Abstract (in english)
   The large number of shared plant genera in the Oligocene of Europe and North America indicates that migration between these continents was possible at some time during or prior to the Oligocene. Identical or closely related species shared between Europe and North America and apparently absent from Asia in the Oligocene (c.g. Tetraclinic salicornioides, Cercidiphyllum crenatum, Ostrya oregoniana/O. atlantidis, Mahonia simplex/M. bilinica, Cedrelospermum lineatum/C. leptospermum, Saportaspermum occidentale) indicate that floristic exchange around the North Atlantic may have continued even during the Late Paleogene. Some of the Palaeogene elements of sclerophyllous subhumid vegetation of the Old Mediterranean (Tethys and Paratethys) and Madrean provinces are partly endemic to the separate regions and corroborate the view that southern areas of the Holarctic flora were more isolated at that time
