Outline of Final Research Achievements

In order to clarify allopatric speciation process in the continent marginal area, the phylogeographic analyses using Pedicularis (Orobanchaceae) species were conducted. Through the studies, we were able to obtain the following outcomes. The central Honshu clade of P. chamissonis has been the endemic species that originated in Japan (Fujii et al. 2013). P. yezoensis were differentiated at least three major clades in Japan (Hokkaido, Tohoku, central Honshu clades). Relict distribution in Mt. Hakusan, Ishikawa Pref., was clarified in P. spicata (Fujii et al. 2014). The population of P. refracta, endemic to Kyushu region, were made monophyletic group with those of ser. Verticillata species in Taiwan.
