Abstract
The research had as objective to carry out taxonomic treatment of the subfamily Papilionoideae (Fabaceae) for a fragment of Cerrado in Northeast of Brazil. For the knowledge of the plant species, were carried monthly in a field in a period from September 2016 to February 2017. The botanical material was collected at the reproductive stage and identified by comparison with type material, specialised bibliography, virtual herbarium and taxonomic keys. Were found 21 species, distributed in 14 genera. The study presents a description, geographic distribution and phytogeographical domain for each species and key identification of the taxa. The species listed have a wide geographic distribution in Brazil, occurring in several phytogeographic domains. Thus, the research contributed to the knowledge of the species of Fabaceae, which can be used in other scientific areas, as well as, help in the elaboration of the management plan and the knowledge on the conservation status of the species.
