• A number of reference works are quite specific about which species have which common name out of the synonym list above, but different references assign them to different species-there doesn't seem to be complete agreement on any one species across even most of the references. The most common assignments for "rabbit's-foot fern" seem to be Davallia canariensis, Davallia fejeensis, and Phlebodium aureum, while "bear's-foot fern" seems to be reserved for former "Humata" species such as Davallia tyermannii- but all of the species have been named "rabbit's-foot fern" in at least one work and all of them have been given one of the other names in at least one work.
