A perennial vine in the Dioscoreaceae family (APG classification: Dioscoreaceae). A cultivated variety of bitter yam. Native to China, it is cultivated in tropical Asia. Only female plants were introduced to Japan and are cultivated there, but as there are no male plants, they do not bear fruit even after flowering. The tubers grow underground, with a dark brown surface and a yellowish-white interior, and many fibrous roots. Large bulbils measuring about 2 cm in diameter grow in the leaf axils. Both the tubers and bulbils can be cut into small pieces and eaten boiled, simmered, or steamed, giving them a chestnut-like flavor.
