Buxus

Common boxwood ( Buxus sempervirens)

The boxwood (Buxus ) are a genus of flowering plants in the family of boxwood plants ( Buxaceae ).

Description

They are evergreen, small, usually well-branched shrubs and trees. The whole plant is glabrous. The against-constant leaves are simple.

Beech trees are monoecious getrenntgeschlechtig ( monoecious ). The flowers are usually together in compact inflorescences aged men. The flowers are mostly two-to fourfold. Sepals and petals are more or less the same design and therefore it looks as if only a Blütenhüllblattkreis available. Per male flower there are four or six (rarely ten) stamens. For each female flower three carpels are fused to an ovary with two ovules per ovary chamber. The female flower are three pen available. They form seed capsules with three compartments, each of which has two "horns". The seeds are shiny black.

Distribution and systematics

The beech trees are widespread with 70 species in Europe, Asia, Africa and America. Most species are native to the tropics. In Europe, only two species are found, the common boxwood ( Buxus sempervirens) and the Balearic boxwood ( Buxus Balearica ); both species have been well cultivated and wild occasionally.
