Abstract
This research included the anatomical features study that included thirty-two wild plant species belonging to six genera of the subfamily Papilionaceae growing in central and northern Iraq districts. The genera Astragalus, Lathyrus, Medicago, Pisum, Trifolium and Vicia. The samples were collected from 2022 to 2023. Approximately thirty-four field tours were carried out, including central and north Iraq regions, and a comprehensive survey of preserved herbarium specimen samples in the National Herbarium of Iraq and other university Herbariums for diagnosis. Then the leaves were examined. The results showed that the ordinary epidermal cells showed significant and prominent variations on the upper and lower surfaces, as they could be divided into three shapes, including strongly undulated, little sinuate, and straight-curved ordinary epidermal cells. In the dimensions, it was found that the lower epidermal cells are larger compared to the size of the upper epidermal cells and that the number of stomata on the upper epidermal surface is greater than the lower epidermal surface. Moreover, the stomatal index on both surfaces showed significant differences, with the highest stomatal index recorded on the lower surface of the epidermis, compared with the upper surface gave the least. However, the shape of the guard cells on the two surfaces ranged between widely reniform and elongated reniform. Therefore, these dissimilar characteristics promote the separation and isolation of the studied species.
