Buxus is a genus of about 70 species in the family Buxaceae. Common names include box or boxwood. The boxes are native to western and southern Europe, southwest, southern and eastern Asia, Africa, Madagascar, northernmost South America, Central America, Mexico and the Caribbean, with the majority of species being tropical or subtropical; only the European and some Asian species are frost-tolerant. Centres of diversity occur in Cuba, China and Madagascar. They are slow-growing evergreen shrubs and small trees, growing to 2–12 m tall. The leaves are opposite, rounded to lanceolate, and leathery; they are small in most species, typically 1.5–5 cm long and 0.3–2.5 cm broad, but up to 11 cm long and 5 cm broad in B. macrocarpa. The flowers are small and yellow-green, monoecious with both sexes present on a plant. The fruit is a small capsule 0.5–1.5 cm long, containing several small seeds. The genus splits into three genetically distinct sections, each section in a different region, with the Eurasian species in one section, the African and Madagascan species in the second, and the American species in the third. The African and American sections are genetically closer to each other than to the Eurasian section.

Uses
Cultivation
Box plants are commonly grown as hedges and for topiary. In Britain and mainland Europe, box is subject to damage from caterpillars of Cydalima perspectalis which can devastate a box hedge within a short time. This is a recently introduced species first noticed in Europe in 2007 and in the UK in 2008 but spreading. There were 3 UK reports of infestation in 2011, 20 in 2014 and 150 in the first half of 2015.
Wood carving
Owing to its fine grain it is a good wood for fine wood carving, although this is limited by the small sizes available. It is also resistant to splitting and chipping, and thus useful for decorative or storage boxes. Formerly, it was used for wooden combs. As a timber or wood for carving it is "boxwood" in all varieties of English. Owing to the relatively high density of the wood, boxwood is often used for chess pieces, unstained boxwood for the white pieces and stained boxwood for the black pieces, in lieu of ebony. The extremely fine endgrain of box makes it suitable for woodblock printing and woodcut blocks, for which it was the usual material in Europe. In the 16th century, boxwood was used to create intricate decorative carvings, including intricate rosary prayer beads. As of 2016, the largest collection of these carvings is at the Art Gallery of Ontario in Toronto. High quality wooden spoons have usually been carved from box, with beech being the usual cheaper substitute. Boxwood was once called dudgeon, and was used for the handles of dirks, and daggers, with the result that such a knife was known as a dudgeon. Although one "in high dudgeon" is indignant and enraged, and while the image of a dagger held high, ready to plunge into an enemy, has a certain appeal, lexicographers have no real evidence as to the origin of the phrase.
Musical instruments
Due to its high density, resistance to chipping, and relatively low cost, boxwood has been used to make parts for various stringed instruments since antiquity. It is mostly used to make tailpieces, chin rests and tuning pegs, but may be used for a variety of other parts as well. Other woods used for this purpose are rosewood and ebony. Boxwood was a common material for the manufacture of recorders in the eighteenth century, and a large number of mid- to high-end instruments made today are produced from one or other species of boxwood. Boxwood was once a popular wood for other woodwind instruments, and was among the traditional woods for Great Highland bagpipes before tastes turned to imported dense tropical woods such as cocuswood, ebony, and African blackwood.
