Ulmus plurinervia Ung Pl. XX, Fig. 3. 1847 Ulmus plurinervia Ung, 1980 Ulmus plurinervia Ung, Fig. 7: 4-11. Unger, p. 95, PI. 25, Figs. 1-4, Zastawniak, p. 58, PI. 2, Figs. 3-5; Material: No 6 pieces 76.98.1.; 76.101.1.; 76.111.1.; 76.132.1.; 76.233.1 76.299.1, Description: Very small leaves, their length is smaller than 5 cm, and their width is less than 2 cm. Their shape is narrow ovate, the apex is acute, the basis is cordate. In case of most pieces the basis is fragmented, thus this feature can be observed only in a few instances. The secondary veins are starting densely from the midvein. They are straight, rigid and form no arch or curvature. The distance of the veins are demonstrated on a graph (Fig. 141). Apparently after a slight rise the row of dots is gradually declining. The formation of the angle of divergence is presented on a graph. Palaeobotanical literature refers to these Ulmus leaves as U. plurinervia, U. bronnii

, U. minuta

. The margin of the leaves is very poorly preserved, thus the toothing of the leaves cannot be evaluated.

Similar leaves were found in the Upper Oligocène flora of Pomáz (HABLY, under elaboration), the state of preservation of which is essentially better than that of these. Considering that they are occurring here, as well as at Pomáz, together with numerous leaves of Ulmus pyramidalis

, we cannot exclude the possibility that they belong to the same species as smaller and bigger leaves. It is possible that we are dealing with size differences between leaves situated at different parts of the sprout axis. Anyway, the U. plurinervia occurs at more sites of the Egerian, comprising more specimens, in general, only in minor quantities.
