Discussion
Deparia petersenii belongs to sect. Athyriopsis. It is an edible fern native to southeastern Asia, and it persists or escapes from cultivation in southeastern North America (C. V. Morton and R. K. Godfrey 1958) but does not seem to be truly naturalized (O. Lakela and R. W. Long 1976).
Specimens of D. petersenii from North America are often misidentified as the Asian species, Deparia japonica (Thunberg) M. Kato [Diplazium japonicum (Thunberg) Beddome].
Selected References
None.
