| Note |
Some authors may argue that Dryopteris nipponensis Koidzumi is a synonym of Dryopteris erythrosora (D. C. Eaton) Kuntze. However, based on obvious difference in surface and edge of leaflets as well as sporangia, Dryopteris nipponensis Koidzumi is thought to be a different species from Dryopteris erythrosora (D. C. Eaton) Kuntze by most Japanese authors. |
