Selected specimen: — BRAZIL. Paraná: Mangueirinha , 26°09'S, 52°11'W, 18 December 2006, G. B. Ceolin 113 (ICN) .

Distribution: — Paraguay, Argentina and Brazil (BA, MG, MS, MT, PR. RS, SC, SP).

Habitat and ecology:—Cerrado biome and in higher altitude grassland of the Mata Atlantica biome in southern Brazil, growing in campos and on hillsides, at elevations of 300–1200m, on shallow rocky soils or in clay.

Notes: — Burkart (1971) described Galactia pretiosa var. trifoliolata to taxonomically differentiate the occasional individual plant with three leaflets per leaf in contrast to the typical variety with unifoliolate leaves. We do not recognise this morphotype as a distinct taxon.

Phenology:— Flowering and fruiting from October to March.
