A detailed palynological study on some taxa of the Alcea L. and Althaea L.genera in Turkey.

Pollen grains of 10 taxa from Alcea L. and Althaea L. genera (Malvaceae) were examined with LM (Light Microscope) and SEM (Scanning Electron Microscope) to assess whether pollen traits can be used to delimitate at generic and specific levels. The results of the study showed that 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 pollens than pollens of Alcea. The results of this study confirmed that whereas differences about pollen characteristics among the taxa are not functional in separating taxa at specific level especially in Alcea genus, there have been strict differences based on pollen morphology between two closely related genera.
