Abstract: This study aimed to compare the palynological features of some species: <i>Iberis sempervirens</i> L., Bunias erucago L. (Brassicaceae family), and <i>Aster tripolioum</i> L., subspecies pannonicus (Jack.) Boo. (Asteraceae family). The botanist Ermelinda Gjeta determined these species. I have prepared five slides for each species using acetolysis and the basic fuchsine method. The study of these species' palynological features was done for the first time in Albania. We have compared the features with those of <i>Bunias orientalis</i> L. and <i>Aster albanicus</i> Degen, taken from local and foreign literature. According to the results of this study, the pollen grains of I. <i>sempervirens</i> and B. <i>erucago</i> were tricolpate inaperturate; in the equatorial view, the shape of pollen grains was elliptic to circular, while in the polar view, the shape was circular. The pollen grains of A. <i>tripolioum</i> L., subspecies <i>pannonicus</i> (Jack.) Boo. were tricolporate; in equatorial view, the shape was spheroidal. The exine has an echinate sculpture and was bilayered in A. <i>tripolioum</i> L., subspecies <i>pannonicus</i> (Jack.) Boo., while in I. <i>sempervirens</i> and B. <i>erucago</i>, the exine was reticulate.
