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.
