The present study presents the associations of hornbeam-oak forests (Scillo vindobonensi-Carpinetum)
in the northwestern part of Hungary based (Hanság) on 50 cenological images. We are
faced with an azonal association moderately influenced by groundwater. Some submontane
elements are striking in their stocks, which are generally rare in the Great Plains.
In particular, Fagetalia elements are common: Actaea spicata, Adoxa moschatellina,
Aegopodium podagraria, Allium ursinum, Anemone ranunculoides, Asarum europaeum, Athyrium
filix-femina, Carex pilosa, Carex sylvatica, Circaea lutetiana, Corydalis cava, Corydalis
pumila, Epipactis helleborine agg., Gagea lutea, Galanthus nivalis, Galeobdolon luteum,
Galium odoratum, Hedera helix, Listera ovata, Milium effusum, Pimpinella major, Polygonatum
multiflorum, Pulmonaria officinalis, Salvia glutinosa, Sanicula europaea, Scilla vindobonensis,
Stachys sylvatica, Vinca minor, Viola reichenbachiana etc. These plants are probably
remnants of the former "Beech I period" (2500 BC to 800 BC) with cooler, wetter and
more even climates.
