Note:
this study found evidence for the probable origin of
Dioscorea rotundata
"through the direct domestication of either one or several wild species" of sect. Enantiophyllum; it also proposed the application of this name to include cultivars currently recognized in
D. cayenensis
, and the latter be a variety or subspecies of
D. rotundata
as "
D. rotundata
var. × '
