C. & E. Europe, S. Russia, Caucasia. Pojarkova (in Fl. URSS 9:450, 1939) considers C. curvisepala to be synonymous with C. kyrtostyla Fingerh., whereas Franco (in Fl. Europaea 2:75, 1968) treats C. kyrtostyla as a hybrid between C. calycina sensu stricto and C. monogyna, occuring only in N.W. Europe. Gross-heim records C. kyrtostyla from A9 Çoruh (nr. Posof, Grossheim 5: map 45) and considers it to be widespread in Caucasia. These records may well refer to C. curvisepala. This species probably hybridizes with C. monogyna, C. meyeri and C. microphylla. A record of C. calycina Petermann (Deutschl. Fl. 176, 1849) from 'Phrygia, Salizar, Warburg 114' (Diapulis, op. cit. 65) probably refers to this species.
