The article provides new information on the distribution of the rare species Oxytropis sordida (Willd.) Pers. in the Leningrad Region. It occurs only in the Priozersky District, in the central and north-eastern parts of the Karelian Isthmus. Just about 30 years ago, the occurrences of this species in disturbed habitats were singular, and some 40 years ago it was found exclusively in natural habitats of the region – in light true-moss-type pine forests on kames and eskers, less often on sandy moraines. According to survey data from 2023, O. sordida currently grow mostly in disturbed habitats with sandy substrates (in roadsides; in a worked out sand quarry). Local populations in undisturbed habitats are represented by one to several dozen specimens and are in satisfactory or poor condition.
