secondary vein is 52 . This divergence of more than 10 on both sides is yielding a considerably wider leaf. While the rest of the remains enclose 80 between the secondary veins, the same value at this piece is more than 100 . In spite of this, we cannot exclude that the piece belongs equally to A

. an- gustilobum

, because the lobes are narrow, deeply incised into the lamina, the margin of the leaf is toothed. The teeth are visible on this specimen only, because the margin of the other pieces is dim. The venation is actinodromous, the secondary veins starting from the primary veins are proceeding towards the margin of the leaves not straight and rigid like in case of less toothed maples, but arching considerably upwards, forming a loop with the vein situated immediately over it. This feature, i.e., that the secondary veins do not reach the margin, is characteristic of the Acer angustilobum (HANTKE 1965, PI. 15, Fig. 8). The most significant occurrences of the species are known from the Upper Miocene (Tortonian) of Switzerland, v

the Egerian of Seifhennersdorf (GDR), Egerian and Miocene of Kundratice and Cermniky (Czechoslovakia). Its distribution known so far is confined therefore from the Upper Oligocène till the Upper Miocene. On the basis of the anatomical studies of WALTHER" ( 1972), the species belongs to the Spicata section, demonstrating a morphological similarity with the species Acer kwanqsii living in Eastern Asia (China). This latter species is a constituent of the evergreen forests at the altitude of 1300-1700 m. Acer sp. Material: No.: 76.60.1. 1 piece Description: The fossilization of the piece probably took place amidst interesting circumstances. Namely, the leaf is bent at the middle, thus the basis and the apex are situated on two different bedding planes, separated by 1 cm of sediment. In spite of the strange position of the piece, the state of preservation of the leaf is fairly good at its medial parts. Probably, the rapid flow of silt erected and preserved the piece in this unique position. The two lateral primary veins enclose an acute angle, as opposed to the A

. angustilobum

. The apical part of the leaf is fairly fragmented, still we can observe small teeth on one side of the central lobe. On some specimens of the A. tricuspidatum

, the angle enclosed by the lateral primary veins is known to be very small, however, more than 40 . Because of the fragmentary state of the piece, it could not be assigned to any species. Cornaceae Cornus L. Cornus praeamomum É. Kovács Pl. XXXIII, Fig. 3; Fig. 116. 1959 Cornus praeamomum É. Kov.; Andreánszky, p. 177, Pl. 56, Fig. 6; Pl. 57, Figs. 1-2; Pl. 58, Fig. 2. Material: No.: 76.112.1. 1 piece Description: A large, fragmented piece, the basis is completely missing. The apex is acute. The original total length of the leaf could be around 15 cm, its width is about 6.4 cm. The secondary veins are running arched towards the apex, characteristic of the Cornus species in general. The margin of the leaf is entire. Around the midvein, the leaf is injured at the lower parts, thus the distance between the starting points of the secondary veins cannot be measured. The angle of divergence observable on the leaf, however, let us suppose that the distance between the veins is gradually increasing towards the apical parts, which is also fairly typical of the Cornus genus. 35
