  Pteridium aquilinum belongs to the family Dennstaedtiaceae and includes herbaceous, perennial and terrestrial plants with global distribution. This plant grows well in sultry and shady areas; Therefore, the northern regions of Iran are one of the suitable habitats for this species. In the present study, the anatomical structure of leaves in 15 specimens of this species was investigated by the double staining method. In total, 23 quantitative and 6 qualitative characters were evaluated and measured. Characters such as the presence of a uniseriate epiderm, the presence of collenchyma cells in the distance between the epiderm and the vascular bundle, the presence of a V-shaped vessel in the center of the vascular bundel, bilateral phloem, stomatal guard cells Renal shape and simple needle-shaped trichomes in the lower epiderm are prominent anatomical features of the leaves in this species. The results of statistical calculations such as WARD analysis, how the populations were grouped and also drawing PCA diagrams showed the diversity of characters in the populations. On the other hand, despite the consideration of lower taxa than the species in this plant in some studies, the results of statistical calculations based on the characteristics of the anatomical structure of the leaf in the present study ruled out the existence of these taxa.
