Discusión taxonómica
(In relation to the synonym) Thelypteris concinna is distinguished from all other members of subg. Amauropelta in Mexico by having minutely setulose sporangia. In laminar pubescence T. concinna is similar to T. cinerea, but differs from that by the exindusiate sori and a greater number of reduced proximal pinnae. It is by far most common in Chiapas, Oaxaca, and Veracruz, with more than 60 collections seen; collections from all other states in Mexico are fewer than half this number.A
