 note = {Distribution and ecology of Hibiscus hamabo Siebold et Zucc. (Malvaceae) and Paliurus ramosissimus (Lour.) Poiret (Rhamnaceae) which are semi-mangrove plant were investigated in Jeju Island of Korea where is the northwesternmost distribution area of these species. H. hamabo is restricted on eastern side and P. ramosissimus is on western and eastern sides of the island. Unlike in Japan, these species grow on basalt of the lava coast. H. hamabo community and P. ramosissimus community were phytosociologically studied. H. hamabo community was composed almost only by H. hamabo and was smaller in height than the one in Japan. P. ramosissimus community was constantly associated with P. ramosissimus, Maclura tricuspidata and Sageretia theezans. These species have relatively small, hard, leathery drought-resistant leaves. This community may be attributed to a new association. The fruit size, number of seeds per fruit and seed weight of H, hamabo were measured and compared with those in Japan., 長崎大学教育学部紀要. 自然科学. vol.71, p.1-10; 2004},
