The pollen morphology of 14 species of Acanthaceae (8) and Verbenaceae (6) usually cultivated in southern Europe, has been studied by light and scanning electron microscopy. Pollen was acetoysed by the method of Erdtman (1960) modificated by Reitsma (1969) and mounted in glycerine jelly for light microscopy. For scanning electron microscopy the pollen were coated of gold evaporate.
The taxa examined of Verbenaceae has 3-colporate or 3-colpate pollen grains with psilate-perforate or perforate-reticulate surface. Instead, Acanthaceae present trizonocolpate, trizonocolporate, heterocolpate, bizonocolporate and spiraperturate pollen types with various ornamentation.
