[Wikipedia] Taxonomy: The species was first described in 1875 by Daniel Cady Eaton as Cheilanthes clevelandii. He named it for Daniel Cleveland, the collector of the type specimen, which came from "a mountain about forty miles from San Diego, California".[6] By a strict application of the principle of priority, Oliver Atkins Farwell transferred the species to the genus Allosorus as Allosorus myriophyllus var. clevelandii in 1931, that genus having been published before Cheilanthes.[7] Farwell's name was rendered unnecessary when Cheilanthes was conserved over Allosorus in the Paris Code published in 1956.
