The taxonomic status of Scorzonera pygmaea var. pygmaea and var. nutans belonging to the tribe. cichoreae (Asteraceae). S. pygmaea samples were collected from Arayit mountain. We suggest that these two subspecies should be classified as varietes because of their morphological and anatomical characteristics, ecological and geographical similarities. Moreover being together in the same localities of these under species taxa supports our opinion, i.e. S. pygmaea Sibth. & Sm. var. pygmaea stat. nov. and S. pygmaea Sibth. & Sm. var. nutans (Czeczott) O. Koyuncu & Yaylaci{dotless}, stat. nov.
