112 species of wetland vascular plants in Guangzhou area were recorded in an investigation, which belong to 42 families and 93 genera. Most of them are angiosperms including many species of Gramineae, Composita, Polygonum and Cyperus. Alternanthera philoxeroides (Mart.) Griseb., Solanum americanum Miller and Commelina communis Linn. are the species with higher appearance frequency. These three species were recorded in more than 70% of the investigating places. Of the 112 species recorded 15 species are hydrophytes, accounting for 13.39% of the total species, and most of them are monocot plants; 27 species are hygrophytes, accounting for 24.11%, and 70 hygrophilous species, accounting for 62.50%. Some of the species have already been widely used in wetland landscape gardens and artificial wetlands, and others have potential for future use.
