Nomenclatural revision and syntaxonomical proposal for wetland peat vegetation in the Valdivian-Magellanian region
Although numerous descriptive studies have been published throughout the 20th century on peat communities in the Southern Cone of South America, the nomenclature applied to the different units recognised often fails to take into account the proposals of previous authors. Our aim is to clarify the no...

Although numerous descriptive studies have been published throughout the 20th century on peat communities in the Southern Cone of South America, the nomenclature applied to the different units recognised often fails to take into account the proposals of previous authors. Our aim is to clarify the nomenclature by applying the rules of the ICPN to propose a current syntaxonomy of the class Myrteolo nummulariae-Sphagnetea magellanici. After a bibliographic compilation of possible peatland associations from the part of South America between parallels 40º and 56º south, under Temperate and Boreal macroclimates, we have collected around 30 names of phytosociological associations and alliances containing an abundance of homonyms and nomina nuda. Following ICPN standards, we have eliminated duplications and established priority names over others, lectotypified some names and rejected others as nomen ambiguum. We have arranged the floristic groups in the recognised associations in synthetic tables, with some nomina nudawhose characterisation we interpret as doubtful, as a proposed syntaxonomical organisation of the phytosociological class.The various communities recognised by the different authors who have worked in the territory can be divided into four physiognomic groups: 1. cushion bogs, 2.
