Endemic, lr.-Tur. element. Closely related to O. elwendicum Wettst.; treated as conspecific in Flora Iranica - Boraginaceae 196 (1967). After further study I have come to the conclusion that the former treatment was incorrect. O. elwendicum differs in having calyx 14-17 mm in flower, to 20 mm in fruit; corolla 18-20 mm or sometimes more.
