ANGIOSPERMATOPHYTA ULMACEAE Ccltisjapeti UNGER 1852 1959 Celtis japeti UNG.: ANDREÁNSZKY, p. 135. 1987 Celtis japeti UNGER: PALAMAREV & PETKOVA, p. 58, Tab. 15, Fig. 2. One leaf fragment with petiole. Lamina asymmetrical. Shape narrow ovate. Lamina length 3.1 cm, width 1.6 cm. Apex is attenuate and base is asymmetrical rounded but approaching the midvein it becomes decurrent. Margin cannot be observed. Venation semicraspedodromous or brochidodromous (it is not determinable). Midvein weak and straight. A pair of basal veins nearly as thick as the midvein arises from the base. A vein seems to branch off basally from the latter veins towards the margin. The angle of divergence of the secondaries is acute (45°-60°-70°). Toward the apex they are getting thinner. Their course is curved and they do not reach the margin. Tertiary veins arise at angles of about 60° and the neighbouring tertiaries anastomose with each other at obtuse angles. M a t e r i a 1: No. 271. Ulmus plurinervia UNGER 1843 1856 Ulmus plurinervia UNG.: KOVÁTS, p. 26, Tab. 4, Figs 6-7. 1959 Ulmus plurinervia UNG : ANDREÁNSZKY, p. 129, Tafel 34, Fig. 4, Tafel 36, Figs 5, 7. Only one leaf was found. It is badly preserved and the petiole is hardly observable. Lamina symmetrical, shape narrow ovate. Lamina length 3.4 cm, width 2.0 cm. Apex acute, base cordate. On the margin there are compound teeth. Under the main teeth small secondary teeth are also observable. The apical and basal sides of the teeth are convex. All the teeth are attenuate. Venation craspedodromous. The midvein is straight and the secondaries arise at acute angle. Approaching the margin they bifurcate and the lower ones run into the secondary teeth. Due to the fossil's bad condition the tertiary venation is not observable. M a t e r i a 1: No. 69b. Ulmus sp. One leaf fragment. Only the lower part of the leaf has remained. Lamina length 6.0 cm, width 2.4 cm. Shape must have been narrow elliptic. Base asymmetrical and obtuse. The margin is toothed. Because of the bad condition of the leaf the teeth cannot be described precisely. Presumably they are compound teeth. Venation craspedodromous. The course of the midvein is straight. The angle of divergence of the secondaries is acute. The veins are straight and run into the teeth. The tertiary venation is extremely thin and its pattern is orthogonal reticulate.

Pl. 2 Figs 1-3, 5, Figs 19, 23. The species is represented with a great number of leaves which have petiole. Lamina asymmetrical. Shape lanceolate. Lamina length 1-7.4 cm, width 0.6-3.3 cm. Apex attenuate, base obtuse. Margin regularly and simply toothed. The teeth are acute. The apical side of them is acuminate, the basal side is convex. The sinuses between the teeth are angular. Venation is craspedodromous and the midvein is straight. Secondaries arise at acute angle (50°-60°) but in the upper pail of the leaf the angle of divergence is growing. Their course is curved and they run into the teeth. Smaller veins are observable, arising from several secondary veins toward the margin and running into the sinuses under the tooth that belongs to the secondary vein. The tertiary venation is extremely thin. They arise at right angle and several of them bifurcate and anastomose with the neighbouring tertiary vein. The quaternary venation is orthogonal reticulate.
