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.

The present survey has been carried out on sixteen species of the genus Linum L. in Iran with the aim to illustrate inter specific relationships and to evaluate the taxonomic treatments proposed for the genus on the basis of morphological and palynological studies and further application of multivariate analysis to the data resulted from these studies. Grouping of species has highly supported the proposed memberships of Linum species in Iran and application of palynological data together with morphological data has been proven to be efficient for application at sub-generic level in taxonomic treatments of the genus Linum in Iran.

The genus Chenopodium L. is belongs to chenopodiaceae family with 15 species occur Iran and it is one of the complex genus in this family. The main purpose of these studies anatomically characters analyzing among the members of this genus and evaluating the efficiency of these features in systematics of the genus. Various anatomical characters such as ; shape of stem, presence of trichum and its variation, cortical parenchyma and sub- epidermal collenchyma, vascular bundles were very different between species. Species and sub species were easily separated from each other by mean of anatomical characters.
