Discusión taxonómica
Doryopteris is a genus of about 30 species, in dry, rocky, tropical regions, mostly of the Planalto of southern Brazil, with five endemic to Madagascar, and one pantropical. There are only two species in Mexico, both rare. Doryopteris is distinct by the deeply palmately lobed blade with marginal sori. Molecular studies (Gastony & Rollo, 1995, 1998) have shown Doryopteris to be most closely allied to Trachypteris of South America and Pellaea calomelanos of Africa.A
