Bryophyte flora of the Dickson village area was studied during five field seasons.The list includes 90 species and 7 infraspecific taxa of liverworts and 249 species and 2 varieties of mosses.This is the greatest number among local floras published for Asian Arctic.It exceeds previously published moss floras of the nearby areas by about hundred species.It is partly caused by application of new species concepts, which appeared as a result of revisions involving molecular phylogenetic data.However, it also demonstrates strong under-exploration, and, consequently, underestimation of bryophyte diversity and need in its conservation.The present study shows that the number of species in local floras does not decrease northward within the tundra zone.Moreover, bryophyte flora of the arctic tundra biome houses the previously neglected or only recently recognized taxonomic diversity.An annotated list of species is provided, аlong with comments on the problematic taxa and specimens. РезюмеБриофлора окрестностей пос.Диксон и расположенной в 17 км южнее бухты Медуза, изученная в течение пяти полевых сезонов, включает 90 видов и 7 внутривидовых таксонов печеночников и 249 видов мхов и по числу выявленных таксонов мохообразных превосходит все ранее опубликованные локальные бриофлоры азиатской Арктики.Представленный список снабжен комментариями к проблемным или интересным с точки зрения фитогеографии таксонам или образцам.Краткое сравнение с ранее опубликованными бриофлористическими исследованиями показывает, что в пределах тундровой зоны разнообразие мохообразных на уровне конкретных флор не уменьшается к северу.Хотя такое большое число выявленных видов, в том числе
