Description of some genera and species of fossil pollen and spores

Abstract
In a former publication we gave a short description and provisional classification of number of species of Maestrichtian age (VAN DER HAMMEN, 1954). As we have established now more definitely the classification system, we give here now the complete description of some of these species and moreover of some new species from the Tertiary, as we need to mention those species in some publications on climatic changes which will soon appear. For the sa.me reason we describe some of the spore-genera we proposed in the former publication (VAN DER HAMMEN, 1956).
