Europe, C. U.S.S.R., Caucasia, Siberia, N. Iran, Turkestan. Euro-Sib. element. The distinctions between C. oreades and C. dahuricum (size, leaf shape, etc.) break down frequently. C. hemschinicum is the name applied to specimens bearing bulbils in their leaf axils. They differ in no other way (morphologically) from typical C. dahuricum. The species should be studied cytologically.
