Celastrus paniculatus
Also called Celastrus, Black Oil Tree, Intellect Tree
Celastrus paniculatus is a woody liana commonly known as black oil plant, climbing staff tree, and intellect tree (Sanskrit: jyotishmati ज्योतीष्मती, Hindi: mal-kangni माल-कांगनी, Chinese: deng you teng 灯油藤). This climbing shrub grows throughout India at elevations up to 1,800 m (5,900 ft).
C. paniculatus is a deciduous vine with stems up to 10 cm (3.9 in) in diameter and 6 m (20 ft) long with rough, pale brown exfoliating bark covered densely with small, elongated lenticles. The leaves are simple, broad, and oval, obovate or elliptic in shape, with toothed margins.
Celastrus paniculatus has a relative that grows in the United States that is poisonous (Celastrus orbiculatus), so identifying this plant carefully can be important.
