New and rare for Karelia vascular plants.
Information on seven species new for Karelia, viz. native Carex obtusata, accidentally introduced Cicer arietinum, Falcaria vulgaris, Galanthus nivalis and escaped Digitalis purpurea, Gadellia lactiflora, and Ribes alpinum is provided. The finding of Carex obtusata, a species protected in many regions of European Russia and in some European countries, at a large distance from the nearest known localities is of particular interest. Data is given on new locations of eight very rare species, previously known in Karelia in not more than three localities, including aliens Cardamine flexuosa, Cerastium glomeratum, Hordeum glaucum, Papaver croceum, and Papaver dubium. After a gap of more than 70 years, the regionally red-listed Botrychium matricariifolium and Spergula morisonii, as well as the presumably alien species Agrimonia eupatoria were re-discovered. Some of these species (e. g. Cicer arietinum, Falcaria vulgaris) are found in their northernmost known localities in Russia or even Europe.
