The '''staff vines''', also known as '''staff trees''' or '''bittersweet''', genus '''''Celastrus''''', comprise about 30 species of [[shrub]]s and [[vine]]s. They have a wide distribution in eastern [[Asia]], [[Australasia]], [[Africa]] and [[the Americas]].

The leaves are alternate and simple ovoid, typically 5-20 cm long. The flowers are small, white, pink or greenish, and borne in long panicles; the fruit is a red three-valved berry. The fruit are eaten by frugivorous [[bird]]s, which disperse the seeds in their droppings. All parts of the plants are [[poisonous]] to [[human]]s if eaten.

In [[North America]], they are known as '''bittersweet''', presumably a result of confusion with the unrelated [[Solanum dulcamara|Bittersweet]] (''Solanum dulcamara'') by early colonists. ''C. orbiculatus'' is a serious [[invasive species|invasive]] [[weed]] in much of eastern North America.
