Discusión taxonómica
See discussion under A. auritum. Adams (in Davidse et al., 1995) recognized A. rigidum Sw. (Kongl. Vetensk. Acad. Handl. 1817: 68. 1817), type from southern Brazil (Freyreis s.n., S, photo UC!), as distinct from A. cuspidatum and ranging into southern Mexico and Central America. We are doubtful that the two species, both of which are 2-pinnate or sometimes slightly more divided, are specifically different, and even if they are distinct, we have seen nothing in Mexico that quite matches the Brazilian type. We therefore choose not to recognize this species from Mexico. Asplenium cuspidatum has been variously circumscribed, in its tortuous history, often more broadly, to include what we have here called A. fragrans (which see for further discussion).A
