Abstract

Thelypteridaceae is a worldwide group of nearly 1,000 species of ferns with a complex taxonomic history. Generic circumscriptions in the family have been a subject of controversy for more than 50 years. There are two views concerning the best way to circumscribe genera within the family: most New World fern specialists recognize only one (Thelypteris with many subgenera) to five genera while most Old World specialists recognize about thirty. To better understand how Thelypteris subgenus Amauropelta is related to other members of the family and to gain a preliminary understanding of sectional classification within the subgenus, plastid DNA regions (rps4, the rps4-trnS spacer, and the trnL-trnF spacer) were analyzed to infer the phylogeny and evaluate the phylogenetic position of Thelypteris subgenus Amauropelta. Subgenus Amauropelta is distributed mainly in the Neotropics and includes about 200 species. The inferred phylogeny provides strong support for the monophyly of subgenus Amauropelta and illustrates even more the need for a new, and cohesive, classification system for Thelypteridaceae. The resulting phylogeny suggests that the best approach towards a stable classification of the family would be to recognize Amauropelta at the generic rank and to recognize Thelypteris in a narrow sense. The phylogeny, however, did not provide adequate resolution to fully clarify relationships among the sections of Thelypteris subgenus Amauropelta, but it does suggest that some sections are not monophyletic, e.g., Amauropelta, Uncinella, Lepidoneuron, and Adenophyllum.
