“…Its wide distribution reflects probable dispersal by humans (Verdcourt and Halliday 1978). In Zaire, the species is somewhat weedy and is found in damp ground near rivers, streams, lakes, ponds, and marshes and does extend to drier areas.…”

“…The extent ofvariability ofthe flowers, pods, leaves, and seeds found in the cultivated winged bean suggest that a long period of domestication has occurred in southeast Asia (Pickersgill 1980). For more information on the taxonomy of the genus refer to the revision published in 1978 (Verdcourt and Halliday 1978) and the more recent investigation of the inter-and intra-generic relationships by Maxted (Maxted 1984). Between March and August 1987 we visited Bas Zaire, Kinshasa, Kivu, and Shaba provinces within Zaire, to collect information on five of the described species of Psophoearpus occurring there (Fig.…”

In Zaire the distribution offour of the wild species in the genus Psophocarpus rangesfrom humid. evergreen. Guinea-Congolian rainforests to high altitude woodlands. dry semi-deciduous forests, and savanna. Material of Psophocarpus scandens, P. grandiflorus, P. lancifolius, P. lecomtei, and P. lancifolius (yellow-seeded form) were collectedfrom wild and naturalizedpopulations in Zaire. Various organs ofP. scandens, P. grandiflorus, and P. lancifolius are used as food sources. medicinals. and as sources oftannins. Psophocarpus lancifolius and P. lecomtei have reportedly been used as a food source and fish poison. respectively. The various organs were analyzed for carbohydrate. lipid. N. S, t, K. Mg, Ca. n« Fe. AI. 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 ofpests and diseases. and ecogeographical information are presented. Emploi, composition alimentaire et ecogeographie de quatre especes de Psophocarpus (Fabaceae, Phaseoleae) au Zaire. Au Zaire la distribution de quatre especes sauvages du genre Psophocarpus va des forets tropicales humides et chaudes des plaines de la Guinee-Congo aux bois de haute altitude. auxforets seches d'arbres caducs et a la savane. Des elements de Psophocarpus scandens, P. grandiflorus, P. lancifolius, P. lecomtei, et P. lancifolius (a semencejaune) ont ere recoltes dans la population de la brousse et des villes au Zaire. Divers organes de P. scandens, P. grandiflorus, et de P. lancifolius sont source de nourriture, de remedes medicinaux et de tannins. II a ete rapporte que le Psophocarpus lancifolius et Ie P. lecomtei sont ala fois source de nourriture et de poison de poisson. Les divers organes ont ere analyses pour leur teneur en lipids. glucides, N (proteines), S. P, K. Mg. Ca. Na, Fe. AI, Mn, B. Cu. et Zn. Chacune de ces especes pourrait devenir source de nourriture et element genetique pour ameliorer la reproduction du pois carre africain cultive. Les noms locaux, des notes phenologiques, les problemes dus aux insectes nuisibles et aux maladies. et des renseignements ecogeographiques sont aussi presentes ici. THE CULTIVATED WINGED BEAN AND ITS WILD RELATIVESThe winged bean, Psophocarpus tetragonolobus (L.) DC. (Fabaceae), is an important source of high protein human food in southeast Asia, Papua

“…It is also of some interest to note that the winged bean itself flourishes best in montane areas for example in Papua-New Guinea. VERDCOURT & HALLIDAY (1978) do point out that palynologically Ps. grandiflorus and Ps.…”

“…In view of the parallels with crops such as the cowpea (STEELE, 1976), guar (HYMOWITZ, 1972) and sorghum (DOGGETT, 1976) which have been moved by man from Africa to Asia, it is not unreasonable to suggest that the winged bean might be included in this group. Certainly little or no hard evidence has been advanced by VERDCOURT & HALLIDAY (1978), WESTPHAL (1974) or HYMOWITZ & BOYD (1977) to identify with any degree of conviction a specific centre of origin outside Africa.…”
