Boxes of Iris setosa are characterized by the largest diameter and contain the largest number of seeds. Iris sibirica has the lowest values of both indicators. All species in the studied parameters statistically significantly differ from each other. There is a very close correlation between the number of seeds in the boxes and their diameter.
