ABSTRACT. The first finding of Sphagnum tenellum, a species with a well-defined oceanic distribution, on a ridge-hollow bog in the centre of the taiga zone of Western Siberia is reported. Its distribution in Russia is analyzed and re-assessed. The geobotanical descriptions of plant communities with Sphagnum tenellum from Western Siberia and South Siberian mountains are presented. It has been shown that communities with Sphagnum tenellum in montane mires in South Siberia are most similar in composition and environmental conditions to finds from the highlands of Scandinavia, while the new location of Sphagnum tenellum in the taiga zone of Western Siberia is fully consistent with the ecologo-cenotic amplitude of the species in the north of West European plains and North-West Russia.
