The karyomorphological studies of four species of Anemone were carried out. A. obtusiloba and A. elongata have shown the chromosome consitution 2n=14 while A. vitifolia and A. rivularis 2n=16. On the basis of karyotypic analysis it was pointed out that the structural change in chromosome is one of the basic factor that controls speciation within the genus.
