Abstract. This phylogeographical study concentrates on five species representing the Pontic-Pannonian subelement of the Polish flora: Carlina onopordifolia Besser ex Szafer, Cirsium pannonnicum, Inula ensifolia (L. fil.) Link, Linum flavum L. and Linum hirsutum L. Material was collected from populations in the following geographical regions of Central and Eastern Europe: the Wyzyna Malopolska upland (Poland), Wyzyna Lubelska upland (including Volhynian Polissya and the western part of the Volhynian Upland, Poland), the Podolian Upland (Ukraine), the southern (Hungary, Romania) and northwestern (Czech Republic, Slovakia, Austria) parts of the Panonnian area, the Balkan Peninsula (Bulgaria) and the northern Adriatic coast (Italy, Slovenia). The aim of the study was to verify hypotheses regarding migration routes, the time of migration of these species to southern Poland and more broadly to Central Europe, and the historical role of eastern and southern Poland in these processes. The 1434 samples collected in this work were analyzed after amplified fragment length polymorphism genotyping. Genetic variation was analyzed on the level of populations, population groups from specific geographical areas, and all sampled populations per species. The level of genetic variation was determined based on Nei''s gene diversity index, Shannon''s diversity index, frequency- downweighted marker values, and the number of polymorphic, private and discriminating bands. To test for isolation by distance between populations, the correlations between pairwise F ST and geographical distances, were examined with the Mantel test.
