Abstract :

This study provides the possibility of investigating the natural classifications of Alopecurus species based on leaf anatomical features. In Iran, the taxonomy of this genus is very small and the anatomical structure of the leaf has not been used in its taxonomy. The samples of 7 identified species were examined in terms of shape and differential shape characteristics were determined. Also, the samples were examined in terms of the anatomical structure of the leaf in transverse section and epidermis, and the anatomical characteristics of the leaf were determined. Differential anatomical features were distinguished. 38 morphological traits and 18 anatomical traits were investigated as differentiating traits between species in terms of numerical taxonomy separately and in total 56 traits. The results of this research confirmed the natural classifications.
