Geoffroea (Leguminosae–Papilionoideae) has traditionally comprised three species. In this revision the number of species is reduced to two because G. striata (Willd.) Morong is considered indistinct from G. spinosa Jacq. and is placed in synonymy. No significant morphological variation is found between the five isolated areas of distribution of G. spinosa, which occurs in the disjunct seasonally dry tropical forests of South America, and there is certainly no basis for recognizing separate taxa.
