Abstract

The current investigation concluded an anatomical study of the cultivated species Pelargonium graveolens L. 'Hér belong to the Geraniaceae family and which cultivated as an ornamental plant, fresh specimen were collected from different region in Baghdad ,the study vegetative parts (leaf, stem and petiole) in details ,the upper and lower epidermis of leaf and epidermis of stem also studied, ordinary epidermal cells and stomatal complexes studied in term of shapes and dimensions ,the result showed that stomatal in leaf and stem is anomocytic type, the cross sections of the vegetative parts prepared by microtome and free hand sectioning. The tissues of these parts include the number and the type of layers and thickness of each one , the result showed the presence of druses crystals in parenchyma cells of the petiole, stem and leaf. Vistur type of this organs also studied and it comprises of glandular and non-glandular trichomes which occur in different types and lengths.
