Resumo
We analyzed the fl oristics and phytosociology of three palm swamps in the municipality of Bela Vista de Goiás,
located in the state of Goiás, Brazil, in the central part of the Brazilian savanna (Cerrado). Th e fl oristic surveys were
conducted monthly from May 2008 to April 2009, and 310 species were recorded (seven bryophytes, 15 ferns and 288
angiosperms). Bryophytes belonged to fi ve genera and fi ve families; ferns belonged to nine genera and nine families;
and angiosperms belonged to 134 genera and 45 families. Th e angiosperm families with the highest species richness
were Poaceae, Cyperaceae, Asteraceae, Eriocaulaceae, Xyridaceae, Lentibulariaceae, Melastomataceae, Rubiaceae and
Fabaceae. Th e palm swamps were divided into three zones of increasing humidity: edge, middle and core. Th e number
of species was higher in the middle than at the edge and the core. Th e families with the highest cover values were
Cyperaceae, Melastomataceae, Arecaceae and Poaceae. Although the palm swamps had been disturbed to varying
degrees, those disturbances did not aff ect the fl ora in the middle or the core. Floristic similarity was high between
these two zones within a given palm swamp and low between the edges of diff erent palm swamps.
