This is a modern account of the lycopod and fern diversity of the region and an essential tool for any future taxonomic or biogeographical study of its flora. Family and generic, as well as species and subspecific names are arranged alphabetically. Accepted names are followed by the author citation and the original publication. Basionyms, homotypic and heterotypic synonyms are provided. The provenance and, where known, the type location are provided for the names and their synonyms. Where available, the locality data, date of collecting, collector and collector's number are given. Many names have been lectotypified, with an indication of the lectotypifying author, year of publication and page number(s), where available. The chromosome number, with a reference, is provided in many cases. The listing of species distribution by country is based on literature surveys and on limited herbarium surveys.
