Stewartieae.Our data support the combination of Hartia and Stewartia.Divergence times of eastern Asian-North American disjunct taxa (Franklinia and Schima in Gordonieae and Stewartia ovata and S.malacodendron of North America and Asian species of Stewartia and Hartia in Stewartieae) were estimated to be the Mid-Miocene, which agrees with recent estimates of the disjunction in other angiosperm taxa.
