Oriental bittersweet has scientific name celastrus orbiculatus. It is a woody vine in the family celastraceae.
This tree is also commonly referred to as Chinese bittersweet, as well as Asian bittersweet, round-leaved bittersweet, and Asiatic bittersweet.
It is native to China and is the most widespread species of celastrus in Japan and Korea.
