The Endemic Flora of Jeju Island, Korea.

Jeju Island is a volcanic island that covers an area of 1,848 km2 and lies in southwestern sea of Korean peninsular and the north of East China Sea. Halla-san Mountain, 1,950m high, dominated in center of the Island. It has been a most interesting research site for plants because of its richness and unique biogeography. It is reported that 160 families, 668 genera and 1708 taxa (including 142 infra-species taxa) of native plants except naturalized plants. The endemic plants hold 5.3% that make up 57 families 71 genera and 90 taxa including 2 infra-species. The families having large numbers of endemic plants are Compositae (14 spp.), Rosaceae (11 spp.), Scrophulariaceae (6 spp.), Laviatae (5 spp.) and Orchidaceae, Urticaceae, Leguminosae and Umbelliferae include 3 species respectively. Sorting by genus, Prunus (6 spp.), Aster (6 spp.), Rubus (4 spp.) and Boehmeria (3 spp.) are in order. Endemic plants are diverse on the families and genera. According to life forms, Hemicryptophytes (25 spp.) and Geophytes (20 spp.) occupy 50% of all life forms. Although either the numbers or size of populations is small, only few of endemic plants are listed on Red Data Book. In order to protect the endemic plant resources from the global warming and urbanization, conservation efforts are required.
