Some fragmented leaflets have turned up. They are asymmetrical and have petiole. Only one of them is measurable, its length is 3.7 cm, width is 1.3 cm. Shape is very narrow elliptic, apex is attenuate, base is presumably asymmetrical cuneate or dccurrent. Margin is toothed. The teeth are very small and much more sparse than that of the species of Pterocarya and Carya. The teeth are acute and charactcristical. Venation is hardly observable but it is likely to be semicraspedodromous. The midvein is thick and weakly curved. The angle of divergence of the secondaries arising from the lower part of the midvein is right and that of those that arise from the upper part is acute. The neighbouring secondaries anastomose at obtuse angle and form loops. Before the anastomosis a vein branches toward the margin and runs into a tooth. The tertiary venation is orthogonal reticulate. Material: No. 178, 201, 376c, 394, 483a, 536c. Pterocarya paradisiaca (UNGER 1849) ILJINSKAJA 1962 1959 Pterocarya denticulata (O. WEB.) HEER: ANDREÁNSZKY, p. 120, Tafel 32, Fig. 5, Tafel 33, Figs 2-3. The species is represented with a great number of leaves. They are symmetrical. Their petiole cannot be observed (presumably it has not remained). Lamina length 2.5-10 cm, width 1.2-3.9 cm. Shape elliptic, in some cases weakly obovate. Apex acute, base obtuse or weakly acute. Margin is toothed similarly to the species of Carya. The only difference between their teeth is the density of the teeth namely the teeth of Pterocarya paradisiaca is more dense than that of the species of Carya. The teeth are acute. Their apical side is acuminate, the basal is concave. The sinuses are angular. Venation is semicraspedodromous. The midvein is curved. The secondaries arise at angles of about 70°-80° and their course is curved. The neighbouring secondaries anastomose and form loops. Smaller veins branch from the secondaries toward the margin and run into the teeth. The tertiaries arise at right angle from both of the apical and basal sides of the secondaries and connect them. A vein is observable, arising from the apical initial part of the secondaries. Later it bends back to the midvein.

Carya minor SAPORTA et MARION 1876 1964 Carya minor SAPORTA et MARION: KOLAKOVSKU, p. 96, Tab. 8, Fig. 2. 1986 Carya minor SAPORTA et MARION: KNOBLOCH, p. 27, Taf. 14, Figs 1-4, Taf. 15, Figs 2, 3. We have only some leaflets among the remains. They are symmetrical and have petiole. Shape elliptic or obovate. Lamina length 0.7-6.2 cm, width 0.5-2.2 cm. Apex acute, base cuneate or weakly decurrent. Margin is toothed. The apical side of the teeth is acuminate, the basal is concave. The sinuses are angular. Venation is semicraspedodromous but the loops are not so expressed as it is in the case of Pterocarya paradisiaca. The course of the midvein is straight. The secondaries arise at angles of about 60°-70°. They are curved and do not reach the margin. M a t e r i a 1: No. 73, 80, 81, 147, 191, 197, 198a, 289b, 455a. Carya denticulata (WEBER 1852) ILJINSKAJA 1964 1964 Carya denticulata (WEB.) ILJINSKAJA: KOLAKOVSKU, p. 95, Tab. 36, Figs 3-6. Weakly asymmetrical leaflets, presumably they had petiole. Lamina length of the two leaflets is 2.2 cm and 4.1 cm, width is 1.2 cm and 1.3 cm. Shape lanceolate, apex attenuate, base obtuse. Margin is toothed like in the previous species of Carya, namely, the apical side of the teeth is acuminate and the basal is concave. Venation is semicraspedodromous and the loops are formed imperfectly. M a t c r i a 1: No. 186, 361. Carya sp. We have a great number of leaflets belonging to the genus of Carya. They are symmetrical and have petiole. Lamina length 3.2-9 cm, width 0.9-3.4 cm. Shape obovate, apex acute (but more weakly than that of Pterocarya paradisiaca), base obtuse. Teeth are similar to that of Pterocarya paradisiaca but they are bigger and more sparse. Venation is semicraspedodromous and the loops are formed imperfectly.
