Öz In this study, the pollen morphology of pollen grains taken from herbarium specîmens of 32 taxa of the genus Teucrium L. (Labiatae) have been investigated with a light microscope. The pollen grains show stenopalynous features. Pollen grains radially symmetrical, iso- polar, prolate, prolate-spheroidal, subprolate, 3-colpate, operculicolpate, amb intersemiangular. Exine sculpture distinctly verrucate, ohscureîy verrucate, granulate, ohscurely granulate. Exine thicker at poles, sexine much thicker than nexine. Operculum surface covered with small processes. According to palynological characteristics, the taxa of the genus Teucrium examined have been divided into four groups. Some taxonomic problems are attempted tc be solved by means of palynological data.
