Caucasia, W. Iran, N. Iraq. Ir.-Tur. element. This species appears to be identical in all respects except style number with C. szovitsii and will almost certainly prove to be conspecific. These two species together should perhaps be treated as a single ± stabilized species of hybrid origin, with C. orientalis and C. aronia as parents. If so, then the maintenance of a single species with a variable style number (2-4) would seem biologically reasonable, despite the fact that it would break down the distinction between the two traditional sections, Azaroli and Crataegus.
