Chorology and Phytogeography of Mil steppe and environs were studied. The results show that; 926 species belonging to 457 genera and 91 families were recorded. Five families: Poaceae, Asteraceae, Fabaceae, Brassicaceae and Chenopodiaceae contribute 42.51 % of the total plant species recorded in this study. Poaceae is represented by 59 genera (12.83 %) of the total observed plant species. Asteraceae carry 54 genera (11.83 %), while Brassicaceae, Fabaceae and Chenopodiaceae carry 39, 22 and 21 genera (8.48 %, 4.79 %, and 4.57 %) respectively. 40 endemic species belonging to
31 genera and 20 families were listed. Among them, 25 species are endemic to Caucasus, 11 species are endemic to Azerbaijan and 4 species are subendemics. The majority of the listed species in this study are annual represented by 440 species (47 %), the second most recorded life span was the perennial, which are represented by 404 species (44 %). Five life forms are observed in the current study. Therophytes are the most frequent life form with 475 species (51%), followed
by hemicryptophytes with 314 species (34 %), Cryptophytes with 76 species (8 %), Phanerophytes with 26 species (4 %) and Chamephytes with 38 species (3 %). Chorological analysis revealed that the Mediterranean -Irano-Turanian is the most dominant phytochorion represented by 151 species (13.1 %), followed by Palearctic and Mediterranean phytochoria represented by 115 species (12.5 %) and 113 species (12.3 %) respectively.
