IV. (Polygonato latifolio-Quercetum roboris BORHIDI in BORHIDI et KEVEY 1996) Abstract: I studied the closed oak forests in the sandhill area of the Bakonyalja, the western foothills of the Bakony Mountains, where I collected 10 vegetation samples. The studied stands typically occur in intermediate ecological situation between Turkey oak forests (Asphodelo-Quercetum roboris), which grow on drier soil and higher ground, and oak-hornbeam forests (Corydali pumilae-Carpinetum

) growing in the depressions between sand dunes. Accordingly, they host a lower proportion of species characteristic of dry oak forests (Quercetea pubescentis-petraeae) and a higher proportion of species characteristic of mezophilous broadleaved forests (Fagetalia) than those of Turkey oak forests. Results of conventional and multivariate analyses show that the species composition of these forests are most similar to that of the closed pedunculate oak forests in the Mezőföld (Polygonato latifoliae-Quercetum roboris), and thus are identified with them. Keywords: Syntaxonomy, closed oak forests on sand, cluster analysis, ordinatio. 1 A kutatásokat a Bakonyi Természettudományi Múzeum és a „TÁMOP 4.2.2.A-1 l/l/KONV-20120004" pályázat támogatta. 55
