The Vandenboschia radicans complex, one of the 'cosmopolitan species' of pteridophyte, shows great morphological variation within the Japanese Archipelago. The study by Ebihara et al. (2005) which clarified the complicated origin of this complex resulted from reticulate evolution also revealed that the Pacific coast of the Kanto region possesses the most diversified genomic-formula. In this study, we focused on the V. radicans complex of the region (Izu, Miura and Boso Peninsulas) by enriching samples, and discussed possible causes for the diversity. Of the three peninsulas, Miura Peninsula exhibits particularly diversified genomic formula in spite of less variable alleles and narrower distribution range than the other two. These results suggest that the present populations of Miura Peninsula have been locally formed by reticulate evolution based on limited number of ancestral lineages.
