Dieter is grown in Iraq as an ornamental plant. In this research, the anatomical characteristics of different parts of Caesalpinia gilliesii were studied in detail. The study included the characteristics of the epidermal cells, such as the tangential walls and the distribution of stomatal complexes of the leaflet and stem. The ornamentation of the epidermis, as well as the internal structure of stem, pulvinus, petiole, leaflet, and fruit, were also described. Different types of glandular and glandular hairs and crystals in different parts of the plant were also described.
