Cheilanthes covillei, reclassified as Myriopteris covillei, [1] is a species of lip fern known by the common name Coville's lip fern.


This plant is native to California, Baja California, Arizona, Oregon, and Utah. [2] It grows in rocky crevices in the mountains and foothills.

In California it is found in Chaparral, Yellow pine forest, Pinyon-juniper woodland, and Joshua tree woodland habitats. [1]

Description

This fern has green leaves which may be up to 4-pinnate, that is, made up of leaflets that subdivide 3 times, such that the leaflets are layered with overlapping rounded segments. The leaves have a bumpy, cobbled look.

The undersides of the leaves have scales which are lengthened outgrowths of the epidermis. Tucked under the scales are the sporangia, which make the spores.
