Fendler's lip fern

Myriopteris fendleri, known as Fendler's lip fern, is a small to medium-sized fern of the southwestern United States and northwestern Mexico. Its leaf is three times divided. One of the cheilanthoid lip ferns, it was usually classified in the genus Cheilanthes as Cheilanthes fendleri until 2013, when the genus Myriopteris was again recognized as separate from Cheilanthes. It grows on rocky ledges and slopes, often in pine forests. The species is presumably named for Augustus Fendler, who collected the type specimen.
