Rhamnus L. is the genus of Rhamnaceae in Iran with nearly eight species. These species are used as valuable shrubs. This research was carried out in order to investigate the anatomical leaf. Samples from nine populations of Rhamnus pallasii and Rhamnus cathartica were taken. Treatment specimen cover various habitats from north of Iran, moreover herbarium samples were taken into account. The results presented two forms of epidermal cells such as Polygonal and irregular cells in addition, waved and straight anti-clinical walls were observed in R. pallasii subsp. pallasii and R. pallasii subsp. sintensii. Two types of stomata were demonstrated like anemositic and parasitic in two main species. Some characters e.g. thrichome, parenchyma, collenchyma layers were determined to finding some similarity among treatment specimen.
