From Wikipedia, the free encyclopedia
Cheilanthes covillei is a species of lip fern known by the common name Coville's lip fern. This plant is native to the southwestern United States and Baja California, where it grows in rocky crevices in the mountains and foothills. 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.
