The new species Sauvagesia insolita (Ochnaceae) is described and illustrated from campo rupestre vegetation of Sete Passagens State Park, in the northeastern most portion of the Espinhaco Range in Bahia, Brazil. Sauvagesia insolita is morphologically similar to the recently described S. paganuccii, for which we also provide an emended description. These species share an unusual floral polymorphism, where some flowers of the same individual bear free, filamentous staminodes external to the corona-like fused staminodal whorl, which is a feature newly reported for Salvagesia subsect. Vellozianae. They differ mainly by the shape and size of the leaves and the number of flowers per inflorescence.
