The article presents taxonomic study carried out in 3 pedunculate oak populations in Slovenia by leaf morphometry and DNA analysis with RAPD markers. About 100 leaves were sampled from 5 trees from 3 seminatural pedunculate oak stands in the Sub-Pannonian vegetation region of Slovenia. Samples were collected from the well-lit upper part of tree crowns, and only leaves from short twigs were analysed. Leaf samples were herbarised, and measured and assessed in laboratory. Leaf dimension (lamina length and width, petiole length, number of lobe pairs), leaf pubescence and leaf lamina base type show that all sampled trees belong to the Quercus robur L. species. Nevertheless, on some trees, leaves also show characteristics typical of sessile oak (Quercus petraea /Matt./ Leibl.), especially the leaf lamina base type and number of lobe pairs. Other analysed parameters were within the variation of pedunculate oak. More populations of both oak species need to be analysed to obtain reliable data.
