Abstract

An annotated list of liverworts collected in the Bolshoy Patok River Basin (Pechora River Basin, Yugyd Va National Park, Komi Republic, Russia) is presented for the first time. The list includes 101 species and one subspecies of 53 genera, 27 families, six orders, and two classes (Marchantiopsida and Jungermanniopsida). Data on collecting places, habitats, substrate, and structures associated with reproduction are provided for every species. Solenostoma subellipticum is reported for the first time for the Komi Republic flora. Six species listed in the Red Data Book of the Komi Republic (Arnellia fennica, Heterogemma laxa, Lophozia ascendens, Odontoschisma elongatum, Oleolophozia perssonii, Scapania apiculata) have been found in the flora. Forest habitats and rock outcrops are characterized by the highest taxonomic diversity: 72 and 60 species, respectively. Spruce forests dominate in number of species (38) among the forest formations. Revealed liverworts prefer to grow on rocky substrates and disturbed soil. About 78% of the identified species form reproductive structures.
