In this survey, 9 Iranian taxa of Anemone L. and Pulsatilla Mill. are studied by their leaf macro and micro-morphological features to understand the importance of these characteristics in identifying taxa of these genera. In order to achieve more accurate results the scanning electronic microscope (SEM) is also used. Several features such as size, shape, trichome, epidermal pattern, segment shape and tip of leaf are tested. 4 types including Trisect, Palmately trisect, Ternately compound and Pinnaitesec are observed based on leaf shape and 4 types which are reticulate, rugos, striate and simple are identified based on epidermal pattern. Using Principal Component Analysis, it is observed that features such as length, shape, epidermal pattern and segment shape of leaf demonstrate the most distinctive characteristics and they are capable of separating the species and even the varieties. Furthermore, the separation of the taxa is well observed in phenogram.
