Abstract

According to currently available data, 159 species of genus Taraxacum F. H. Wigg. were reported for North-West Russia (i. e. within the city of Saint-Petersburg, Leningrad Region, Pskov Region, and Novgorod Region), but among them the specimens of only 126 species were identified with reliability. Five Taraxacum species are reported in this article as new for North-West Russia, and for Russia as a whole: T. acervatulum Rail., T. hepaticum Rail., T. macranthoides G. E. Haglund, T. sertatum Kirschner, H. Øllg. et Štěpánek, T. subxanthostigma M. P. Christ. ex H. Øllg. All of them belong to the section Taraxacum. Newly recorded species are illustrated and the list of their herbarium specimens is provided. A brief summary of the taraxacological studies undertaken earlier in North-West Russia is presented as well.

Key words: Taraxacum, apomictic vascular plants, biodiversity, flora of Russia, floristic novelties, Leningrad Region, Pskov Region, Novgorod Region
