| Abstract | ||
| The research included anatomical study of nine wild species of the genus Athionema R.BR. from BrassicaceA family in Iraq, and these species are: A.arabicum (L.), A.carneum (Banks et sol.),A. cordifolium (DC.), A.fimbriatum (Boiss.),A. froedinii (Rech. F.), A. speciosum (Boiss. et Huet), A. syriacum (Boiss.),A. grandiflorum (Boiss. et Hoh.) , A.trinervium (D.C.).The research covered the anatomical characteristic of the leaf Epidermis as well as leaves venation, also transvers sections for leaves were studied ,and revealed that some anatomical characteristics have taxonomic importance in distinguishing the species. This research also showed the presence of important variations in internal charecters for leaves anatomy as it was characterized as Bifacial and variation between the Palisade layer and spongy layer in term of their cell thickness ,as some species were distinguish by interfering of palisade and spongy layer .The study also showed differences in stomatal complexes pattern , and the characteristics that related to the shapes of the Epidermal cells of leaf and leaf venaition have also important taxonomic and diagnostic value in the species under study | ||
