Artemisia (Asteraceae) have 34 species and the most vast distribution after Astragalus in Iran. It has very useful values from several viewpoints (such as pharmacology, forage, soil conservation, botany, ecology and etc). Artemisia species have special anatomical characteristics that are effective in extensive dispersion and adaptation to extreme environments.In this research, anatomical characteristics of five Artemisia species (A.absinthium L., A. annua L., A. scoparia Waldst. and Kit., A. spicigera C. Koch, A. vulgaris L.) in the north of Iran were studied. The specimens collected from various habitats were fixed in FAA solution. Transvers sections studied and measured in laboratory by microscope. According to PCA analysis on gived data, A. annua and A. scoparia distinguished from other species because of shizogenous channels, number of palisade parenchyma layers and stoma frequency in upper layer of leaf. A. vulgaris and A.absinthium separated from others by diameter of stem, number of vascular bands and parenchyma layers in stem cortex. Also, with respect to cluster dendrogram, A. annua and A. spicigera have isobilateral leaf, so situated in one cluster. They are rather similar in stem diameter, number of stem cortex parenchyma layers and vascular bands with A. scoparia. They placed in higher cluster together. A. vulgaris and A.absinthium situated in another cluster.
