Dioscorea polystachya is native to eastern Asia, where it is cultivated for its edible tubers. In North America, it is planted as a garden ornamental and has become naturalized throughout much of the eastern United States.
Only one pistillate specimen was encountered from the flora area, the plants apparently propagating vegetatively.
Dioscorea polystachya is the earliest published name for this species. The name D. oppositifolia Linnaeus, which has been misapplied to this species, actually refers to an ovate-leaved species that is native to the Indian Subcontinent and is not found in the flora area. For a more detailed nomenclatural history of D. polystachya, see Ting C. T. and M. G. Gilbert (2000).
