Discusión taxonómica

The atropurpureous lustrous stipes and rachises, 3-pinnate blades, proliferous and flagelliform blade apices, and slightly gibbous sorus-bearing segments distinguish this species from the similarly dissected A. cristatum and A. myriophyllum, which are probably not closely related.A
