Cheilanthes bonariensis (Willd.) Proctor

Cheilanthes bonariensis (Willd.) Proctor. Myriopteris aurea, the golden lip fern or Bonaire lip fern, is a medium-sized fern native to the Americas, a member of the family Pteridaceae. Unlike many members of its genus, which are relatively lacy, its leaf is only dissected into lobed leaflets (pinnae), which are hairy both above and below. One of the cheilanthoid lip ferns, it was classified in the genus Cheilanthes as Cheilanthes bonariensis until 2013, when the genus Myriopteris was again recognized as separate from Cheilanthes. It typically grows on dry, rocky slopes, and ranges from the southwestern United States through Mexico, where it is common and widespread, south and east through Central and South America as far as Chile and Argentina. The common names refer to the color of the hairs on the upper surface of the leaves, and to early collections around Buenos Aires, Latinized as "Bonaire".
