Coville's lip fern 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 dark to medium 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 edges of the leaflets are curled under (forming a false indusium) and their undersides have wide scales which are lengthened outgrowths of the epidermis. Tucked under the scales and false indusium are the sporangia, which make the spores.
Taxonomy
Myriopteris covillei is one of the parents of the fertile allotetraploid Myriopteris intertexta.[3][4][5]
