The species was described from the Badenian flora of Nögrádszakál, Hungary (KOVÁCS 1959 in ANDREÁNSZKY 1959), where 14 specimens were found. Their dimensions were changing amidst fairly large intervals, however, they are generally large. The recent equivalent of the species, according to Kovács, is the species C. amomum , which is a widely distributed plant of the North-American marshy regions. Cornus cf. wrightii Knowlton Pl. XXXIV, FigT 2. 1899 Cornus Wrigtii Knowl.; Knowlton, p. 749, PI. 103, Fig. 4. 1974 Cornus Wrigtii Knowl.; Bajkovskaya , P- 93, PI. 23, Figs. 1, 6. Material: No.: 76.129.1(2) 2 pieces Description: One of the leaves is narrow elliptic, the lamina is getting narrow towards the apex and the basis. The apex is acute, probably, the basis is also acute but it is fragmented. The length of the leaf is 8 cm, its width is 3.4 cm. The widest point of the lamina is somewhat below the medial line. Because of the fragmentary state of the basis, the position of the widest point cannot be exactly determined. There are only three pairs of secondary veins visible on the piece, placed fairly distant from each other. The distance between the first two veins is 1.8 cm, between t+ie second and the third veins, 1.9 cm. 1.3 cm far from the apex we find the highest secondary vein, thus - typical of the Cornus - there are no further secondary veins starting at the apical region. The divergence of the veins is arched, the most intensively curved pair of veins being the highest one, while the other two pairs are less intensively curved. The margin of the leaves is entire. The form of the print is very similar to that of the species Elaeocarpus palaeolanceolatus Kolak., though that one is more elongated and its leaves are more narrow, and the system of the secondary veins is more densely set. Another important difference can be observed in the angle of divergence of the secondary veins, which are steeper in case of the E. palaeolanceolatus , forming a loop near the margin, thus their system is camptodromous . In case of the Vértesszőlös flora, the connection of the secondary veins can be observed at the other specimen of C. wrightii as well. The veins here are much more arched than those of the E. palaeolanceolatus and also more sparse. The latter specimen is smaller than the other one, its width is 2.4 cm, its length cannot be established due to the lack of the apex as well as the basis. On this specimen, the tertiary venation connecting the secondary veins is visible at some places. Cornus sp . Pl. XXXIV, Fig. 1; Fig. 121. Material: No.: 76.4. 1.(=76.32.1.counterpart ) 1 piece Description: The form of the leaf is obovate, its length is 8 cm, width is 3.6 cm. The distance of the secondary veins are fairly large, similar to the other two Cornus taxa, namely: 1.15; 1.3; 1.7 cm. The secondary veins are running towards the margin in a wide arch, that is the angle of divergence is relatively wider than in case of the other Cor nus species. The sparse vein system running towards the very edge of the margin renders it similar to C. wrightii , the form of the leaf, however, is different. The state of preservation of the print is not so good that we could exactly determine the correct taxonomical position. It is possible that the piece is only a smaller specimen of C. praeamomum . 36
