Discusión taxonómica
(In relation to the synonym) Thelypteris deflexa differs from other members of subg. Amauropelta in Mexico by the combination of exindusiate sori, nearly or quite glabrous rachises and costae abaxially, and relatively few pairs of reduced proximal pinnae. Breedlove 31739 (DS), from Chiapas, is atypical in bearing sessile reddish glands on the blades and receptacles, fibrillose scales on the costae and costules abaxially, and small aerophores at the pinna bases.A
