Discusión taxonómica
Asplenium macilentum Klotzsch ex Kunze (1857) was regarded as a distinct species, also occurring in Mexico, by Adams (in Davidse et al., 1995). He excluded A. monodon from Flora Mesoamericana (which we would not) and characterized A. macilentum as having reniform spores, 64 per sporangium. The lectotype of this is of unknown provenance (selected by Morton & Lellinger, 1966: 18, B-Willd. 19890, microfiche UC!), is similar in form, and may also belong in synonymy under this species (Smith, 1981: 48); however, until spores of the lectotype can be examined, it would be imprudent to place the name. Some specimens from northern South America (especially Venezuela) with the morphology of A. macilentum have large, globose spores, like those of A. monodon, while others have small, reniform spores, like those of A. auritum sensu stricto. A plant identified as A. macilentum from Trinidad was reported as 2n=288, apogamous, by Walker (1985), but Adams (in Davidse et al., 1995) stated that all material in the A. auritum complex from Trinidad was referable to A. monodon. Nearly all plants identified by Adams as A. macilentum from Central America we regard as A. auritum, including those he cited (1995: 309) from Chiapas, Belize, Honduras, and Panama.A
