Contribution to the liverwort flora of Alaska

The annotated list of liverworts collected by the expedition to Southern Alaska in 1992 counts 113 species and one subspecies, including Cephalozia hamatiloba and Nardia pacifica new to Alaska. Scapania obscura is reported for Alaska with reference to the specimen for the first time. The data on the flora of the three studied boroughs were significantly expanded to include 59 species new to Matanuska-Susitna, 51 species new to Anchorage and 20 species new to Kenai. New localities for numerous phytogeographic interesting and/or poorly known species are reported. The distribution of species recently described from Alaska, as well as some poorly studied, mainly amphipacific species, is characterized. образец.
