"The genus Hypericum is a highly diverse group of about 500 species. Among the Eurasian taxa, Hypericum perforatum L. and H. maculatum Crantz are representative examples with a largely overlapping distribution area in Central Europe. As a medicinal plant and as a model plant for apomixis H. perforatum is a target of extended research. An important step to understand those complex processes is to illuminate the evolutionary history of H. perforatum. We were able to identify putative ancestral, fully sexual and diploid populations of H. perforatum. The H. perforatum populations were split into two major gene pools. An ancient contribution of H. maculatum or any other species to these gene pools and to the early evolution of H .perforatum could not be confirmed. However, we were able to show ongoing introgression and massive gene flow between H. perforatum and H. maculatum. The geographical patterns observed in our data showed that (i) haplotype and nucleotide diversities are very low in Northern Europe, suggesting that single haplotypes rapidly colonized large areas; (ii) genetic diversity in South Europe is higher than in North Europe, suggesting that there were refugial zones during the Pleistocene."^^ .
