Celastraceae

 

a family of dicotyledonous plants consisting of evergreen or deciduous trees, shrubs, and vines. The leaves are simple with small stipules. The flowers, which are usually plain, are regular, more often bisexual than unisexual, and more often in racemes than solitary. There are four or five sepals and petals and either the same number of stamens or eight to ten stamens. There is a well-developed nectarous disk inside the flower. The ovaries are either superior, or, less frequently, semi-inferior. The fruits are pod, berry, samara, or drupe, and the seeds are usually supplied with a fleshly caruncle (aril). The caruncles are often brightly colored; their coloring promotes their distribution by birds. There are about 60 genera and 850 species in countries with tropical, subtropical, and temperate climates in both hemispheres, more in southern Asia and southern Africa than elsewhere. In the USSR there are three genera— Euonymus, Kalonymus, and Celastrus—comprising 19 species; the species of the last two genera are found mainly in the Far East.
