Artemisia melanolepis Boiss. and A. aucheri Boiss are two dominant species on southeastern of Sabalan. As a part of main project of identification of Artemisia habitats in Ardabil province, this study is to study the flora on their habitat selected. The aim of this study was to investigate the flora, life form, geographical distribution, diversity and evenness of accompanying species of A. melanolepis and A. aucheri in the southeastern of Sabalan. Species were collected from among two habitats and 84 identified species which belonged to 23 families and 61 genera. Asteraceae, Fabaceae, Lamiaceae and Poaceae families were the dominant ones. Astragalus and Poa were the dominant genera in the studied habitats. According to the Rankaier's system, the identified species in the study area included 68% hemicryptophytes, 11% therophytes, 15% chamaephytes and 6% geophytes, respectively. In the habitats of A. aucheri and A. melanolepis, hemicryptophytes with the highest frequency is the dominant one with 69% and 77% of accompanying species, respectively. In the habitats of A.aucheri, chamaephytes species with 18.4% is the second dominant life forms. The second life form of the accompanying species of A. melanolepis, with 13.5% is the therophytes. Geographical distribution of plant species in the study area indicates that the Iran-Turanian region with 56.09% has the highest frequency. In the habitats of A.aucheri and A. melanolepis, species with geographical distribution of Iran-Turanian region with 24 and 16 species are the dominant ones, respectively. Results of the numerical diversity indices (Simpson and Shannon-Wiener) and evenness (Simpson and Smith-Wilson) habitats shows that Simpson index have no significant differences in the accompanying species of two Artemisia species but the Shannon-Wiener diversity index in different elevation and aspects have a significant difference. The results of this study, besides the basic information and understanding of A.aucheri and A.melanolepis habitats, and also the identified species in this study can be used in the restoration and reclamation of the habitats of these species.
