Myriopteris windhamii, formerly known as Cheilanthes villosa,[2] is a species of lip fern, with the common name villous lipfern.

Myriopteris windhamii is a medium-sized tufted fern growing from a short rhizome with bicolored scales.

[4] Myriopteris windhamii is similar in appearance to Myriopteris lindheimeri but can be distinguished by bicolored rhizome scales, costal scales not markedly ciliate, and hairs attached directly to the adaxial (upper) leaf segments (not just growing over the upper leaf surface as in Myriopteris lindheimeri).

[4] Myriopteris windhamii is native to the southwestern United States where it grows in rocky mountains and deserts.

For example, it is found along with the elephant tree, Bursera microphylla, and other desert species in the Waterman Mountains of southeastern Arizona (northern Pima County).
