Myriopteris yatskievychiana

Myriopteris yatskievychiana is a small fern endemic to the Mexican state of Sonora. It is known only from a single collection. While superficially similar to golden lip fern, a widespread species in Mexico, differences in its coating of hairs and its small size make it distinctive. It is pinnate, with lobed pinnae covered on both sides with straight white hairs. One of the cheilanthoid lip ferns, it was usually classified in the genus Cheilanthes as Cheilanthes yatskievychiana until 2013, when the genus Myriopteris was again recognized as separate from Cheilanthes. The type collection was made in a sycamore forest in a canyon.
