Description: 5.6 - 9.5 cm long, 1.8 - 4.4 cm wide, simple leaves. Shape of the lamina is very narrow elliptic or lanceolate, apex and base acute, base mostly asymmetric,. Margin entire in the basal part, and toothed in the upper two-third of the lamina. Teeth small, simple, tooth-apex obtuse, sinuses rounded, making S-form. Midvein strong, venation camptodromous, secondary veins are thin. Between the secondary veins intersecondaries are running out of the midvein. Discussion: Platanus neptuni is one of the most dominant element in the Egerian floras ofHungary. In Pomáz it is not so frequent, as in some other Egerian floras, e.g. Vértesszőlős (Hably 1990). The species appeared in Hungary in the Early Oligocène, and peristed to the Early Miocene. In the Ottnangian flora of Ipolytamóc it is still a dominant element of the flora. Platanus neptuni is a thermophilous, paleotropical element of the mesophytic forest.
