A germplasm expedition was organized to collect seeds in the Republic of South Africa. There was an abundance of wild cucurbits there in 1996 because of an unusually rainy summer. Southern Africa is a major center of diversity for melons of Cucumis and Citrullus, and there were many plants with mature fruits along roadsides, and in other areas that had been recently disturbed. The team met in Johannesburg on 25 Apr. 1996, and covered 4213 km (passing through 35 cities and towns) located in four provinces in the northern half of the country. The expedition passed through Pretoria, Potgietersrus, Elisras, Zeerust, Bray, Van Zylsrus, Kalahari Gemsbok Nat. Park, Upington, Postmasburg, Vryburg, and Derdepoort, and visited areas bordering Zimbabwe, Botswana, and Namibia. In 9 days, 112 accessions were collected belonging to 10 species of six genera (Acanthosicyos, Citrullus, Coccinia, Cucumis, Momordica, and Zehneria). Plant, soil and geographic data were recorded for each accession. Data and seeds for the 112 accessions were added to the germplasm collections of the two countries, and can be obtained free from the USDA by interested researchers.
