According to our own observations, herbarium materials and literature data, the distribution of Iris pineti- cola Klokov — an endemic forest-steppe species included in the Red Data Book of Ukraine in the status of “vulnerable” was analyzed. Data on its taxonomic status are given, distribution map is made (geographical coordinates are restored on the basis of materials of the National Herbarium of Ukraine (KW), herbarium of V. N. Karazin Kharkiv National University (CWU), as well as literature data), range and population data are analyzed. It is established that I. pineticola is distributed in the Right-Bank and Left-Bank Forest-Steppe, occasionally entering the north part of the steppe and the valley of the Siversky Donets. Grows in forests, artificial pine plantations on sandy terraces of rivers. According to own data and analyzed literature, I. pineticola populations are stable.
