| Summary: | Principal pollen characters, of the Cape floristic Regions ten richest families, which are phylogenetically useful at higher taxonomic levels (including aperture type, exine structure, pollen-unit, polarity, symmetry, shape), and their evolutionary trends are examined. Monocotyledons differ from eu-dicotyledons (and eu-dicots from basal-dicots) in their aperture number and form, and exine structure and are discussed in relation to their pollination syndrome aswell as their evolutionary trends. We also discuss the possibilities of creating a taxonomic key at species level, if not only for use at the vegetation-type scale for paleobotanists aswell as honey farmers.
