In an article entitled, “Genetic Diversity in the Common Terrestrial Orchid Oreorchis patens and Its Rare Congener Oreorchis coreana: Inference of Species Evolutionary History and Implications for Conservation” published in the May issue of the Journal of Heredity [103(5):692-702], Mi Yoon Chung and six other investigators  observed that  unlike the main land Oreorchis patens, the congeneric species  Ore. coreana, confined to the Korean island of Jeju lacks genetic diversity and hardly there is any variation in its morphological characteristics. Unlike Ore. patens the species in the main peninsula that occurs in  relatively stable habitats maintaining large population size, the  endemic specie Oe. coreana  need to be protected and conserved in order to save it from extinction.
