Discusión taxonómica
The name A. cuspidatum has often been applied to the species here called A. fragrans, e.g., by Smith (1981), Mickel and Beitel (1988), and Mickel (1992), but Adams (in Davidse et al., 1995) regarded it as distinct, and we now agree. Most authors have treated it as a synonym of A. cuspidatum var. tripinnatum (e.g., Morton & Lellinger, 1966, for Venezuela; Tryon & Stolze, 1993, for Peru; Proctor, 1985, for Jamaica). Asplenium fragrans is a more dissected species, having blades that are 3–4-pinnate, rather than 2-pinnate to 2-pinnate-pinnatifid at the bases. See additional discussion under A. auritum. Juvenile or young sterile specimens have nearly filiform ultimate segments, e.g., Mickel 4140, 5275 (UC), from Oaxaca.A
