【 摘 要 】

Swamp forests are associated with hydromorphic soils and are naturally fragmented in their distribution. Several local phytosociological surveys on the woody flora of these forests have been conducted in southeastern and southern Brazil. We present here a comprehensive floristic list based on these surveys, including 77 families, 211 genera and 518 native species. The richest families were Myrtaceae (78 species), Fabaceae (47) and Lauraceae (38). The richest genera were Eugenia (24), Myrcia (24), Miconia (21) and Ocotea (20). The woody flora of these swamp forests has great heterogeneity, with most species occurring in one or few sites. Their flora is formed by a few flooding specialist or tolerant species, common in many sites, and many other species that come from the surrounding vegetation. Considering the high degree of deforestation in southeastern and southern Brazil, including swamp forests, the floristic patterns presented here can be useful for the future efforts of conservation, management and restoration of these forests.
