Monocotyledonae sp. 1 Material; 86.227.2., 86.402.1., 86.403.1., 86.432.1., 86.436.1., 86.437.1., 86.438.1., 86.439.1., 86.534.1., 86.663.2., 86.679.2., 86.681.1. Description: 0.6-1.4 cin wide leaf fragments with parallelodromous venation. Discussion: These monocotyledonous leaves have no characteristic remarks for the determination of genus and species. Monocotyledonae sp. 2 Material; 86.446.2. Description: 2.4 cm wide monocotyledonous leaf with a nodus and parallelodromous venation. The distance between the veins 0.2-0.3 cm. Between the veins dense oblique venation is visible. Discussion: The specimen is different from the above mentioned monocotyledonous leaves, but we cannot say any closer about its taxonomic position. COMPOSITION OF THE FLORA The Pomáz flora is one of the richest floras of Egerian age in Hungary. 0.1.2% of the specimens are ferns (Pronephrium stiriacum), 1.45% are gymnosperms (Taxodiaceae), while 98.43% belong to the angiosperms. As to the latter group, the family Lauraceae, represented by Daphnogene and Laurophyllum species, makes up 26.63% of the whole flora. Juglandaceae is the second most common family (21.20%) with the genus Palaeocarya: Palaeocarya orsbergensis, and a single specimen of Palaeocarya macroptera. The family Ulmaceae, represented by only one species, Ulmus pyramidalis, gives 19.63% of the whole material. Beside these prevailing forms, the family Leguminosae is also important (7.7%), and displays conspicuous diversity. Presence of Acacia parschlugiana, Cassia sp., "Colutea" kvaceki, "Dalbergia" bella, Leguminocarpon div. sp, and Leguminosae div. sp. indicates that this group enjoyed rather optimal conditions in the Late Oligocène. The family Platanaceae is represented by two related Palaeotropical species, Platanus neptuni and P. fraxinifolia. It is noteworthy that, in contrast to other localities, P. fraxinifolia is more common here than P. neptuni. The family Fagaceae (6%) is represented by the genus Quercus, especially Q. apocynophyllum. Beside the 1.56% ratio of the monocots, it is conspicuous that a single species, "Rhamnus" warthae makes up 1.2% of the total specimens. (The Pomáz palaeobotanical site is the second richest source of this species after the Wind-brickyard, Eger.) The individual character of the Pomáz flora is contributed by the occurrence of several rare elements, such as Dicotylophyllum jungii, Magnolia mirabilis, "Myrica" hakeaefolia, Daphne oeningensis, D. aquitanica, Wisteria aff. fallax, Theaceae, Rosa lignitum, Dicotylophyllum div. sp.
