Lorinseria
Lorinseria is a genus of fern in the subfamily Woodwardioideae of the family Blechnaceae. Its only species is Lorinseria areolata (synonym Woodwardia areolata), the netted chain fern, native to eastern North America. The monotypic genus "Lorinseria" has been separated from "Woodwardia" in the Pteridophyte Phylogeny Group classification of 2016 (PPG I), on the basis of its anastamosing veins and lobed frond form, as well as its more marked frond dimorphism. However, the genus name "Lorinseria" appears to be a later homonym of "Lorinsera" , and will need to be replaced or conserved. The sterile fronds are 40–60 cm long, and  the fertile fronds 50–70 cm long. It is superficially similar to "Onoclea sensibilis" and sometimes confused with it. Distribution and habitat. 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. 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.
