Abstract—The species composition of diatom algae in the Polistovo–Lovatskii sphagnum tract (Rdeiskoye bog,
Novgorod oblast) \are studied. The systematic and ecological–geographical analyses of the flora are performed. A
total of 256 species and intraspecific taxa differing in ecological specificities and frequencies of occurrence in sam-
ples are revealed. A considerable number of centric diatoms is found. It is shown that primary and secondary dia-
tom communities are formed in large sphagnum tracts. The horizontal heterogeneity of diatom communities in
sphagnum bog is revealed. The species diversities of diatom algae in different bogs are compared.

Key words: Polistovo–Lovatskii tract, Rdeiskoye bog, Bacillariophyta, flora.
