Dryopteris cristata (Linnaeus) A. Gray. Common name: Crested Woodfern. Phenology: Jul-Sep. Habitat: Bogs, swamp forests. Distribution: Circumboreal, in North America from NL (Newfoundland) to s. SK and se. BC, south to NC, TN, OH, IN, n. IL, IA, NE, and ID; disjunct in c. GA.

Origin/Endemic status: Native

Taxonomy Comments: This species is a fertile allotetraploid derived from hybridization of D. ludoviciana and "D. semicristata", a hypothetical species which may be extinct. Its chromosome complement is symbolized LLSS. It has also served as a "parent species" of D. clintoniana, a fertile allohexaploid derived from D. cristata × goldiana. Thus, its genome constitutes two thirds of the genome of D. clintoniana.
