The Itatiaia National Park, with an area of c. 30.000 ha, is located in the Serra da Mantiqueira Range (22º19' e 22º45'S; 44º15' e 44º50'W) in the states of Rio de Janeiro and Minas Gerais. The present work is a taxonomic treatment of 29 species of Leguminosae, subfamilies Caesalpinioideae and Mimosoideae, present in the forests of the National Park. The methodology included a literature survey, field trips and study of herbarium material. Eight genera and 15 species of Caesalpinioideae and seven genera and 14 species of Mimosoideae were recorded. A key to the species, descriptions, and illustrations are presented, and information about the phenology, geographical distribution and habitats is also included.
