Discusión taxonómica

Asplenium salicifolium is closely related to the much more common A. auriculatum, and differs from that in the larger fronds with more remote and larger pinnae 5.5–9 cm long, more teeth on the acroscopic pinna margins (17–39), often 2-forked veins, and more pairs of sori per pinna (7–15). Proctor (1985: 378) regarded A. salicifolium and A. auriculatum as varieties of a single species. Torres C. 8664, cited above, is somewhat intermediate between the two species. Adams (in Davidse et al., 1995) recognized a second variety, var. aequilaterale (Christ) C. D. Adams, confined to Costa Rica and Panama.A
