    A widely distributed species present in Mediterranean and Irano-Turanian regions. In Pakistan, it is fairly common in Balochistan and Chitral.

    A perennial species of dry hill slopes gr owing at varying elevations (5000-13000 ft.).

    A variable species. Various workers have recognized a number of forms on the basis of size of pedicels (forma sessiliflora Kusn., forma elongata C. Winkl.), size of calyx (forma aucheri Griseb.), and size of corolla (forma paviflora Regel & forma grandiflora Regel). It seems that all these forms are not distinct taxonomically.
