Cheilanthes Aemula

Myriopteris aemula, the Texas lip fern or rival lip fern, is a medium-sized fern of Texas and Mexico. The leaf is up to four times dissected into elliptical segments. Unlike many members of its genus, its leaves have a few hairs on upper and lower surfaces, or lack them entirely. One of the cheilanthoid lip ferns, it was classified in the genus Cheilanthes as Cheilanthes aemula until 2013, when the genus Myriopteris was again recognized as separate from Cheilanthes. It typically grows on limestone rock.
