Abstract
In Zaire the distribution of four of the wild species in the genusPsophocarpus ranges from humid, evergreen, Guinea-Congolian rainforests to high altitude woodlands, dry semi-deciduous forests, and savanna. Material ofPsophocarpus scandens, P. grandiflorus, P. lancifolius, P. lecomtei, andP. lancifolius (yellow-seeded form) were collected from wild and naturalized populations in Zaire. Various organs ofP. scandens, P. grandiflorus, andP. lancifolius are used as food sources, medicinals, and as sources of tannins.Psophocarpus lancifolius andP. lecomtei have reportedly been used as a food source and fish poison, respectively. The various organs were analyzed for carbohydrate, lipid, N, S, P, K, Mg, Ca, Na, Fe, Al, Mn, B, Cu, and Zn. In their own right, these species have potential for wider use as food sources and genetic material for improvement breeding with the cultivated winged bean, Local names, phenological notes, presence of pests and diseases, and ecogeographical information are presented.
