Floristic surveys were conducted at six sites of Carey Island, Malaysia. From the surveyed sites, 53 species that belong to 48 genera and 30 families had been identified. The common species recorded were Avicennia alba, A. intermedia, Bruguiera gymnorhiza, Ceriops tagal, Nypa fruticans, Rhizophora apiculata, R. mucronata, Scyphiphora hydrophyllacea, Sonneratia alba, Xylocarpus granatum and X. moluccensis. However, the dominant pteridophytes were Adiantum flabellulatum, Lygodium salicifolium and Nephrolepis biserrata. With special interest to mangrove sites, the majority of the identified species are of economic importance either as a source of food, medicine, wood, ornamentals or for coastal protection. Xylocarpus species are considered as important endangered mangrove species in Malaysia. Therefore, propagation of these species through tissue culture, as an approach for conservation, has been initiated.
