Pollen morphology of extant Winteraceae: a study allowing SEM-based affiliation of its fossil representatives

When applying high-resolution microscopy, the pollen morphology of extant taxa can be used to classify fossil pollen, that is, to address the latter in the established systematic-phylogenetic framework. Here we investigate tetrads and pollen features of 20 different Winteraceae species, most of them belonging to the early-diverging generic lineages Tasmannia , Drimys and Pseudowintera . The tetrads and pollen are grouped into eleven pollen types...
