A checklist and census catalogue of British and Irish bryophytes. Updated 2008

The 2008 checklist of British bryophytes lists 1056 species (comprising 4 hornworts, 297 liverworts, 755 mosses), 15 subspecies and 94 varieties, in 304 genera. These are arranged in a full taxonomic hierarchy. The moss classification is broadly similar to that in the current standard flora, but the liverwort classification incorporates many new features resulting from recent genetic studies. Annotations provide literature references for all changes from the standard floras, including taxa newly added or deleted. For each taxon, there is a list of the vice-counties in which it has been found. Vice-county records are distinguished by whether or not there is a post-1959 record in the database of the Biological Records Centre at CEH Wallingford.
