http://dx.doi.org/10.5902/198050987548 The floristic survey of tree species was performed in a ‘Restinga’ forest, municipality of Pelotas, RioGrande do sul State, Brazil. The area studied is known as ‘Mata da Praia do Totó’(‘Totó’ beach forest),and comprises a remnant formed by a sandy and turf ‘Restinga’ forest. A total 65 native species weresampled comprising 51 genera distributed in 34 families. The family with the greatest number of specieswasMyrtaceae, with ten species, followed bySalicaceaeandRubiaceae.The most representative generawereMyrsineandEugenia,respectivelly sampled with four and three species. The analysis of similaritysampled that the sandy forest is floristically related to riparian and hillside forests and the forest peat isrelated to other forests located in areas of permanent water saturation of soil. Species richness of the siteis high for ‘Restinga’ forests in Rio Grande do Sul state, probably due to the influence of forests located inSerra dos Tapes and by diversity of the environments that make up the study area.
