Abstract

Investigations of South-western geobotanical district of Sakhalin Island, which is classified as a separate subzone of dark coniferous forests with an admixture of broad-leaved species and corresponds to Krillon floristic district, revealed a number of new aquatic vascular plant species for that area (Lemna turionifera, Myriophyllum verticillatum, Potamogeton gramineus, P. manchuriensis, Stuckenia pectinata, Utricularia minor, U. × ochroleuca). There is also a novelty for the South-Sakhalin lowland geobotanical district (Myriophyllum spicatum). All these taxa are known from other geobotanical districts of Sakhalin. The additions to the flora of the South-western district, which is well surveyed by botanists, indicate not floristic uniqueness of the subzone of dark coniferous forests with an admixture of broad-leaved species, but rather a poor knowledge of the Sakhalin Island aquatic flora.
