Deciduous, ± glabrous climber up to 12 m high, usually dioecious or gynodioecious. Twigs green; the outermost scales of the winter buds often transformed into sharp spines 1-2 mm long. Branches terete, greyish brown. Lvs suborbicular, obovate or elliptic, obtuse to acuminate at apex, crenate, (3)-5-10 cm long. Petiole (0.5)-1-2 cm long. Cymes 1-many-flowered, shortly pedunculate, axillary. Fls c. 4-10 mm diam. Petals pale green, narrowly oblong, separated, often reduced in ♀. Capsule globose, yellow to yellow-orange, 6-8 mm diam., exposing the scarlet aril after opening.

Much like no. 1 [Celastrus scandens L.]; lvs suborbicular to broadly oblong-obovate; fls few in small axillary cymes much shorter than the subtending lvs; 2n=46. Native of e. Asia, established as an escape in open woods and thickets here and there from Conn. s.
