inly of Palaeotropical elements, as the only Arctotertiary species. Its appearance in the Palaeotropical assemblages is related to the fact that it often lives in extrazonal assemblages as a high riparian plant, thus it could penetrate, following the courses of waterflows, deeply into regions lying outside of its climatic zone.

Material: sample No 883, depth 1779.1 m The apex is acute. The total length of the leaf could be approximately 5.6 cm, the measurable length is 4.2 cm and the width is 2.6 cm. The margin of the leaf is simply toothed. The teeth are large, regular and simple; their apical side is convex and shorter than the basal side which is also convex. In Hungary the species is known to occur sporadically since the Late Oligocène. It was found as a dominant element in some Sarmatian floristical assemblages (e.g., Erdőbénye (Andreánszky 1959)).
