Fagaceae Quercus L. Quercus cf. seyfriedi A. Braun ex Heer, 1856 (Pl. 23, fig. 3) 1856 Quercus seyfriedi A. Braun; Heer, pl. 75, fig. 17. Material; 86.504.1. Description: Basal fragment of the leaf preserved. Apex absent, base acute, margin entire. Midvein strong, venation camptodromous. Secondary veins are thin, connect with each other near the margin, forming a curly, more or less parallel line with the margin. More thin veins branch out of the secondary veins, forming an other loop-system. Discussion: The remain is very similar to Q. seyfriedi A. Br. in Heer (Heer 1856, pl. 75, fig. 17). Without more specimens and cuticle we can not be sure in its systematical position. Quercus elaena Unger sensu Heer, 1859 (Pl. 9, figs. 2, 3; Fig. 35) 1859 Quercus elaena Unger; Heer, pl. 151, figs. 1—3. Material; 86.501.2., 86.502.2., 86.503.1., 86.506.1., cf.86.518.2., 86.624.3., 86.626.1., 86.641.2., 86.643.1., 86.644.2., 86.653.1. Description: 8.5 - 9.0 cm long, 1.5 - 2.4 cm wide leaves. Shape lanceolate, apex and base acute, margin entire, venation camptodromous. Midvein strong, secondary veins are running out of midvein in regular distance from each other. Near the margin they are connected with each other forming a crenate line parallel with the margin. Discussion: The remains are similar to those on the figures of Heer (1859), pl. 151, figs. 1-3. The venation is very characteristic, so, we can distinguish even the small fragments of the leaves. cf. Quercus neriifolia A. Braun sensu Heer, 1856 (Pl. 5, figs. 4,5; Pl. 9, fig. 5) 1856 Quercus neriifolia A. Braun; Heer, p. 45, pl. 75, fig. 2. Material; 86.407.2., 86.408.2., 86.409.1., 86.410.2., 86.411.2., 86.412.2., 86.413.2., cf. 86.414.2., 86.460.2., 86.509.2., 86.510.1., 86.515.1, 86.516.1. Description: 6.0 - 10.0 cm long, 1.3 - 2.4 cm wide, simple leaves. Shape lanceolate, apex and base acute, margin entire. Venation camptodromous, midvein strong, secondary veins are thin and run out of the midvein in acute angle. Discussion: Lanceolate leaves with entire margin and camptodromous venation belong into this group. Without any significant character and cuticle, their systematical position is uncertain.
