Two new species of Mimosa sect. Batocaulon ser. Leiocarpae are described from northeastern Brazil. Mimosa cardosoi occurs in the seasonally dry woodlands known as Caatinga from the upland areas of central Bahia state. It is close to M. mensicola from which differs by leaves with smaller and more numerous leaflets and by the shape of the leaflets, calyx, and corolla. Mimosa simonii is known only from the Araripe plateau along the Ceará-Pernambuco states border. It is similar to M. verrucosa from which it differs by spiculate leaves, larger leaflets, and corolla stellate-pubescent over its entire length.
