Description: There were only two leaflets of the leaf remaining, among them, the central one is complete, only covered by, on the basal parts, a bit of the right side leaflet. The margin of the leaflets is enlire. The veins of the secondary order are hardly visible, spotted sometimes in the vicinity of the midvein only. Their angle of divergence is larger than 60 . The length of the central leaflet is 9 cm, its width is 2 cm. The side leaflet is fragmented, probably it was shorter than the central one. The two leaflets meet without any petiole, thus they were probably placed very near to each other. This is the reason for their position, i.e., covering each other to some extent. The form of the leaflets is elongated elliptic, their basis and apex is acute The species was encountered at the Egerian flora of Verőcemaros for the first time, described by HABLY (1982). The age of the two finds therefore is equal, however they come from different lithostratigraphical formations. Besides the D. hungarica , at Verőcemaros we can find the plants present in the Vértesszőlős flora, i.e., Platanus neptuni , Daphnogene, Ulmus, Acer species . Still we cannot draw an immediate relation between the flora of Vértesszőlős and Verőcemaros, because the difference in the individual- and species number of the two is so large that it might lead to serious errors as well.

Their length is ranging between 8-12 cm, their width is between 4.8-7.4 cm. The proportions of the lamina is 1.6-1.8 cm, that is, between the wide and narrow obovate. The apex is fragmented at all specimens. The basis of the leaves is obtuse, the margin entire. The vein system is camptodromous. In the continuation of the secondary veins, there are further loops formed towards the margin. At the intersecondary area we can observe a relatively dense network of tertiary veins. The tertiary veins are basically perpendicular to the secondary ones. In between the veins, however, anastomoses can be formed, even branching. The distance of the secondary veins from each other is partly depending on the size of the leaf, but anyway, it is smaller at the basal parts than at the medial region. The distance between the veins is typically around 1 cm at most specimens, only at the holotype we find this value around 1.5 cm or over it . The angle of divergence of the secondary veins is one of the most characteristic features of the species. 76.20.1. Holotype. The angle of divergence of the secondary veins, measured from the basis till the apex is as follows: left side: 76 58 51 37 31 right side: 65 65 58 50 44 42 76 12.1. left side: 59 52 42 37 37 right side: 58 50 47 43 40 37 7 6 307.1. left side: 74 65 60 51 48 42 right side: 76 68 67 58 55 47 59
