In this survey, anatomical characteristics of leaves in 35 populations belonging to 18 taxa of Scrophularia have been studied. Among 39 quantitative and qualitative anatomical characters, some have more suitable taxonomic value for differentiation of taxa, such as blade thickness, thickness of upper and lower cuticle of midrib, length of upper and lower palisade parenchyma of blade, thickness of lower epidermis wall of midrib, thickness of upper and lower epidermis of blade, rows of spongy parenchyma of blade, upper collenchyma type of midrib and the presence of idioblast. Finally, comparison of the results of the current study together with Grau’s (1981) results confirm the validity of 4 groups out of the 12 groups which he had introduced. As for the remaining groups, no noticeable concordance was found.
