الملخص الانجليزي
The current study aims to study the anatomical characteristic of epidermal cells, indumentum and cross sections of
stems, leaves, petioles, fruitsand seedsof Corchorusolitoriusfrom Malvaceae family, which collected from the herbal
garden of AL-Rashidia city north of Baghdad. The anatomical study showed important characteristics can assessing to
recognition the morphological characteristics which can be used to cultivated and increase the Corchorusolitoriuscrop
in Iraq because of its high medical and nutritional importance of this species. The most important characteristics
identified during the process of studying cross sections of plant parts are the stem is circular shape consists from
uniseriate epidermis covered by cuticle and the cortex in addition the vascular bundles consist of xylem and phloem,
As for the leaf epidermis appear stomata anisocyticshape and many glandular trichomes diffuse in the surface of
epidermis, the head of this trichomes consist from multicellular cells,this is an important taxonomic characteristic for
distinguishing between species within one genus and the upper epidermisconsist from large vacuole alsothe mesophyll
showed numerous prismatic crystals diffuse in the cells, the midrib of leaf showed that the shape of the whole section
like flask shape and from the upper side the upper epidermis and part of cortex constitute special shape like as the
camel hump and under it located big cavity or known specialized schizogenous intercellular spacesalso this characters
considered special taxonomic feature to distinguished between the species,the vascular bundle central located under
the cavitycrescent shape include xylem and phloem.The cross sections of petiole horseshoeand many unicellular and
uniseriatetrichomes spreader on the epidermis of it.
