Myriopteris scabra, commonly known as rough lipfern, is a species of cheilanthoid fern native to Mexico and the south-western United States (Texas).

[2] Myriopteris scabra grows from a short creeping rhizome, usually 4–7 mm in diameter with brown scales.

The rachis has scattered linear-lanceolate scales and dimorphic pubescence, abaxially sparsely hirsute, adaxially covered with tortuous appressed hairs.

[3] Myriopteris scabra is native to northern Mexico, the Yucatan Peninsula, and to central and western Texas, extending north into Oklahoma.

[4][5] These species have ranges in the southern United States, Mexico, and Caribbean islands.
