Conteúdo: | The floristic composition of campo limpo úmido, a moist savanna grassland vegetation of the cerrado biome, is still little described, even though its herbs and subshrub from a major component of the cerrado vegetation. The objective of this stydy was to characterize the floristic richness of the herbaceous and subshrub layer of moist grassland at the Água Fria Farm, Alto Paraíso, Goiás State (14°04'8.83''S, 47°30'33.1''W). The principal use of such grasslands is to graze cattle; in addition, local people collected vast numbers of selected species of wild plants to sell for the decorative dried plant trade, or for their medical qualities. Little is brown, however, about the sustainability of this extractivism. A survey of a 21 ha area, with intensive quartely collections of herbarium specimens, was made from April 2000 to March 2001. Despite  the small size of the study site in proved to be very rich floristically. A total of 207 species in 90 genera and 33 families was registered in the area. Thirty-one species not recorded in the checklist of the flora of the cerrado biome were found in the study, plus three that seem to be new to science. The richest families were Cyperaceae (30 species), Poaceae (28), Xyridaceae (23), Eriocaulaceae (20), Asteraceae (18), and Orchidaceae and Melastomataceae with 10 species each. These results suggest the need for more research on the moist grasslands to provide overall estimates for the plant species richness of the widespread vegetation type and as a basis to help guide conservation and management policies.
