Their greatest width is reached in the upper third of the leaf, thus their shape is obovate, generally elongated obovate. In the Vértesszőlős flora two types of the species could be differentiated, with transitionary forms between them. The first type is wider, mesomorphic in character, e.g. 76.195.1, 76.8.1., 76.194.1. and an intensively elongated narrow type like 76.161.1., 76.188.1 (4 pieces) and 76.195.1. All of them have an obovate form and the character of the vein system is similar. The basal veins which are very strong are branching off in a V-shape from the midvein, that is, getting gradually further from it towards the apex. In the upper third of the leaf, at the widest point, they are forming a loop with another considerably strong pair of secondary veins starting from the midvein

. 'Their further loop-like connections can be traced till the apex. Between the midvein and the basal veins there is a nearly horizontal system of tertiary veins, while towards the margin, veins from the basal veins can be observed, arching upwards. In case of these veins, however, the formation of loops can be observed very rarely, only in the upper half of the wider type leaves. D. bilinica was found in Hungary at the Verőcemaros site as well, also in Egerian layers. In the neighbouring countries (Czechoslovakia, Romania, GDR) it is widely distributed in the Upper Oligocène, though according to the system of KVACEK and WALTHER (1974) it is more typical for the Miocene. Apart from their frequent occurrence in the Miocene, they are dominant elements at some places already in the Upper Oligocène, e.g., in Hungary. In the Egerian of Central Europe it can be found mainly among the Arctotertiary elements already. In the Vértesszőlős and Verőcemaros floras the species used to live among subtropical conditions, in case of Vértesszőlős, among considerably humid climatic relations. In the latter flora it can be considered as dominating species due to its great individual number. 12
