Pollen grains of 22 taxa from Alcea L. and Althaea L. genera (Malvaceae) were examined using light microscope and scanning electron microscope to assess whether pollen traits can be used to delimitate at generic and specific levels. Furthermore quantitative data were subjected to cluster analysis. The pollen grains of Althaea genus are spheroidal, pantoporate, echinate which is characterized by having subglobose pattern at the base of echinae. The pollen of Alcea are spheroidal, pantoporate, echinate and baculate. Distances between pori are longer in Althaea (9.04–12.75 μm) pollens than pollens of Alcea (5.12–7.28 μm). The results of this study confirmed that differences about pollen characteristics among the taxa are not functional in separating taxa at specific level especially in Alcea genus, whereas there have been clear differences based on pollen morphology between two closely related genera.
