Daphnogene cinnamomifolia (Brong. in Cuvier) Unger - HABLY, p. 90 Material: MÁFI: BK­1178, BK-1196, BK-1197, BK- 1308, BK- 1320, BK-1321 Large leaves, though in this locality (in general) basal fragments has been found only. Laminae elongated, obovate. Base and apex acute, margin entire. The midvein and the basal veins are strong. Nervatio suprabasal, imperfect. The basal veins run between the midvein andUhe margin at the same distance in the lower part of the lamina, in the apical section they approach the margin more closely. Between the basal veins and the margin, the tertiary venation starts at an acute angle, and then curves loop-wise. At the apical section the second­ary veins starting from the midvein, also form loop connections. Tertiary veins run in the form of a reversed V between the midvein and the basal veins, and form anastomoses. This species is characteristic of the Oligocene/Miocene boundary. In Hungary it has been found in the Egerian stage at many localities, as well as in the Lower Miocene flora of Ipolytarnóc. Daphnogene lanceolata Unger (Figs. 18-30) (Pl. I: 3, 4 and Pl.

Length of the leaves varies between 4.2 and 8.8 cm, their width is 1.25-2.8 cm. Leaf margin entire. Base acute, apex acumi­nate, ending frequently in a drip-point. The midvein is strong, the basal veins are thinner than the midvein. Nervatio suprabasal, perfect. The basal veins and the secondary veins start from the midvein to form a loop. The species is characteristic of the Upper Oligocène in Central Europe. In Hungary it has been found in the Egerian stage at many localities. a 5
