Previous issue date: 2013-03-25 / Leguminosae is the third largest family of angiosperms with about 19.325 species and 727 genera, and it is pantropically distributed. Papilionoideae is the most diverse of the three legume subfamilies, with around 13.800 species (71%), 478 genera, and 28 tribes. Papilionoid legumes include herbs, shrubs, lianas or trees with pinnate, trifoliolate, unifoliolate or simple leaves, flowers frequently papilionate with descending imbricate petal aestivation, the petals highly differentiated into standard, keel, and wings, androecium usually diplostemous, and seeds without pleurogram, with conspicuous hilum, and the embryo radicle usually curved. The current study aims to carry out a taxonomic account of the Papilionoideae from Atlantic Forest remnants in Rio Grande do Norte, Brazil, across the herbaria data surveys, collections of field samples and morphological analysis of the collected specimens and/or herbaria materials. Identification key, descriptions, diagnostic characters, illustrations, and geographic distribution of the 68 species and 32 genera within the following tribes Phaseoleae (11 genera/24 species), Dalbergieae (9/20), Swartzieae (3/3), Millettieae (2/4), Sophoreae (2/2), Abreae (1/1), Crotalarieae (1/3), Desmodieae (1/7), Indigofereae (1/3), and Sesbanieae (1/1). The most species-rich genera were Desmodium Desv. (7 species), Centrosema (DC.) Benth. (5), Stylosanthes Sw. (5), Aeschynomene L. (4) and Macroptilium (Benth.) Urb. (4). Concerning to the habit, the herbaceous and shrubby has predominated with 60% (41 spp.), following by the vine and lianas with 28% (19 spp.) and the woody with only 12% (8 spp.). Thirty two species and the following genera are newly recorded for the flora of Rio Grande do Norte: Chaetocalyx, Cochliasanthus, Crotalaria, Galactia, Geoffroea, Macroptilium, Rhynchosia, Swartzia, Trischidium, and Vigna / Leguminosae ? a terceira maior fam?lia de angiospermas, apresentando cerca de 19.325 esp?cies e 727 g?neros e distribui??o pantropical. Papilionoideae ? a mais diversa das tr?s subfam?lias de leguminosas, com cerca de 13.800 esp?cies (71%) subordinadas a 478 g?neros e 28 tribos. ? caracterizada pelo h?bito herb?ceo, arbustivo, lianescente ou arb?reo, folhas pinadas, trifolioladas, unifolioladas ou simples, flores frequentemente papilionadas, com as p?talas diferenciadas em estandarte, carena e alas em preflora??o imbricativa descendente ou vexilar, androceu geralmente diplost?mones e sementes sem pleurograma, com hilo bem desenvolvido e embri?o com rad?cula geralmente curvada. O presente estudo teve como objetivo realizar um estudo taxon?mico das Papilionoideae ocorrentes na Mata Atl?ntica do Rio Grande do Norte, Brasil atrav?s do levantamento de dados de herb?rios, coletas de materiais em campo e an?lise morfol?gica dos esp?cimes coletados e/ou depositados em herb?rios. S?o apresentadas chave de identifica??o, descri??es, caracteres diagn?sticos, ilustra??es e distribui??o geogr?fica das 68 esp?cies e 32 g?neros distribu?dos nas tribos Phaseoleae (11 g?neros/24 esp?cies), Dalbergieae (9/20), Swartzieae (3/3), Millettieae (2/4), Sophoreae (2/2), Abreae (1/1), Crotalarieae (1/3), Desmodieae (1/7), Indigofereae (1/3) e Sesbanieae (1/1). Os g?neros mais representativos foram Desmodium Desv. (7 esp?cies), Centrosema (DC.) Benth. (5), Stylosanthes Sw. (5), Aeschynomene L. (4) e Macroptilium (Benth.) Urb. (4). Quanto ao h?bito, predominou o herb?ceo e arbustivo com 60% (41 spp.), seguido do trepador e lianescente com 28% (19 spp.) e o arb?reo com apenas 12% (8 spp.). Neste trabalho, 32 esp?cies e os seguintes g?neros s?o registrados pela primeira vez para a flora do Rio Grande do Norte: Chaetocalyx, Cochliasanthus, Crotalaria, Galactia, Geoffroea, Macroptilium, Rhynchosia, Swartzia, Trischidium e Vigna
