The species is commonly found in freshwater marsh and swamp conditions in tropical or subtropical locations. It can also be found wet prairies, moist pine woods, and sometimes in forests[3] Specifically, in Florida the recorded habitat for this fern is moist and shady places.[4] The range for this fern species is from Florida to South America and has been recorded in Malaysia and Australia.[3]
It has shown good resistance to lead contamination when growing on coal mine tailings.[5]
This fern is comparable to other ferns that consist of a stipe growing from the rhizomes and pinnae growing from the rachis.[3] The entire above-ground specimen is called the frond. The fronds for this species are monomorphic and typically are about 30-50 cm in length and 7-16 cm wide.[3] This means that this fern can grow a bit more than four feet tall. At the base, the stipe is usually light brown, sometimes darker at the base, typically 10-70 cm long, and appears cylindrical.[3] The rhizomes form horizontally, even sometimes climbing tree trunks, and are covered in dark brown scales.[3] There is the presence of spores which are located on the underside of the pinnae, usually tan to brown in color. Additionally, there is a central costa that runs the length of the pinnae.[3]
This fern species has not been evaluated for conservation measures.[6] However, this species has been utilized for wetland restoration projects.[4]
