*Deparia petersenii (Kunze) M. Kato. Section: Deparia. Subsection: Athyriopsis. Japanese Lady Fern. Phen: Jun-Oct. Hab: Swamp forests, wet hammocks, moist banks, disturbed areas. Dist: Introduced and naturalized in the Southeast, including in sw. NC (K.A. Bradley, pers.comm., 2021), e. and w. SC (K.A. Bradley, pers.comm., 2021), c. and s. GA, AL, s. MS, e. LA, and FL, from a native distribution in se. Asia. See Wyatt (2020) for discussion of naturalization in our region.

ID notes:The contrast of stiff silvery hairs against a dark brown petiole (stipe) and rachis is a helpful diagnostic feature.

Origin/Endemic status: E. and se. Asia

Taxonomy Comments: Deparia petersenii as currently broadly circumscribed is a polyploid complex, likely to be interpreted in the future as including several species (Kuo et al. 2018, Shinohara et al. 2006).
