On the basis of phytogeographic evidence it is suggested that Psophocarpus tetragonolobus has an African ancestry, a possible parallel with the origin of guar (Cyamopsis tetragonoloba) is suggested. The most probable ancestral species is Ps. grand$orus native to East Africa from Ethiopia to Zaire. This hypothesis could be tested by experimental hybridization between the cultigen and its closest wild relative Ps. grand$orus.
