Discusión taxonómica
This species is distinct with its narrowly deltate fronds, pinnatifid apices, and oblong, acute pinnae. The spores are often a mixture of well formed (having narrow ridges and being short to long-tuberculate) and malformed, suggesting this species is a triploid apomict, at least in Mexico.A
