This study included small part of the anatomical characteristics of the peduncles, which included the characteristics and dimensions of the epidermis, cortex, vascular cylinder and its components, medullary rays, pith through the cross sections of peduncles belonging to 12 wild species belonging to 11 genera were collected during 2013, 2014 and 2018, and diagnosed in herbarium of University of Anbar. These sections gave a clear and new anatomical imprint for each species added to the previous morphological and genetic imprints to be used in isolating plant species categorically, microscopic sections were filmed with a tabulated selection of anatomical measurements.
