wards and connected with each other in a loop-line manner. The species is distributed in the Tertiary of Europe. Type II. (Figs. 48-50) (Pl. IV: 3) Material: BK1180, BK-1194, BK-1199 The shape of the lamina is wide-ellipsoidal. Base rounded, apex acute. Midrib strong, six pairs of secondary veins branching out from it. The first pairs of secondary veins at the basal part are far thinner than the others. From the secondary veins often branches are running to the margin. This branches as well as the secondary veins are terminated in the teethVenation craspedodromous. Margin toothed. The apex of the teeth are acute. The tertiary venation consists of a dense network of veins, perpendicular to the secondary veins. We can observe this venation between some secondary veins only. MONOCOTYLEDONAE Material: BK-1198 A remain with parallel venation belongs to this taxa. We can give no closer taxonomical identification on the basis of the small, insignificant piece. FLORISTIC AND PALAEOC LIMA TO LOGICAL ANALYSIS Around 18 taxa could be distinguished in the collection of plant remains from Nagysáp. Two families of gymnosperms are represented by single species each. The majority of the flora was composed of angiosperms, and those being predominantly dicotyledonous. Of the monocotyledones there was only a single leaf fragment which could be identified only to the class. Angiosperms are represented by 15 species belonging to eight families. Of these, the family Lauraceae is outstanding regarding both species number and abundance, totalling six species of two genera. One of these is Daphnogene lanceolata , with the largest number of remains (18), another important one is D. bilinica with 12 specimens, and numerous other fragments belonging to this genus. The other important family is Plataneceae which is represented by two palaeotropical species, P. neptuni and P. fraxinifolia. Of these, the latter one may be considered as a predominant species, as it is occupying the second position regarding the number of remains (13 specimens) . Regarding floristic composition, the Nagysáp locality closely resembles the nearby Kesztölc flora which is also part of the Kovacov formation. The number of Arcto-Tertiary species is very small, only Ulmus pyramidalis , and Alnus sp. belong to this group. Since these species are only represented by 2-3 specimens each, they cannot be considered as predominant. The majority of the species from this locality is thermophilous , mostly subtropical element. Here, just as at the nearby Kesztölc locality, subtropical laurel-leaved forest formed the zonal vegetation, with the predominant species Platanus neptuni, P. fraxinifolia and Daphnogene species, with less numbers of Quercus apocynophyllum , Symplocos sp. and Sa- pindus ungeri. Along rivers, in the inundation zone Ulmus pyramidalis and Alnus species occurred. Taxodium dubium indicates swampy vegetation, so its presence in the flora was either connected with wetland habitats along rivers, or it may have formed swamp forests at some distance. Because this species was found in small numbers, it may be concluded that there was no substantial swamp forest in the vicinity. A subtropical climate may be reconstructed based on the composition of the flora. As the sample sizes from the locality are too small to permit statistical analysis, only species
