Abstract
Fossil remains of Taxodium from upper Eocene to lower Miocene localities in Germany, the Czech Republic and Russia are investigated to reconsider taxonomic concepts. It is demonstrated that all material belongs to one species which is named Taxodium dubium (Sternberg) Heer emend.
Using the whole-plant concept, T. dubium is considered as a synthetic species comprising foliage, seed cones, seeds, and male cones with pollen in situ. Shared identity of T. dubium and the wood morpho-taxon Taxodioxylon taxodii Gothan is assumed.
