APPLICATION OF GREGOR'S METHOD TO THE FOMÁZ FLORA J. Gregor (1982) elaborated a method for evaluation of the Neogene leaves. This method is well applicable for the Egerian floras of Hungary, since they display much similarity to Early Neogene floras both in composition and morphology. Gregor (1982) established 23 leaf types on the basis of leaf margin and shape. Naturally, this classification is not quite independent from the conventional taxonomy. The type groups are lettered a to x. Abundance (number of specimens) is also taken into account and indicated by numbers on a 4-degree scale: 1 most common elements (more than 100 specimens) 2 common elements (11 to 100 specimens) 3 rare elements (2-10 specimens) 4 single specimen Using this code, a table can be edited for any locality, showing the abundance of the different leaf types. (Of course, this method is applicable only to floras consisting of more than 100 specimens).

Gregor (1982) also gave the character (deciduous or evergreen) of each leaf type. Accordingly, the Egerian Pomáz flora is dominated by a = cinnamomoid = evergreen, b = lauroid = evergreen, e = myricoid = evergreen and thermophilous deciduous (including Platanus fraxinifolia, P. neptuni, Palaeocarya orsbergensis), h = leguminosoid = deciduous, m = carpinoid = deciduous, i = quercoid = deciduous and evergreen elements. The flora consisted of thermophilous (mainly laurophyllous) Paleotropical species. The only Arctotertiary group is the m (carpinoid), represented mainly by Ulmus pyramidalis. Application of GREGOR' s method supports my earlier view on the character of the flora and vegetation (Hably 1992, 1992a). It confirms that subtropical, laurophyllous forests prevailed in the Egerian, mixed with some thermophilous deciduous species.
