Material: sample No 713, depth 1538.0 m, No 713, depth 1540 m A trilobate leaf. The lobes meet at an acute angle. They become divergent only in their upper third. The central lobe is the longest one, the two side lobes are somewhat smaller. The veins running to the lobes are arched, not rigid. Large, irregular teeth are visible at the margin of the leaf. Rare specimens of the species are recovered from the Pliocene of Poland and the Upper Miocene of Greece. Typhaceae Typha L. Typha sp. A member of plant communities living in swamps, determined by edaphic factors. Cyperaceae Phragmites L. Phragmites sp. Material: sample No 713, depth 1538.0 m For remarks, see under Iharosberény-I. Monocotyledoneae Material: sample No 674, depth 1460.9 m, No 695, depth 1487.2-1487.0 m, No 713, depth 1539.0 m, No 713, depth 1540.0 m Nympheaceae Pl. VII, Fig. 2. Material: sample No 674, depth 1460 m The diameter of the rhizoma is 1.5 cm; the surrounding fringes can reach 3 cm, while their width is ranging between 1.5-2.0 mm. FLORISTICAL EVALUATION The plant species recovered from the Tiszapalkonya-I. borehole belong to the phyla gymnospermatophytes and angiospermatophytes. The phylum Gymnospermatophytes is represented by one species of a single genus, i.e. Gfyptostrobus europaeus. Both classes of Angiospermatophytes (Monocotyledonopsida and Dicotylodonopsida) are present in the flora, the latter comprises the bulk of the material. They are represented by 8 species of 7 genera, while only two genera of the monocotyledons were found. Dominant elements of the flora are Gfypto-
