Abstract
This paper presents the floristic composition of a sedge- swamp located in Morada do Sol, Vila Velha, Espirito Santo. Samples were collected through random walks, these being fertile branches of angiosperms and ferns. We recorded 125 species in 56 families. The Asteraceae family showed highest species richness with 13 species, followed by Cyperaceae with 12, Fabaceae 9, Rubiaceae and Poaceae with 8 and 7 species respectively. Melanopsidium nigrum Colla is on the official list of endangered species and 29 other species are first citations for the salt marsh vegetation of Espirito Santo. The presence of 28 invasive species is due to changes caused by the decrease in the flooded area by intentional landfill and burning at short intervals, which promote floristic and physiognomic changes in the ecosystem.
Key words:
richness; conservation; macrophytes; sandy coastal plains
