Dioscorea oppositifolia is a type of yam (Dioscorea) native to Myanmar (Burma) and to the Indian Subcontinent (India, Sri Lanka, Bangladesh).[3][4][5][6]

Taxonomy

The plant previously called D. opposita is now considered to be the same species as D. oppositifolia.[2] 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]
