Endemic plants are native plants that grow in limited places. The population of an endemic species generally decreases or is maintained as a small group because an endemic species is either a remnant species that was once widely distribut- ed but became con ned to small areas due to en- vironmental factors, or a new species created by
regional speciation. Of 4,171 native plant species based on 2015 Korean Plant Names Index, 328 are endemic species, accounting for 7.8% of the total native plant species.
Among Korean endemic plant species, there are 6 species that show distinctive taxonom- ic and morphological differences compared
to other plant species. Those are Miseonnamu (Abeliophyllum distichum) found in Jincheon of Chungcheongbuk-do, Korean necklace pod (Echinosophora koreensis) found in Bukcheong of Hamgyeongbuk-do, Geumgangchorongkkot (Hanabusaya asiatica) and Korean pentactina (Pentactina rupicola) found in Geumgangsan,
Modemipul (Megaleranthis saniculifolia) found in Jirisan, and Jejugosarisam (Mankyua che- juense) found in Jejudo. They hold a high plant resource value because each plant species is the only species of its genus.
