Pollen morphology of the some taxa belonging to genus the Alyssum L. distributed in Turkey

In this research, the genera Alyssum L. A. linifolium Stephan ex. Willd. var. teheranicum Bornm., A. simplex (L.) Rothm., A. trichocarpum T.R. Dudley & Hub.-Mor., A. armenum Boiss., A. praecox Boiss. & Bal., A. lepidoto-stellatum (Hausskn. & Bornm.) T.R. Dudley, A. sulphureum T.R. Dudley & Hub.-Mor., A. murale Waldst. & Kit., subsp. murale, A. pateri Nyar. subsp. pateri of the family Brassicaceae, have been studied in terms of palynological properties. The specimens of these taxa were collected during the field surveys were investigated using Light Microscope (LM) and Scanning Electron Microscope (SEM). As a result of this study some common traits of the taxa found out such as polen tectate, the pollen shapes being subprolate, prolate and the symmetry being heteropolar. the type of the aperture is tricolpate. The SEM microphotographs shows that the ornamentations are reticulate.
