Bignoniaceae na RPPN do Clube Caça e Pesca Itororó, Uberlândia, Minas Gerais, Brasil

Abstract

The RPPN of the Clube Caça e Pesca Itororó de Uberlândia (CCPIU) is located 8 km west of the urban perimeter of the municipality of Uberlândia, Minas Gerais and shows a very diverse and a well preserved flora. Bignoniaceae presents ca. of 840 species organized in 82 genera in the pantropical region. Currently, Brazil has 416 species distributed in 33 genera, which makes the family particularly abundant and diverse in the country. In the Cerrado, Bignoniaceae is represented by 173 species and 28 genera. Among the eight tribes recognized for the family, Bignonieae is the one of major importance and diversity, possessing 21 genera and about 400 species originating in the tropical forests of South America about 50 million years ago. This study presents the inventory of the flora of Bignoniaceae from the RPPN of the Clube Caça e Pesca Itororó, Uberlândia, Minas Gerais. In the studied area, 20 species belonging to 10 genera, with distribution in different phytophysiognomies occur, mainly in the cerrado sensu stricto, dirty field, humid field and sidewalk, with a greater number of species occurring in the cerrado sensu stricto. Adenocalymma and Jacaranda are the most diverse genera with four species each, followed by Anemopaegma, Cuspidaria, Fridericia, Handroanthus (two spp. each), Amphilophium, Pyrostegia, Tabebuia and Zeyheria, with only one species each. In the present study, morphological descriptions of the reproductive and vegetative structures are provided, as well as identification keys for the species. In addition, occurrence, flowering and fruiting data, taxonomic comments and images of the main diagnostic characteristics of Bignoniaceae are also presented.
