Dryopteris marginalis is an eastern North America endemic. Even though this species hybridizes with 10 other species, and some of these hybrids are fairly common, D . marginalis is not known to be involved in the formation of any fertile polyploid. Hybrids can be detected by malformed spores and the nearly marginal sorus position.
