    Distribution
    Africa: Ghana, Togo, Benin, Nigeria.
    Ecology
    Dry stream bed; cultivated land; damp and shady place; alt. up to 800 m.
    Conservation
    Pseudovigna puerarioides is known from c. seven localities. Additional research in herbaria not yet visited by the authors is likely to result in a higher number of localities. The extent of occurrence is c. 100,000 km2. The species has been collected in cultivated land, and is therefore able to persist in secondary habitats. Therefore, the conservation status is here assessed as Least Concern (LC) (IUCN 2001).
