DistributionThree collections are known from the Piedmont: Durham County, banks of a suburban creek, C.J. Rothfels in 2010; Wake County, East Fork Mine Creek Greenway, B. England in 2020; Anson County, Becky Dill in 2023. There are several populations known from Shelley Lake Park in Raleigh (Wake County).

Native of eastern Asia; in N.A. reported from AR, GA, and NC. Not known in N.A. prior to 2000.
AbundanceVery rare.
HabitatBanks of suburban creeks, as well as ravines and bluffs near creeks. For an exotic species, it tends to grow in "wild" places that make it appear to be a native species.
Phenology
IdentificationThis fern looks superficially like Marginal Wood-fern (D. marginalis), but the sori are medial on the pinnules (vs. marginal), and have a reddish cast.
