| Abstract | ||
| The present investigation comprises comparative anatomical study for 6 species belong to 6 genera (Ammochloa palastena Boiss. , Arrhenatherum kotschyi Boiss., Diagn. ser, Crypsis aculeata (L.) Ait. , Cynodon dactylon(L), Chrysopogon gryllus L. Trin, Oryza sativa Pl. L., Sp.) belong to 4 subfamilies: (Pooideae,Chloridoideae ,Panicoideae, Ehrhartoideae) from family Gramineae in Iraq, Anatomical study comprises investigation of epidermis and Transverse sections characters for stem, It showing the epidermis contain (long cells, short cells, stomata, microhairs, prickle) the quanitative and qualitative characters of these structures were found to have important role in identification and isolation at species and subfamilies level especially shapes and numbers of short cell and stomata, and shapes of microhairs, Transverse sections contained Parenchymatous, Sclerenchymatous and vascular bundles, the Sclerenchymatous mostly made girders connected between vascular bundles, the diameters, and shape of these tissue varied among different species level studied, outline shapes and states (Hollow or Solid) of sections, present or absent Kranz cell, have taxonamic important in isolation. | ||
