A comparative analysis of ten taxa of the genus Iris was carried out based on biomorphological and karyological characteristics. The assessment of morphological variability structure allowed to identify taxonomic indicators common to the analyzed species and characterized by relatively low common and consistent variability: length and width of the outer perianth lobes, length and width of the inner perianth lobes, length of the stamen filament, anther and pistil, width of the fruit, as well as length and width of the seed. Based on the constructed phylogenetic relationships based on the identified taxonomic features, the studied species were grouped into conditional groups: 1. I. carthaliniae, I. halophila, I. spuria; 2. I. lactea; 3. I. pseudacorus, I. setosa; 4. I. sibirica, I. sanguinea; 5. I. graminea; 6. I. pumila, which is also consistent with chromosome numbers found by us in somatic tissue.
