The work consists of the taxonomic and etnobotamical study of Leguminosae in forest fragments and agroforest systems (AFSs) in the Municipality of Araponga, Minas Gerais. The diversity of Leguminosae that occur in two forest fragments and in seven (AFSs) locatede around the Parque Estadual da Serra do Brigadeiro (PESB) is presented, with etnobotanical information about the interaction of the neighborhood with the florestical diversity of these areas. The botanical collects aiming at the floristical study in the forest fragments and in the AFSs occurered during monthly trips, from August, 2005 to September, 2006, during walkings around and in the interior areas. The material collected were herborized according to usual techniques and included to the collection of the herbarium VIC of the Vegetal Biology Departament of the Federal University of Viçosa. The identification concerning the species were made with specific literature and information gotten from specialists on the subject. The etnobotanical information were obtained from August, 2005 to December, 2006, through healf-structured interviews with 21 people living in Araponga. Ninety species of Leguminosae were identified, belonging to 52 genera, 85 species native of Brazil. In the forest fragments of the taxonomic study, 48 species were identified, predominating the genera Machaerium Pers. (s spp), Inga Mill. and Senna Mill., (4spp each). Leguminosae is well represented in the fragments located around the Parque Estadual da Serra do Brigadeiro (PESB), Minas Gerais where rare species like Camptosema bellum, strictly living in the humid mountains of Minas Gerais and in same parts of the Espírito Santo State; and Dalbergia nigra which is under risk of extinction. In the AFSs, 61 species belonging to 39 genera were identified outstanding Senna Mill., with six species. The seven AFSs presented low florestical silirity, reaching only 0.48 of the sorensen scale. Among 90 species identified in forests and systems, 58 presented potential of use: 37 in forest areas and 38 in AFSs. Eleven possiblilities of use were detected, eight of them only in the fragments while in the AFSs the agriculturists also detected species used as mulch, shadow of coffee trees and flowers for bees. In the fragments, 17 species were used for burning, 17 for technology, 15 for fences and 14 for buildings. On the other hand, in the AFSs, 18 species were used as fertilizer followed by 14 species which were used as food for people and animals. Considering all the species in the several environments researched, fertilizer and firewood were the most commonly used, 21 species for each one. Among the main species used, 12 were cited by more than three informants, while in the AFSs only two were considered. Among the species with potencial of use, 34 were considered able of nodosity, 22 of them were used by the agriculturists in the AFSs. The agriculturists consider 22 as etnospecies belonging to the local fauna, wich live in the AFSs, considered as refuge areas. The etnobotanical study showed that the people involved with the research have a lot of information living in those places have lots of information about the local knowledge, so that contributing to the report of the tradicional knowledge most only of the city bul also of the state of Minas Gerais.
