This ferns' fronds are thin and light green with the pinnules having wavy edges and fringed. They also have, on the underside of the fertile ones, large dark brown patches covering the sori. The pinnae are about 1" long and the whole plant grows to about 7" long by 2" wide. In Arizona and maybe in other states where this plant is native to, it's occurance ranges from 2000-9000 ft. elevation and grows in the shade of rock ledges and cliffs. This is mostly a rock dwelling fern and amongst other places it can be found at Woods Canyon Lake in Arizona.
It is native to CA, AZ, NM, CO, OK, & TX in the USA.
