researching about  Islamic Iranian Botanical literature shows that iranian botanists Have presented a detailed morphological description of the different plant organs. They have a lot of descriptive measures that are compatible with modern science.So reviewing and classification This disorganize d and scattered information in the literature is useful for  the sciences that  related to modern botany and will acquaintance with the achievements, methods and knowledge on Islamic civilization and invaluable heritage.Materials and Methods: This study ranged from third to seventh century AH and the area IS where the Iranian cultural.
The research method is descriptive– analytical. FIRST Have been identified the scientists who studied IN his works aspect of the morphology of the leaf tissues AND THEN Information analysis and classification is based on today's knowledge. Based on information obtained during THIS period is divided TO three BRANCH: formation Efflorescence and Stagnation. Discussion and conclusions SCIENCE of limb morphology of leaves in the third century Is formed  AFTER Compilation THE BOOK AL-NABAT  AND Descriptive criteria DinawarI  is evident in the book Alhavy.  TGIS SCIENCE  HAS REACHED ITS PEAK in the indicator works such as Avicenna QANON and al-seydaneh  BIRUNI But then just repeat information and purifying botanical descriptions of the ancestors. Taken together the data analysis can be found in the literature in terms of size, scale leaves divided to: Broad, narrow, elongated, small and large, In terms of the lamina, leaves have circle, shield, needle, rectangles, triangles and compound ternate. Leaf margins are also divided into the a variety of Like Saw, slim, congregations, sharp, split (cilantro). Leaf surface also divided to  forms a coarse, smooth, soft, sticky, fluffy (Mozaghab), Downy, Fat (Dasam), Thorny and Striated. The leaves also have a variety of colors green, red, yellow, khaki, black and white. Back and front  some of the leaves are also two different colors. Placement arrangement of leaves on the stem are als divided to o frequently cross-dispersed, laid on the ground, close to the ground, clinging to shoot, shoot tip and are far apart.
