Abstract

Fossil collections made from the Middle Miocene at Magyaregregy have yielded several impressions of fruits and asymmetrical leaves with toothed or rarely entire margins that belong to the genus Ailanthus. A detailed study of size ranges and morphology suggests that fossil fruits from Magyaregregy are identical to a single fruit known from Erdo′bénye and also with the type specimens of A. confucii Unger, but differ from those recorded from the Tard Clay Formation. Since fruits and leaflets occurring at Magyaregregy are not attached, the latter are described as Ailanthus mecsekensis sp. nov. Fruits from the Tard Clay Formation differ by size ranges and morphological details from other fossil species of Ailanthus and are described as a new species, Ailanthus tardensis sp. nov.
