We studied these phenomena in central-European populations of the Valeriana officinalis complex in order to identify mechanisms or forces driving its evolution. The complex comprises di-, tetra-and octoploid morphologically defined so-called taxonomic "types". Within the study area there are also intermediate "transitional types" the existence of which hampers the appl…
