The paper uses statistical methods to examine whether origination from different Pleistocene centers influences the present-day variation of Carpinus betulus in Poland. Twenty-nine populations of the species were sampled in communities of the Carpinion betuli alliance in most of the country. Samples of 100 involucres for each population were analyzed for 26 morphological characters. Despite the rather accidental similarities among the sampled populations, their geographic variation confirmed their origin from at least two different refugia, southeast and west.
Key words: Carpinus betulus, involucres, morphology, plant geography, plant variation, Holocene migration, migration pathways.
