NAKANISHI, Hiroki. (477-53,Ohte-machi, Nagasaki City). 1985. Geobotanical and ecological studies on three semi-mangrove plants in Japan. Jap. J. Ecol., 35 : 85-92. The three semi-mangrove plants ; Myoporum bontioides, Hibiscus hamabo and Paliurus ramosissimus were studied-geobotanically and ecologically. Distribution maps showing both the locality and size of communities dominated by the three species respectively were drawn. These species grow luxuriantly throughout the northernmost part of their distribution areas. The structure of disseminules and tests of buoyancy and viability in salt water proved that these species could disperse by sea currents. The species compositions and habitats of these communities were described. The Myoporum bontioides community is described as the new association Myoporetum bontioidetis which is usually monospecific. The association Hibiscetum is composed of only Hibiscus hamabo in the shrub layer and occasionally with some halophytes in the herb layer. The Paliurus ramosissimus community is invaded by many non-halophilous herbs. These semi-mangrove communities occur far more widely than the distribution areas of mangrove.
