Abstract
For the first time for the flora of Omsk Region, a representative of the steppe halophyte complexes Camphorosma lessingii from the Chenopodiaceae family is indicated. The nearest findings of this species are known in Novosibirsk Region and in the north of the Republic of Kazakhstan. The article also contains data on the new locations of 7 rare and protected species of vascular plants for the territory of Omsk Region: Allium ramosum L., Campanula bononiensis L., Cleistogenes squarrosa (Trin.) Keng., Galatella divaricata (M. Bieb.) Novopokr., Nitraria sibirica Pall., Stipa praecapillata Alechin, Vincetoxicum sibiricum (L.) Decne., discovered during field studies in 2021-2022. The article justifies proposals to change or confirm the current security status for Allium ramosum, Camphorosma lessingii, Galatella divaricata, Nitraria sibirica, Stipa praecapillata - 1 (E), Campanula bononiensis - 2 (V). Due to poor knowledge and a small number of populations, it is proposed to include Cleistogenes squarrosa and Vincetoxicum sibiricum in the list of species that need special attention to their condition in the nature.
