Abstract
In this research, plant morphology and pollen micromorphology of 14 populations of 3 species belonging to two sections Plethiosphace and Hemisphace of Salvia genus in Iran were studied. In the morphological study 25 quantitative and qualitative characters were investigated and the results clearly separated the species into two groups. The pollen grains from the herbarium specimens were prepared by acetolysis method and then 4 quantitative characters were examined by light microscopy. Data was processed by principal component analysis method. Results indicated that although the pollen grains in the section were comparatively homogenous and all of them were 6-colpate with reticulate ornamentation, a considerable variation in the quantitative characters studied turned out to exist. However among the characters studied, equatorial and polar diameters of pollen grains were the most significant and based on these characters the members of these sections can be divided into two groups.
