The vascular flora was inventoried of the Cagarras Islands Natural Monument (CINM) located offshore of Rio de Janeiro, Brazil, and a total of 171 species were encountered. The families with the greatest richnesses were: Asteraceae (12 spp.), Myrtaceae (12), Fabaceae (11), Bromeliaceae (7), Cactaceae (6), Euphorbiaceae (6), and Poaceae (6). The regional vegetation was similar to restinga, although high concentrations of guano from nesting marine birds affected diversity on two islands. The threatened species Gymanthes nervosa Müll. Arg. was recorded from the municipality of Rio de Janeiro for the first time since the 1940s.
