Abstract

In tropical forests, climbing plants are an important component of the species richness. This study aimed to know the floristic composition of vines in a stretch of forest in the Planalto da Ibiapaba. It was performed at Sítio Coqueiros, Ipu, Ceará State, Brazil, in an area that covers about 124 ha and has an altitude between 670-850 meters. We list 61 species of vines, distributed in 43 genera and 22 families. The richest families were Convolvulaceae (11 spp.) and Fabaceae (11), followed by Bignoniaceae (seven), Passifloraceae (four), Cucurbitaceae (three) and Sapindaceae (three). We identified 31 woody vines (lianas) and 30 herbaceous vines. The volubile ascension mechanism was highlighted, being found in 55,7% of the species. An identification key for the set of identified species is displayed.
