The Liverworts & Hornworts of the Tristan da Cunha Group of Islands. Mem (105)

Based on historic collections of liverworts and hornworts of the Tristan da Cunha group of islands in the South Atlantic Ocean, and heretofore-unstudied more recent large collections, the authors present information on 145 taxa occurring in the islands. This includes taxonomic and nomenclature remarks, including descriptions of new taxa; specimen citations; literature records; distributions; and ecology. Other features include a history of exploration, a description of the island group's phytosociology, and an assessment of the phytogeographic affinities of the Tristan-group liverworts and hornworts.
