Information about findings of vascular plants of the Srednij Isle, located in Kandalaksha Bay of White Sea (66°16'50"–66°17'55" N и 33°37'50"–33°42'40" E) is given. Cystopteris montana (Lam.) Bernh. ex Desv., Diphasiastrum montellii (Kukkonen) Miniaev et Ivanenko, Drosera × obovata Mert. et Koch., Eleocharis mamillata (H. Lindb.) H. Lindb., Heracleum sibiricum L. var. longifolium C. Koch, Huperzia selago (L.) Bernh. ex Schrank et Mart., s. str., Lycopodium lagopus (Laest.) Zinserl. ex Kuzen., L. pungens La Pyl. ex Iljin, Melampyrum hians (Druce) Tzvel. are recorded for the first time. New locations are indicated for other rare species: Actaea spicata L., Allium schoenoprasum L. subsp. sibiricum (L.) Hartm., Arctous alpina (L.) Niedenzu, Carex capitata L., C. paleacea Wahlenb., C. vesicaria L., Cypripedium calceolus L., Cystopteris fragilis (L. ) Bernh., Diphasiastrum complanatum (L.) Holub, Diplasium sibiricum (Turcz. ex G. Kunze) Kurata, Dryopteris carthusiana (Vill.) H. P. Fuchs, Equisetum scirpoides Michx., Lycopodium clavatum L., Naumburgia thyrsiflora (L.) Reichenb., Plantago shrenkii C. Koch., Poa trivialis L., Potamogeton pectinatus L., Ranunculus hyperboreus Rottb., Rosa majalis Herrm., Sparganium angustifolium Michx., Veratrum lobelianum Bernh. Hypoarctic species — Arctous alpina, Diphasiastrum montellii, Lycopodium lagopus, L. pungens, Ranunculus hyperboreus — may be ascribed to vanishing species. They are located on territories with undeveloped ground cover and slip out of isle’s flora during natural endogenetic succession of vegetation. Extinction of Plantago shrenkii is probably connected with its hybridization with polyzonal species P. maritima — the first is absorbed by the last in the process of back crossing. Wide spreading of these hypoarctic species in this region took place apparently in more severe conditions of Holocene. Refs 13.
