Description

This fern is a dark-green color with leathery, pinnately compound leaflets. Its name comes from the characteristic sword-like shape of its leaflets. The leaves are tapered at both ends and have opposite leaflets that sit in two rows all the way down the light-brown colored stem that sits about three feet high. They grow straight from the ground in swampy, moist habitats and are commonly found in the midst of other species.
