Sua distribui??o ? pantropical com grande frequ?ncia em ambientes sazonalmente secos. Seus representantes apresentam h?bito arb?reo, arbustivo e raramente lianescente, folhas simples ou compostas 3-folioladas, br?cteas florais reduzidas e dec?duas, flores tetr?meras e noturnas com estames exsertos numerosos, ov?rio s?pero sobre um gin?foro, frutos carnosos deiscentes ou indeiscentes. Para o Brasil s?o registrados 12 g?neros e 28 esp?cies das quais 12 s?o end?micas do pa?s, ocorrendo preferencialmente em savana est?pica (strictu senso), floresta estacional semidecidual e restinga. O presente trabalho est? dividido em dois cap?tulos. O primeiro cap?tulo aborda o padr?o de distribui??o das esp?cies que ocorrem no semi?rido brasileiro e sua distribui??o intra Caatinga. Os padr?es de distribui??o foram determinados a partir da revis?o da distribui??o das esp?cies em cole??es de herb?rios e complementados com dados obtidos de bibliografia espec?fica da fam?lia. Foram avaliadas a riqueza, esfor?o de coleta e similaridade flor?stica das esp?cies intra Caatinga pelo m?todo de quadr?culas de 1 ? 1 grau. Seis g?neros e oito esp?cies foram registradas na Caatinga, sendo quatro end?micas do Brasil, dessas, apenas uma ? end?mica da Caatinga, e quatro apresentaram distribui??o neotropical. Quatro padr?es foram observados: restrito ao NE, amplo e cont?nuo no Brasil, disjunto e neotropical. Todas as esp?cies foram registradas na Bahia, estado que apresentou a maior riqueza de esp?cies por quadr?cula e tamb?m not?vel esfor?o amostral das esp?cies da fam?lia. O estado do Piau? apresenta ?reas priorit?rias para futuras coletas de Capparaceae, devido a pouca representatividade da fam?lia no estado. A an?lise de similaridade flor?stica intra Caatinga mostrou-se baixa, 22%, provavelmente devido a poucas esp?cies da fam?lia na regi?o e a ampla distribui??o das mesmas. No segundo cap?tulo ? apresentada a flora de Capparaceae para o Rio Grande do Norte (RN), visto que o estado possui uma flora pouco conhecida, com estudos pontuais. Atrav?s de coletas no estado e revis?o de herb?rio foram registrados cinco g?neros e seis esp?cies de Capparaceae no RN: Capparidastrum (1); Crateva (1); Cynophalla (2); Mesocapparis (1) e Neocalyptrocalyx (1). Capparidastrum frondosum e Mesocapparis lineata s?o novas ocorr?ncias para o estado. S?o apresentadas uma chave de identifica??o, descri??es e imagens, coment?rios sobre a biologia das esp?cies e Unidades de Conserva??o onde ocorrem. / Capparaceae comprises 25 genera and 480 species, of which 110 are included in 18 genera in Neotropics. Its distribution is pantropical with high frequency in seasonally dry environments. Its representatives are woody, shrubs and rarely wines, with simple leave or compound 3-foliolate, shorts and deciduous floral bracts, tetramerous and nocturnal flowers with exserts and numerous stamens, ovary supero on a gynophore and fleshy fruits, dehiscents or indehiscentes. For Brazil, 12 genera and 28 species are recorded and 12 of that are endemic to the country, occurring preferentially in vegetation of savanna est?pica s.str., seasonal semideciduos forest and restinga. This work shows two chapters. In the first chapter, the distributions patterns of the species occurring in the brazilian semi-arid region and their distribution intra Caatinga are discussed. The distribution patterns were determined from a review of the distribution of species in herbaria collections and supplemented with data obtained from specific bibliography about the family. A map containing 1 ? 1 grid cells was used to evaluate the richness, collection efforts and floristic similarity of the species intra Caatinga. Six genera and eight species were registered in Caatinga. Four species are endemic to Brazil, with only one endemic to Caatinga, and the other four are widespread in Neotropics. Four distribution patterns were observed: restricted to the NE, broad and continuous in Brazil, disjunct and neotropical. All the species were recorded in Bahia, state with the highest species richness per grid cell and also remarkable sampling efforts species of the family. The state of Piau? presents priority areas for further collection of Capparaceae, due to low family representation in the state. The floristic similarity analysis intra Caatinga was low, 22 %, probably due to a few species of the family in the region and the wide distribution of the same. The second chapter presents the Capparaceae of flora to Rio Grande do Norte (RN), since the state has a little-known flora, with specific studies. Through collections in the state and herbaria review, five genera and six species of Capparaceae were recorded in RN: Capparidastrum (1 spp.); Crateva (1 spp.); Cynophalla (2 spp.); Mesocapparis (1 spp.) and Neocalyptrocalyx (1 spp.). Capparidastrum frondosum and Mesocapparis lineata are new records for the state. An identification key, descriptions and images, comments on the biology of the species and protected areas where they occur are showed.
