Calamitean Cones and Their In Situ Spores from the Pennsylvanian Limnic Basins of the Czech Republic

-Stephanian). The in situ spores were compared to twenty dispersed species of Calamospora. The majority of spores were microspores, however, some cones yielded both micro- and megaspores. Morphological variations o...
