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),[2] on the basis of its anastamosing veins and lobed frond form, as well as its more marked frond dimorphism.[citation needed] However, the genus name Lorinseria appears to be a later homonym of Lorinsera Opiz, and will need to be replaced or conserved.[2]

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.
