Hably, L.: New data to the Eocene flora of Hungary

appear in the warmer periods of the Miocene, but to the presence of the Arctotertiary elements which entered at the end of the Paleogene and competetively displaced it from the Central European flora. The presence of Nyssa is indicative of its habitat, since most species of this genus live in wetlands. The Eocene transgession was a gradual process in Transdanubia, therefore the formation of marshland and coal was possible. Nyssa is a member of a marshland habitat. It occurs only in small numbers in the fossil flora hence it cannot be regarded a predominant or characteristic species. To summarize, it may be said that the flora of Tatabánya-Márgabánya lived in a tropical climate in the Eocene. A distinction of habitats based on these few species is not possible but the presence of Nyssa is indicative of a marshland. The plant communities are yet to be demarcated. Only after the identification of the complete flora can we say anything closer about it. References ANDREÁNSZKY, G., (1951): Adatok a hazai harmadkori flóra ismeretéhez.
