Discusión taxonómica
This species and A. wrightii Baker in Hooker & Baker, of Cuba, Bahamas, and Florida, form a distinct species group characterized by small, dimorphic, thin-textured fronds and spores with reticulate ridges. Anemia cicutaria is distinct by the hairiness and segment shape of its blades, the fertile fronds being more open, and the sterile fronds more dissected. The spore ridges are finely anastomosing, making the spores appear coarsely pitted rather than striate.A
