DIVERSIDADE FLORÍSTICA E CHAVE DE IDENTIFICAÇÃO DE TREPADEIRAS EM UMA FLORESTA ESTACIONAL SEMIDECIDUAL EM PARNAMIRIM - RN, BRASIL

Abstract

Studies on the floristic diversity including climbers and also research directed to survey of these species are rare in Northeastern Brazil. With the aim of contributing to the knowledge of this component in the Northeast region and provide data on the flora of Rio Grande do Norte, a floristic study was carried out in a fragment of the Semideciduous Seasonal Forest in the municipality of Parnamirim and an identification key was created for the species. 20 species were registered belonging to 19 genera and 11 families. Eight of these species are new records for the state. The richest families in species were Fabaceae (05), Dilleniaceae (03), Bignoniaceae (02), Convolvulaceae (02) and Passifloraceae (02). The sum of the representatives of these families corresponded to 60% of the total number of species recorded. Comparative analysis suggests that studies be conducted focusing the diversity of climbing in northeastern Brazil, especially because these indicate the state of conservation of forests.
