To test which of these scenarios is more likely, we surveyed patterns of genetic diversity in eight (n = 307) populations of Cyrtomium fulcatum from southern Korea.

In Korea, many ferns are characteristic of the warm-temperate and subtropical vegetation, such as Cyrtomium falcatum (L.
Cyrtomium falcatum is an evergreen homosporous fern that usually grows on coastal rocky slopes in the warmer parts of south to northeastern Asia (India, Vietnam, eastern and southern China, Taiwan, southern Korea, and Japan; Iwatsuki, 1992).
