Discusión taxonómica
This species, with 1-pinnate blades and non-auriculate to slightly auriculate pinnae, is part of a related group of species with castaneous to atropurpureous, lustrous stipes and long, flagelliform, proliferous blade apices. This complex includes taxa that are progressively more divided, ending with the fully 3-pinnate A. uniseriale. For discussion of this complex see under A. radicans. In Mexico, Asplenium cirrhatum is most closely related to the 1-pinnate A. yelagagense (which see). Mickel and Beitel (1988) reported this species from Chiapas, but we are now unable to verify this record.A
