Genus Summary: A monotypic genus, perennial herb, of e. North America. Lorinseria has often been lumped into the Eurasian (mainly e. Asian) Woodwardia, but is basal to Anchistea + Woodwardia, morphologically distinctive from both, and an ancient independent lineage.
Genus Identification: Identification notes: In sterile leaf, Lorinseria areolata is sometimes confused with Onoclea sensibilis, but Lorinseria has the pinnae generally alternate (vs. tending to be opposite), the pinnae generally acute or acuminate (vs. obtuse), and the pinna margin finely serrulate (vs. entire).
