Globally, the number of species of this genus has been more than 500 species. A number of 34 of these species have been reported in Iran, with 8 species in Isfahan province. The wide distribution of Artemisia species in Iran makes this genus one of the main elements of the Irano-Turanian region. In order to morphologically investigate the genus Artemisia, the quantitative and qualitative characters related to reproductive and vegetative structures of this plant were collected in 64 samples. The researchers obtained the cluster diagrams and principal component analysis (PCoA) for the morphological characters of the specimens by using GenAlEx 6.5 and NTsys 2.02 software. In the cluster diagram, the Seriphidium Besser ex Less. Dracunculus Besser Rydb. and Artemisia subgenera were placed in separate clusters and next to each other. The results of the present study showed that some traits such as gender and situation of flowers in the capitulum, indumentum of the stem and receptacle, the situation of petiole at the basal and middle leaves, trichrome on both sides of the leaf surface, and the shape of outer phyllaries and their indumentum had more taxonomic value. Finally, the paper presents an identification key for the Artemisia species in Isfahan province, Iran.
