East Asia is characterized by high levels of species diversity and endemism. However, the biogeographical patterns and processes underlying the distribution of biodiversity within the area are still poorly known. In this study, we used plastid (matK,trnL-F, andtrnH-psbA) and nuclear (ITS) DNA sequences to investigate the historical biogeography ofDichocarpum(Ranunculaceae), an eastern Asian endemic genus throughout warm-temperate and subtropical forests of the area. Phylogenetic analyses strongly supportDichocarpumas monophyletic, which contains two major clades. Clade I corresponds to sectionHutchinsonia, and clade II includes sectionsDichocarpumandFargesia. SectionDichocarpumand its subsectionsDalzieliaandDichocarpumare not recognized as monophyletic. Our results suggest that the most recent common ancestor ofDichocarpumoccurred in central China and Japan in the earliest Early Miocene, and thus support an ancient vicariance event between Japan and China. Within mainland China, three migrations at the species level were hypothesized to explain the expansion ofDichocarpumfrom central China to southeastern Yunnan, Hengduan mountains, and eastern Himalaya. These migration events occurred in the Late Miocene to Early Pliocene, which may be associated with the uplift of the southeastern Qinghai-Tibetan Plateau and accordingly the expansion of subtropical forests in China around that period. A migration or dispersal from central China to Taiwan was inferred in the Early Pleistocene, which supports the close floristic affinity between Taiwan and mainland China. This study contributes to our knowledge on the historical biogeography of plants in eastern Asia.
