Genera about 17, several of them comprising the characteristic mangrove vegetation mainly throughout the paleotropic regions of the world. Previously there were 4 genera in Taiwan, but now Bruguiera gymnorrhiza (L.) Lam. and Ceriops tagal (Perr.) C.B. Robinson can not be found any more in Kaohsiung.
