The data were obtained through a review of literature sources and during numerous botanical expeditions conducted by the authors in the Kostanay Region. All collected specimens are deposited in the Herbarium of Kostanay Regional University (KSPI). This article presents precise locality data for endemic and rare plant species of the region, which may contribute to improving their protection and to the development of targeted conservation measures.
