Bû£, HOLY and KVAC.; Hably p. 101, pi. 17, fig. 6; pi. 18, figs. 1-6; pi. 19, figs. 1-5; pi. 20, figs. 1-4; pi. 21, figs. 1-3. Material: sample No 863, depth 1738.0 m, No 863, depth 1743.5 m, No 863, depth 1745.0 m Simple leaves, 3.8-5.5 cm in length, 1.1-1.9 cm in width, some of them with petiole. The basis of the leaf is asymmetrical. The venation is camptodromous. The margin of the leaf is toothed at the upper two-third of the lamina and entire at the basal parts. The teeth are simple, their apices are obtuse, set relatively far from each other. The sinuses between the teeth are rounded.The species is typical of the Upper Oligocene/Lower Miocene boundary of Hungary. It is abundant in the Hungarian localities of the Egerian Stage as well as in the Lower Miocene flora of Ipolytarnóc (Hably 1985, 1988, 1989, 1990). Unlike the other known species of Platanus, this species is a Palaeotropical element, different in ecological and climatological respects. Ulmaceae Ulmus L. Ulmus ci. pyramidalis GOEPPERT Pl. IV, Fig. 2. 1988 Ulmus pyramidalis GOEPP; Hably, p. 41, pi. 9, figs. 2-3. Material: sample No 863, depth 1743.5 m, No 863, depth 1744.3 m The material consists of marginal or basal fragments. The venation is craspedodromous, the secondary veins terminate in the main teeth while small branchoff veins are heading towards the side teeth. Teeth are compound. The species is distributed almost everywhere in the Upper Oligocène - Lower Miocene of Hungary, forming the only Arctotertiary element occurring in abundance in the Egerian Stage (Hably 1988,1989, 1990). At the Lower Miocene locality of Ipolytarnóc, it is known to occur frequently from the sandstone bearing footprints (Hably 1985). There U. pyramidalis is the only abundant Arctotertiary species. The Iharosberény-I borehole also yielded this species, in the deeper level composed ma-
