A new record of the rare species Colchicum fominii (Colchicaceae) in Odesa Region is reported. The new locality was recorded on the steppe slope in the Kuchurhan River valley near Hayivka village, Rozdilna District. Its total area was 60,000 m2, with the maximum plant density of 12 individuals per 1 m2. In order to fully assess the state of the population of C. fominii, it is recommended to carry out studies in spring during the formation of leaves and fruits, as the number of flowering plants in a locality depends on the amount of precipitation before or during flowering. At present, the locus classicus of C. fominii has been transformed into a synanthropic habitat with intensive overgrowth of trees, shrubs and weeds, which negatively affects the general state of the population of C. fominii. The new habitat of C. fominii has a high potential for the development and conservation of the species in the Kuchurgan River valley and requires certain protection measures, in particular, the establishment of a botanical reserve.
