ABSTRACT

Anatomical study has been done for the species Mentha longifolia, Micromeria myrtifolia, M.flacca. Thymbra spicata, T. sintensii, Thymus spp. and Ziziphora grown in Iraq.

Vertical section of  leaf  blade were of taxonomic importance, especially mesophyll and vascular bundle shapes which were used in grouping species of the above genera. Bifacial leaf found in Mentha longifolia, Micromeria spp. and Ziziphora sp., wherease unifacial was in Thymbra and Thymus species.

Shape of cross section of leaf midrib was variable in variable species and genera, therefore elleptic , semicirular, ovate-circular, remiform and curved shapes were determined. The vascular bundle was enclosed by one or more rows of a big parenchyma cells. These cells were spherical to oblong in shape as a bundle sheath . This was as a lacunar collenehyma above and below the vascular bundle in most species of the genera. Anyhow the vascular bundles of the species of Micromeria, Ziziphora studied were enclosed by fibers, especially in Z.tenuior.
