Myriopteris allosuroides

Myriopteris allosuroides is a small to medium-sized fern endemic to Mexico. Its leaf is up to three times divided into elliptical segments. Unlike many members of its genus, its rachides are grooved on the upper surface and largely free of hairs or scales. One of the cheilanthoid lip ferns, it was usually classified in the genera Cheilanthes or Pellaea until 2013, when the genus Myriopteris was again recognized as separate from Cheilanthes. It typically grows on dry, rocky slopes over acidic, particularly basaltic, rock.
