Definition

Noun: * Oriental bittersweet: A woody, perennial vine (Celastrus orbiculatus) native to East Asia, characterized by its ornamental value, particularly its showy fruit. The plant produces clusters of small, round fruits that split open when mature to reveal bright red seeds covered by a fleshy, scarlet aril (seed coating), set against a background of yellow-orange outer husks. It is considered an invasive species in North America.
