Land of retreating glaciers – checklist of liverworts on Svalbard

The checklist of liverworts of the Svalbard archipelago contains all published data on the occurrence of liverworts in the Svalbard archipelago. The list includes 105 species, five more reported species that only doubtfully occur there, and 51 species previously listed for the archipelago that are excluded from Svalbard. In addition, the locations of 67 species new to different regions of the archipelago are reported. Two species, Neoorthocaulis hyperboreus and Riccardia chamedryfolia , are listed as new to the archipelago. Two old names are typified and synonymized with taxa common on Svalbard. lycopodioides var. obliqua Many, es-pecially older, reports to Barbilophozia hatcheri not of any confirmed Svalbard although several specimens in TRH is named Barbilophozia lycopodioides , but they in need of revision. Specimens in TRH that we have seen seem to deviate morphologically from what is found in boreal and alpine areas of Scandinavia. Further studies are needed to clarify the taxonomic status of these specimens.
