Surveys of wild yam (Dioscorea) species grown in Cameroon revealed some that had never previously been reported. Yams of the complex D. cayenensis-rotundata proved to be very numerous and were classified through enzymatic and morhological analyses. The diversity of the wild forms suitable for cultivation and the different types of selection pressure exerted account for the variability of this complex.The agricultural and economic situation of yams in Cameroonand the choice of species based on local conditions were also covered in the study.
