Pterodon is a genus of flowering plants in the legume family, Fabaceae. It includes four species of trees native to Brazil and Bolivia. Typical habitats include seasonally-dry tropical forest, woodland (cerrado), and thorn shrubland (caatinga), often on rocky outcrops.[1] It belongs to the subfamily Faboideae.
