Bryophyte flora of Sao Tome e Principe Archipelago (West Africa): annotated catalogue

An updated catalogue of the bryophytes of Sao Tome e Principe Archipelago is presented. Occurrence data on both islands for each species are reported, based on a critical assessment of the literature since the first botanical expeditions in the 19(th) century up to June 2010. The references are chronologically listed for each species, and all old herbarium specimens revised or identified are also indicated. In addition, two lists (mosses and liverworts-hornworts) of known synonyms are provided. Two hundred twenty bryophyte taxa are listed (91 mosses and 129 liverworts-hornworts), while twenty taxa are excluded or their occurrence considered very improbable. The species diversity and endemics are also analysed for each island.
