Discusión taxonómica
Mexican material belongs to var. concolor. Tryon (1942) was uncertain of the relationships of this species because of its free venation. Tryon and Tryon (1982) transferred this species to Cheilanthes, but molecular data (Gastony & Rollo, 1995) have shown its proper place is in Doryopteris.
Doryopteris concolor differs from D. palmata by its free veins and glabrous stipes.
