  S. Bulgaria, S.W. and C. Asia. Ir.-Tur. element. Closely allied to A. micrantha Willd. from the S. parts of USSR. Material of A. biebersteinii is often found in herbaria named as 'A. micrantha Bieb.' (Fl. Taur.-Cauc. 2:336, 1808), although the authority for the latter name should have been attributed to Willdenow (1803).
