Bryophytes of the ‘Retno’ Nature Reserve (Brodnickie Lake District, N Poland)

The paper provides information about 7 species of liverworts and 51 species and 1 variety of mosses collected within the ‘Retno’ Nature Reserve. The diversity of the flora of the reserve is low without any particular bryological values. The most interesting species are Bryum rubens and Orthodicranum tauricum. There are 9 species partially protected in Poland and 1 endangered, however, most of them are common bryophytes throughout the country.
