Abstract
In this study, the pollen morphology and exine structure of nine species of the genus Salvia L. (Lamiaceae) were investigated using light microscopy and scanning electron microscopy (SEM). Six micromorphological characters (pollen shape, polar length, equatorial width, exine and intine thickness, colpus length and colpus width) of pollen grains of Salvia have been identified. The palynological observations revealed that pollen grains of most studied taxa of Salvia were suboblate shape and possess hekzacolpate aperture. Tectal surface sculpture was a good criterion to identify particular taxa from Salvia. The pollen of which is characterized by reticulate, the pollen ornamentation was similar in all studied taxa.

Highlights
The genus Salvia L., the largest genus in the family Lamiaceae, contains about 1000 species worldwide
For Scanning electron microscopy (SEM), pollen were removed by distilled water treatment, the air-dried, pollens were directly mounted on stubs using double-sided adhesive tape and uncoated
The pollen properties of nine species were studied by using LM and SEM (Fig. 1)
Summary
The genus Salvia L., the largest genus in the family Lamiaceae, contains about 1000 species worldwide. The authors have examined morphology, anatomy, trichome, nutlet, and pollen micromorphology of some Turkish Salvia species (Kahraman et al, 2009; Kahraman et al 2010). Aktaş et al, 2020 investigated some Turkish Salvia and they reported that palynological characters are important for differences among studied taxa. Salvia is spreading in the province of Mardin is one of the important genera represented by four sections and nine species.
