Contribution to the bryophyte flora of Svalbard: hepatics of Barents Island

The annotated list of hepatics of Barents Island (Svalbard archipelago) was compiled based on the collections by Savchenko, literature data and Arne Frisvoll’s collection in TRH. A total of 35 species, three subspecies and four varieties are recorded for Barents Island. Fifteen taxa are listed as new for Barents Island and four taxa are listed as new for Svalbard, including Lophozia silvicola, Lophozia subapiculata, Preissia quadrata subsp. hyperborea and Lophoziopsis excisa var. elegans. A new combination Trilophozia quinquedentata var. turgida is made. Annotations to the species include distribution, description of habitats, and some morphological characteristics of the studied specimens. Peculiarities of the hepatic flora of the island and the distribution in Svalbard are discussed.
