Removing Adiantum vivesii From the Federal List of Endangered and Threatened Plants

We, the U.S. Fish and Wildlife Service (Service), propose to remove the plant Adiantum vivesii (no common name) from the Federal List of Endangered and Threatened Plants (List). Our review of the best available scientific and commercial data, including peer reviewer comments received on the 5-year status review (2008), indicate that A. vivesii is not a distinct species, but rather a sterile hybrid that does not have the capacity to establish a lineage that could be lost to extinction. Therefore, A. vivesii is not a listable entity under the Endangered Species Act of 1973, as amended (Act).
