The paper presents data on new records of alien and native vascular plant species, that are new for floras of several regions of European Russia, all made in 2024. Ballota nigra is a new neophyte species in the Pskov Region. Crataegus maximowiczii is recorded as naturalized alien species in the Kostroma Region. Ostericum palustre is a rare native species found in the Vologda Region for the first time. Vicia cassubica is a new native species recorded in both the Leningrad Region and in the Republic of Karelia. In addition, we provide data on several important species that previously have been rarely recorded in studied regions, i.e. 2nd record of alien Eragrostis minor for the Pskov Region, 3d record of alien Bidens frondosa for the Pskov Region, 2nd record of native Festuca altissima for the Leningrad Region, new records of native Najas flexilis and N. tenuissima for the Novgorod Region, and a new record of native Agrostis vinealis for the Vologda Region.
