| Research Abstract |
This study aims to clarify the process of speciation on the local endemic species which might be derived from widely-distributed species in Potentilla fragarioides group (Rsoaceae) . 11 species in the Potentilla fragarioides group were analysed.As a result, it is clarified that 1) all the species in the P. fragarioides group are diploids (2n=14), 2) P. freyniana var. sinica is not merely a variety of P. freyniana, but it is a clearly independent species, 3) although P. yamanakae has been treated as a hybrid, it has turned to be a good species, 4) two hybrids, hybrid between P. koreana and P. fragarioides, and between P. riparia and P. yamanakae, are discovered.
