This work consists of the floristic survey of the Bignoniaceae in Itacolomi State Park (PEI), Minas Gerais, Brazil. The geografic distribution of species was related and the similarit between PEI and another areas of the Brazil was compared. The collection was carried out monthly in the 15 tracks, seven in the Campos Rupetres and eigth in Seasonal Forest, (N=15 expeditions), from August/2006 to Octuber/2007. The collections was preserved and included in the collection of the VIC Herbarium of the Departamento de Biologia Vegetal at Universidade Federal de Viçosa. Taxonomic determination, geografic distribution and habitat preference was carried out by specialized literature and visits to herbarios. The similaric floristic was carried out by comparison of species of the Bignoniaceae occurings in tracks at PEI and surveys to bring into another areas of the Brazil. 55 species grouped into 28 genus and 2 tribes, with 43 climber and 12 trees. The genus Arrabidaea was the most important with 10 species, Adenocalymma (6 spp.), Anemopaegma (5 spp.), Jacaranda and Handroanthus (4 spp. each), Lundia, Pleonotoma and Stizophyllum (2 spp. each), Pithecoctenium, Distictella, Amphilophium, Clytostoma, Mussatia, Callichlamys, Cuspidaria, Melloa, Parabignonia, Macfadyena, Fridericia, Manaosella, Mansoa, Pyrostegia, Tynanthus, Xylophragma, Cybistax, Sparattosperma, Tabebuia and Zeyheria one specie each. The PEI is similar to Serra do Cipo, Minas Gerais, Brazil (0,354). The common species was: Anemopaegma arvense (Vell.) Stellf. ex. de Souza, A. chamberlaynii (Sims) Bureau & K. Schum, Arrabidaea brachypoda (DC.) Bureau, A. pulchella (Cham.) Bureau, A. samydoides(Cham.) Sandwith, A. triplinervia (Mart. ex DC.) Baill. ex Bureau, Cuspidaria floribunda (DC.) A.H. Gentry, Cybistax antisyphilitica (Mart.) Mart., Distictella elongata (Vahl.) Urb., Fridericia speciosa Mart., Handroanthus albus (Cham.) Mattos, H. vellosoi (Toledo) Mattos, Pyrostegia venusta (Ker Gawl.) Miers e Zeyheria montana Mart. The species Jacaranda montana Morawetz was related to Minas Gerais, Brazil for the first time; Adenocalymma magnoalatum Scudeller is boundary to Seasonal Forest in Rio Doce State Park, but its distribution was enlarged to PEI. The most species of Bignoniaceae at PEI presented the geografic pattern distribution South America (35%), another patterns presented Neotropical (21%), Southwest Atlantic Brazil (16%), Brazil (8%), Centro-West- North-east-Southwest-South Brazil (6%), North-east- Southwest-South Atlantic Brazil (8%), Brazil Atlantic Northeast-Southwest (4%) and Anfiatlantic (2%).
