Thus, we sought to characterize the frequency of sexual systems from species recorded in seed rain occurring in a tropical rainforest (Atlantic Forest) in Caparaó National Park, Espírito Santo State, Brazil. We collected the seed rain for twelve months, classified and recorded the species for: sexual system; pollination and dispersion syndrome; and fruit type. Then we measured the correlation between these attributes through correspondence analysis. Regarding sexual systems, 71% were hermaphrodites, 13% dioecious, and 11% monoecious. Hermaphrodites are best associated with pollination, dispersion and fruit types, represented by 65% of data variance. This study may contribute to elaborating management and conservation programs taking into account the interaction of plants with the local fauna. Keywords: seed rain, reproductive ecology, woody layer, Caparaó National Park, Atlantic Forest.
