Newtonia is a genus of flowering plants in the legume family, Fabaceae. It includes 16 species of trees native to sub-Saharan Africa.[1] It belongs to subfamily Caesalpinioideae[2] and the Mimosoid clade[2] or tribe. The genus is known from the early Miocene (21.73 Ma) of Ethiopia based on compressions of its diagnostic, winged seeds. [3]
