Abstract
The Baturité mountain range is one of the largest remnants of Atlantic forest located in the the Brazilian semi-arid region. The area presents a high diversity, being considered of extreme biological importance for the conservation. The species of family Leguminosae were collected from February/2007 to February/2009 and the species list was complemented with herbarium analysis. The Leguminosae was represented by 56 genera and 132 taxa. The subfamily Papilionoideae contributed with higher richness of genus and species (31 genera and 58 taxa) followed by Mimosoideae (17 genera and 41 taxa) and Caesalpinioideae (eight genera and 33 taxa). Among the species studied in the area, 55% of them are trees and shrubs. The most diverse genera are Mimosa L. (15), Senna Mill. (12), Desmodium Desv. (seven) e Chamaecrista Moench, Bauhinia L., Inga Mill. and Aeschynomene L. (six each).
