box

In botany, an evergreen shrub or small tree (genus Buxus) of the box family (Buxaceae), best known for the ornamental and useful boxwoods. The family comprises seven genera of trees, shrubs, and herbaceous plants, native to North America, Europe, North Africa, and Asia. The plants bear male and female flowers, without petals, on separate plants. The leathery, evergreen leaves are simple and alternate. Fruits are one- or two-seeded capsules or drupes. Three species of the genus Buxus provide the widely grown boxwood: the common, or English, box (B. sempervirens), used for hedges, borders, and topiary figures; the Japanese box (B. microphylla); and the tall boxwood tree (B. balearica).
