Cornus species are not known from the Lower Oligocène of Hungary as yet. According to recent evidence, their first appearance can be dated to the Upper Oligocène. From this period on, there are several occurrences of the genus known from the Miocene. Nowhere in Hungary was it found dominant. The genus could possibly arrive to Hungary as a member of the Arctotertiary wave. Numerous representatives of Cornus used to live, during the Miocene, in the neighbouring Czechoslovakian territories. The genus is mainly known from the Miocene at other regions of Europe and Asia as well. Probably, the genus occupied a similar place in the vegetation ever since the Egerian and the Miocene. It is recently known from the bush level of the sunny hill-side forests. On the basis of its quantity, we can suppose similar role within the vegetation since the Egerian. Smilacaceae Smilax L. Smilax tataensis Hably et Csaba Pl. XXXV, Fig. 1; Pl. XXXVI, Fig. 1; Pl. XXXVII, Fig. 1; Pl. XXXVIII, Fig. 1; Figs. 128-133. 1977 Smilax tataensis Hably et Csaba; Hably et Csaba, p. 23, Text-figs. 1-8. Material: No.: 76.180.1.; 76.189.1.; 76.229.1.; 76.230.1.; 76.231.1.; 76.232.1.; 76.252.1.; cf. 76.177.1. 8 pieces Description: in HABLY et CSABA (1977). The leaves are essentially different from those of S. weberi

, as well as 5. grandifolia generally considered as synonim of 5. weberi

. One of its most distinctive features, observable on one of the leafprints published by BÖÍEK (1971 p. 90, Text-fig. 4.) that the basis is short, in spite of the widening of the lower parts of the leaf, terminating in an acute peak, i.e., decur:ent. On the specimens of 5. tataensis the starting point of the vein system - that is, the contact of the shaft and the lamina - is placed well over the end of the shoulders of the lamina. Typical of the 5. tataensis

, is the regular vein system between the primary veins Nr. 1 and 2 from the midvein, consisting of acutely terminating loops

. 5. tataensis is nearest to the form mentioned under the name of 5. gran difolia at HEER (1855) Pl. 30, Fig. 8, STAUB (1887) Pl. 20-21, Figs. 1-7; Pl. 22-23 , Figs. 1-5; Pl. 24, Fig. 1. This species in out opinion is not the same as S. weberi

. Accordingly, the specimens published under the name of 5. weberi and S. grandifolia cannot be lumped together under the name of one species. STAUB (lBB7) mentioned and demonstrated several Smilax species from the Upper Oligocène flora of the Zsil valley. These specimens are probably the nearest kins of 5. tataensis

, on the basis of their form and vein system. For example, on one specimen of the Zsil valley (STAUB 1887, Pl. 22, Fig. 2) we can find the loop-form vein system near the margin while, however, on the Zsil valley specimens the connecting veins are almost horizontal (branching out at an angle of 90 ) and they are fairly densely placed, in case of S

. tataensis, the angle of divergence is steep (enclosing 35 - 45 with the horizontal direction) and they are fairly far from each other. Concluding from the large leaves of the 5. tataensis as well as the recent representatives of the genus we can say that most likely it was a creeper plant of the subtropical, humid vegetation.
