Taxonomy

The plant previously called D. opposita is now considered to be the same species as D. oppositifolia.^[1] However Dioscorea polystachya is often incorrectly called Dioscorea opposita as well. Botanical works that point out that error may list, e.g., Dioscorea opposita auct. non Thunb. as a synonym of D. polystachya.^[7]
