Zhang Raoting and Fu Huijuan(Department of Biology, Xiamen University, Xiamen, 361005)
There are 116 species of coastal higher plants along either sides of Taiwan Strait, 99species in the east coast and 92 species in the west coast, of which the similarity coeffient accounting for 78. 5 %. On the basis of the varous coast substrata four ecologlcal groups maybe divided: sand plant, saline plant, rock and coastal forest plant, and eurylope plant. Thenorthest distribution line of tropical coastal plants such as Brugulera gymnorhiza,Excoecaria agallocha, Pandanus tectorius may be on the south of Xiamen. The flora ofcoastal plants in the Taiwan Stralt are closely relative to that in Japan and India. The tropical and subtropical floral elements are dominanting, the temperate floral element comparatively less, accounting for 89. 9% and 10. 1 % of the total number of genera. The tropical andsubtropical floral elements in the Taiwan Strait decrease gradually from south to north.
