ON SOME RARE VASCULAR PLANT SPECIES FROM THE ISLANDS OF THE VYBORG BAY (LENINGRAD REGION)
Data on the most interesting floristic records of vascular plant species on the islands of the Vyborg Bay are represented. Detailed floristic investigations on 86 islands in the Vyborg Bay were carried out by the author in 2005-2011, and 620 vascular plant species were recorded from the area. The list of the most interesting records includes 29 rare in the NW Russia vascular plant species, 20 of them are threatened in the region and included in the Red Data Book of Nature of Leningrad Region (2000). New information about habitats of some species (Draba incana L., Melica picta K. Koch) is provided. Before the author's research on the islands, Draba incana L. was known in the area only by old findings of Finnish botanists and regarded as an extinct species in Leningrad Region. Melica picta K. Koch is recorded for the first time on the island of the Vyborg Bay.
