Taxonomy The plant previously called D. opposita is now considered to be the same species as D. oppositifolia. However Dioscorea polystachya is often incorrectly called Dioscorea opposita. Botanical works that point out that error may list, e.g., Dioscorea opposita auct. non Thunb. as a synonym of D. polystachya.
