Appearance
It is superficially similar to ''Onoclea sensibilis'' and sometimes confused with it.
Naming
It is usually treated in the genus ''Woodwardia'', in the eupolypods II clade of the order Polypodiales, in the class Polypodiopsida. It is sometimes transferred to the monotypic genus ''Lorinseria'' as ''Lorinseria areolata' C.Presl, on the basis of its anastamosing veins and lobed frond form, as well as its more marked frond dimorphism; however, the genus name ''Lorinseria'' is invalid, being an orthographical variant of ''Lorinsera'' Opiz.
Distribution
This species is native to the southeast United States, but ranges all the way up the East Coast of the United States and Canada to southern Nova Scotia.Habitat
It favors moist, sandy, acid soils, and has appeared in areas in the interior of the US around acid mine seeps, thus being one of the few species to benefit from acid mine drainage.References:
