Myriopteris covillei (Coville's lip fern) is a native California herb in the Pteridaceae family, recognized by dark rhizome scales and large covering scales.

Coville's lip fern is a California native perennial found in the Coast Ranges, Sierra Nevada, Sutter Buttes, San Francisco Bay Area, southern Coast Ranges, eastern southern Coast, Transverse Ranges, Peninsular Ranges, northeastern Sierra Nevada, western Mojave Desert, desert mountains, and western desert regions in rock crevices and rock bases from 600 to 2,400 meters elevation. Its dark green fronds are 8 to 22 centimeters long with intricate, highly dissected leaflets that create a delicate, lacy appearance. Growing with a short-creeping rhizome, the fern develops stems with distinctive dark brown or black scales, some featuring narrow light brown margins. Its leaves are complex, with 3 to 4 levels of pinnate divisions, featuring small, nearly round segments densely covered with overlapping scales that obscure the leaf surface. The fern thrives in both sunny and shaded environments, with fronds characterized by white to red-brown scales and a unique, compact growth structure.
