Discusión taxonómica
Pteris podophylla is closely related to P. erosa and P. orizabae; the characters in the key distinguish the three. The abaxial surfaces of P. podophylla, with erect, terete, concolorous hairs, are clearly different from surfaces of P. orizabae, which have long, flaccid hairs or are glabrous.A
