Discusión taxonómica
(In relation to the synonym Lellingeria mitchellae) This species is readily distinguished from congeners in Mexico by the conspicuously setose sporangial capsules. In blade form and venation (costae with a single acroscopic branch) it more closely resembles species of Micropolypodium, but species of Micropolypodium have lighter colored rhizome scales, dark setae on the blades, and glabrous sporangia. Unpublished molecular data suggest that this species may be better placed in the group of Terpsichore cultrata (Ranker et al., ined.).A
