A caryosystematic study ofFritillaria obliqua-complex (F.obliqua, F. tuntasiaand F.ehrhartii)endemie in Greece is presented. In a new combination F.tuntasiais considered as a synonyme of F.obliqua.Three populations of F.obliqua(2n= 24 + 0–3B) and three ofF. ehrhartii(2n= 24 + 0-lB) are studied cytologically and their karyotypes and idiograms are given. The geographical distribution of the two species (F. obliquaandF. ehrhartii) suggests a vicariation character.
