Abstract
This study consists of a floristic inventory of the species of Bignonieae (Bignoniaceae) recorded for the Itatiaia National Park, Rio de Janeiro, Brazil. The tribe is represented in the region by 12 genera and 18 species: Fridericia (4 spp.), Adenocalymma (2 spp.), Anemopaegma (2 spp.), Dolichandra (2 spp.), Amphilophium (1 sp.), Bignonia (1 sp.), Callichlamys (1 sp.), Lundia (1 sp.), Mansoa (1 sp.), Pleonotoma (1 sp.), Pyrostegia (1 sp.), and Xylophragma (1 sp.). We present keys for the identification of genera and species, descriptions, taxonomic comments and illustrations. Four species are recorded for region for the first time, i.e., Anemopaegma prostratum, Callichlamys latifolia, Dolichandra unguiculata, and Pleonotoma tetraquetra. We compare the floristic similarity among the Bignonieae from the Itatiaia National Park and surrounding areas using Jaccard’s coefficient of similarity and a clustering analysis based on an UPGMA algorithm. The flora of Bignonieae from Itatiaia is more similar to areas of the Atlantic rainforest, such as Picinguaba and Rio Doce, than to areas of Cerrado, as the Serra do Cipó and Grão Mogol. These results suggest that vegetation type is more important than geographic proximity in the composition of the Bignonieae from Itatiaia.
