Ivo Trinajstić ; Hrvatska

Abstract

The association Potentillo albae-Quercetum pubescentis, very interesting for the forest vegetation of Yugoslavia, was found on the locality of Bregi in the middle part of Istria, precisely, near Cerovje, north of Pazin (Croatia, Yugoslavia). Until now it has been known only from Alsace in France.
The community from Istria differs from that of France by the presence of some Illyrian, or submediterranean species (Ostrya carpinifolia, Carpinus orientalis, Sesleria autumnalis, Helleborus istriacus) and it is designated as subassociation ostryetosum.
Syntaxonomical position of the forest association mentioned is as follows:
Class: Querco-Fagetea Br.-Bl. et Vlieger 1937 Order: Quercetalia pubescentis Br.-Bl. 1931
Alliance: Quercion pubescentis-petraeae Br.-Bl. 1931 Suballiance: Potentillo albae-Quercenion Knapp 1971
Association: Potentillo albae-Quercetum pubescentis A. Horv. 1973
Subassociation: ostryetosum Trinajstic, subass. nov.
The soil, on which in Istria the ass. Potentillo albae-Quercetum pubescentis is develop, is slightly acid, brown soil above relict pseudogley on flysh basis and thus obviously showing a twoply profile.
