Genus Thelypteris is a collective term used to describe a group of ferns that belong to the family Thelypteridaceae. As with any taxonomic classification, there are alternate names or synonyms that scientists use to refer to the same grouping. Some of the synonyms for Genus Thelypteris include the names Goniopteris and Amauropelta. These names were used in earlier classification schemes but have since been abandoned in favor of the name Thelypteris. It is important to note, however, that the synonymy of a species or grouping can be subject to change as scientists continue to study relationships between organisms and refine classification systems.
