a family of dicotyledonous plants. They are shrubs (occasionally vines), more rarely small trees, semishrubs, or herbs. The leaves are usually opposite, sometimes grown together at the bases. The flowers are usually bisexual, either regular or, more frequently, more or less irregular, in cymose inflorescences that are occasionally reduced to a single blossom. The calyx and corolla are pentamerous. There are generally five stamens, but at times fewer. As a rule, the ovary is inferior. The fruit is drupaceous or berry-like, more rarely a capsule. There are 15 or 16 genera (about 400 species), largely in temperate zones of the northern hemisphere. In the USSR there are seven genera (more than 75 species); the most common are Lonicera, Sambucus, Viburnum, Abelia, Symphoricarpos, Weigela, and Diervilla. Many Caprifoliaceae are valuable decorative plants, and some are utilized in medicine.
