Abstract
The current research was conducted anatomical study of the transverse section of stems, petioles and leaves Melilotus Mill. and Scorpiurus L. genera (Leguminosae) in Iraq, which included four species (M. alba, M. indica, M. messanensis and M. officinalis) of the first genus and one species is two variety (S. muricatus var. muricatus and S. muricatus var. subvillosus) to second genus. Studied the anatomical characteristics of the stem and shape of transverse section unrealized lead in anatomical study from the rest of the other parts also studied the anatomical characteristics of petiole was shaped of transvers section taxonomic importance possible through the division of species on four groups according to the what helped to diagnose and isolate gender species. Transverse sections for the blades leaves showed taxonomic importance in terms of the thickness of the blade and the number of rows of the vascular bundle of moderation and the number of packets in each row and thick possible way for the diagnosis of gender species when the leaf characteristics showed the importance of the genera separation as well as species separation and had a number of palisade tissue layers importance in the separation of the species into two groups and the number of vascular bundles and form important in the genera separating from each other.
