Myriopteris covillei

Myriopteris covillei, commonly known as Coville's lip fern, is a small fern found in the southwestern United States and on the Baja California peninsula, with an outlying population in southern Oregon. Its leaves grow in clusters and are dissected into beadlike segments; the undersides of the leaf axes are covered with whitish scales that conceal the green tissue of the leaf. One of the cheilanthoid lip ferns, it was usually classified in the genus Cheilanthes as Cheilanthes covillei until 2013, when the genus Myriopteris was again recognized as separate from Cheilanthes. The species usually grows on or near rocks. It is named in honor of the botanist Frederick Vernon Coville, co-collector of the type specimen in 1891....read more on Wikipedia.
