Abstract: | Studies of the beeches and beech woods of eastern central Europe revealed, that in the postglacial period not only Fagus sylvatica (L.) emend. reimmigrated from the refugial territories in the SE-as has generally been accepted, but also the transitional taxa, which originated from hybrids with F. orientalis Lipsky. The NW area limit of these intermediate taxa must be revised. The presence in central Europe of these taxa-which form own Fagion alliances and associations in the SE (Fagus intermedia ssp. moesiaca and ssp. taurica) as well as the presence of other southeastern species in central European beach woods shows, that their postglacial development is parallel to, but different from other areas. The taxon Fagus intermedia (ssp. neglecta and ssp. transitus) became differential taxa of a central European region of the Fagion medioeuropaeum. Plant sociologists are therefore requested to make new and critical analyses of the beech woods in Europe, with special attention to the Fagus taxa, in order to establish in detail the geographical distribution and phytosociological significance of Fagus intermedia.The author offers to determine or revise Fagus material (herbarium collections).
