ANACARDIACEAE Rhus s p. Asymmetrical leaves, petiole is not observable. Shape lanceolate. Lamina length 4.2-4.9 cm, width 1.7-2.3 cm. Apex attenuate, base presumably obtuse. Margin is toothed. The teeth are acute and both of their apical and basal sides are convex. The sinuses are angular. Venation craspedodromous. The course of the midvein is curved. The secondaries arise at acute angle. Their course is curved and they run into the teeth. Some of them have a vein branching from the lower side of the secondary veins and it runs into a sinus. The tertiary venation cannot be observed.

RUTACEAE Pteleaecarpum europaeum (BRONN 1838) BUZEK et KNOBLOCH in KNOBLOCH 1969 1856 Ptelea macroptera Kov.: KOVÁTS, p. 51, Tab. 1, Fig. 2. 1959 Ptelea macroptera Kov: ANDREÁNSZKY, p. 151. 1971 Pteleaecarpum europaeum (BRONN) BBZEK et KNOBLOCH in KNOBLOCH: BBZEK, p. 70, PI. 31, Figs 1-21. A fragment of a fruit. Its length is 2.8 cm, width 0.9 cm. The seed is in the middle of the samaroid fruit. A thin venation is recognizable on the outer paît of the fruit. Material: No. 451c. LAURACEAE Lauraceae gen. et sp. Some symmetrical leaves which have relatively thick petiole. The leaves are thick and coriaceous. Shape narrow elliptic. Lamina length 4.6 cm, width 1.5-2.8 cm. Apex acute, base acute. Margin entire. Venation camptodromous, brochidodromous. Midvein straight. The secondaries arise at acute angle (60°) and they do not reach the margin. They anastomose with each other at acute and right angles and form loops. The tertiary venation is thin and hardly visible. Presumably its pattern is random reticulate. Material: No. 270, 335a, 365, 536a. Laurus sp. Symmetrical leaf with relatively long petiole. Lamina length 3.4 cm, width 1.2 cm. Shape narrow elliptic. Apex presumably acute, base cuneate. Venation camptodromous, brochidodromous. Midvein straight. The angle of divergence of the secondaries is acute (45°-50°). The neighbouring veins anastomose at right angle and form loops. The tertiary venation is reticulate. Material: No. 268. cf. Daphnogene sp. One badly preserved, small leaf. The apex and the base cannot be observed. The base must have been acute. Lamina length 1.1 cm, width 0.7 cm. Margin is entire. Venation seems to be acrodromous. Midvein is weakly curved. A strong, basal pair of veins arises from the base. The angle of divergence of the secondary veins is acute. The tertiary venation is not observable. Material: No. 133a. ARALIACEAE Araliaceae gen. et sp. I. One fragmented, badly preserved leaf. Only its base has remained (without the petiole). Presumably it was
