Description: The leaves are large, long, one of them is 13.6 cm while the other one cannot be exactly measured due to the lack of the basal parts, but its total length probably reached as much as 17-18 cm. The width of the leaves is only 2.6 and 3.4 cm, respectively. Their form is elongated, the margin of the leaves is entire. The midvein is very strong, mainly at the basal parts, but also at the medial parts as well. The angle of divergence of the secondary veins on the species 76.147.1. is somewhat steeper than on the other. Here we are facing an angle of divergence well under 60 , while in case of the specimen 76.190.1. the same angle is about 63-69 . The camptodromous venation is not striking, we can observe loops only in case of some secondary veins. The secondary veins branching of the midvein follow each other at relatively regular intervals. Laurophyllum sp. IV. Pl. XXIV, Fig. 1; Pl. XXV, Fig. 1; Figs. 48-52. Material: No.: 76.1.190.1.; 76.200.1.(2). 3 pieces Description: The form of the leaves is elongated ovate. Their length is 9-12 cm, their width ranging about 3-5 cm. The basis is acute, fragmented at all the three specimens. The apex is missing. The margin of the leaves is entire. The venation system seems to be, at a quick glance, craspedodromous

, because the veins are strong enough only at the straight phase. In fact, the leaf is camptodromous. A characteristic feature of the species, however, that the loop-like connection of the secondary veins are very thin, poorly visible to the naked eye. Over the loop-like connection of the secondary veins there are further loop systems formed at a longer phase. The number of loops can reach 6-7 at the medial phase of the leaf. The secondary veins are very regular, running parallel to each other at no great distances. They are rigid and form no arched curvature opposed to most of the leaves with a camptodromous venation. (Fig. 49). The entire margin and the character of the venation denotes the family of Lauraceae. Unfortunately, the rigid secondary vein system does not allow us to identify our specimens with any of the known species of this taxon. Lacking the epidermis it would be hazardous to bring it into close connection with any species. Laurophyllum cf. acutimontanum Mai Pl. XII, Fig. 4. 1950 Laurophyllum phoeboides (Ett.)

Description: The most complete specimen is a 12.8 cm long, 1.9 cm wide leaf. Its form is lorate. The apex and the basis are equally acute. The basis is a little bit fragmented, but seemingly symmetrical. The margin of the leaf is entire. The midvein is well observable, while among the secondary veins, only a few are visible, and even they cannot be observed at full length. The entire margin, acute apex and the character of the secondary veins denote the above mentioned genus. Having no remains of the epidermis, the precise assignment of the piece is uncertain. 14
