| Outline of Final Research Achievements |
Molecular phylogenetic analysis of Japanese Salvia, detection of pollinators, and sex expression of each Japanese species of subgen. Allagospadonopsis, Salvia (Lamiaceae) were conducted. Phylogenetic analysis revealed that S.lutescens var. intermedia was polyphyletic group, and needed to be revised taxonomically. Further phylogenetic analysis enlarged to East Asian Salvia together with Chinese collaborator clarified that S.japonica and S.pygmaea were more closely related to Chinese allies, not to Japanese ones. Other Japenese endemics formed a highly supported clade, apart from Chinese allies in the tree, suggested monophyletic origin of those endemics. Japanese endemics may be speciated allopatrically, and S.japonica and S.pygmaea enlarged their distribution to Japan after Japanese endemics were speciated.
Additional population analyses clarified that S.japonica has been hybridized with other Japanese endemics, S.lutescens var. intermedia.
