Abstract:
A total number of 11 Plantaginacean species were investigated palynologically by LM and SEM, 5 different pollen types have been recognized and the keys for these observations were prepared. All specimens investigated have polypantoporate type with many pores in ecto-and endo-aperture, but with more or less or even no annuli and costae.
