The difficult natural conditions of the Purovsky District of the Yamal-Nenets Autonomous Area determine the insufficient floristic knowledge of this territory. The high degree of anthropogenic transformation of the vegetation of the area makes it necessary to identify habitats of rare plant species in order to preserve and restore their numbers. The expedition studies carried out by the authors in 2019 allowed us to obtain new information about the distribution of 6 rare plant species. Three species (Corallorhiza trifida Chatel., Botrychium multifidum (S.G. Gmelin) Rupr., Neottia cordata (L.) Rich.) have small locations within the Yamal-Nenets Autonomous Area and were first found in the Purovsky district. For three species (Goodyera repens (L.) R. Br., Dactylorhiza fuchsii (Druce) Soó, Lycopodiella inundata (L.) Holub), new locations have been identified that are significantly removed from previously known ones. Three species are included in the main list of the Red Book of the Yamal-Nenets Autonomous Area (Corallorhiza trifida, Dactylorhiza fuchsii, Lycopodiella inundata), two - in the Appendix to it (Botrychium multifidum, Goodyera repens). A rare species of the Orchidaceae family, Neottia cordata, was previously known from two localities in the mountainous part of the Yamal-Nenets Autonomous Area; two new localities were identified in the Purovsky district. In one of them, a large population of Neottia cordata was noted, which is of particular importance for the conservation of the species, because Currently, the number of localities in the Russian part of Neottia cordata is decreasing. The species needs protection and should be included in the Red Book of the region. The presented data complements information on the distribution of rare plant species and is necessary for further monitoring.
