Buxaceae is a small family of four or five genera and about 90-120 species of flowering plants. Plants are living Organisms belonging to the kingdom Plantae. The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group Magnoliopsida is the Botanical name for a class of Flowering plants By definition the class will include the family Magnoliaceae, but its Buxales is a Botanical name at the rank of order Under the APG II system, Buxaceae is a family unplaced as to order in the Eudicots. Barthélemy Charles Joseph Baron Dumortier (born on April 3, 1797 in Tournai; died in 1878 was a Belgian Politician and Buxus is a Genus of about 70 species in the family Buxaceae. Common names include box (majority of English-speaking countries or boxwood Pachysandra is a genus of four or five species of Evergreen Groundcovers or Subshrubs belonging to the Boxwood Family Buxaceae Sarcococca ( Sweet box) is a Genus of 16-20 species of Flowering plants in the family Buxaceae, native to eastern and southeastern UserPolbot. --> Styloceras is a genus of Plant in family Buxaceae. In Biological classification, family ( Latin The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group They are shrubs and small trees, with a cosmopolitan distribution. A shrub or Bush is a horticultural rather than strictly botanical category of Woody plant, distinguished from a Tree A tree is a perennial Woody plant. It is most often defined as a woody plant that has many secondary branches supported clear of the ground on a single main stem or In Biogeography, a Biological category of living things is said to have cosmopolitan distribution if this category can be found almost anywhere around the world A fifth genus sometimes accepted in the past (Notobuxus), has been shown by genetic studies to be included within Buxus (Balthazar et al. , 2000).
The family is recognised by most taxonomists, and is sometimes known as the box family. Buxus is a Genus of about 70 species in the family Buxaceae. Common names include box (majority of English-speaking countries or boxwood However, its placement and circumscription has varied; some taxonomists treat Styloceras in its own family Stylocerataceae, and others have included Simmondsia (usually placed in its own family Simmondsiaceae) in Buxaceae. UserPolbot. --> Styloceras is a genus of Plant in family Buxaceae. Jojoba ( Simmondsia chinensis) pronounced "hō- hō' -bə" is a Shrub native to the Sonoran and Mojave Deserts
The APG II system of 2003 recognises the family, but in a new circumscription in that it includes the genus Didymeles (two species of evergreen trees from Madagascar). Didymeles is a Genus of Flowering plants It is variously treated in the family Buxaceae, or as the only genus of the family Didymelaceae However, APG II does allow the option of segregating this genus as family Didymelaceae, as an optional segregate. Didymelaceae is a family of Flowering plants. The family has been recognised by a fair number of taxonomists at least over the past few decades In taxonomy, a segregate, or a segregate taxon is created when a Taxon is split off from another taxon This represents a slight change from the APG system of 1998, which firmly recognised both families as separate. In both APG and APG II the family Buxaceae is unplaced as to order and left among the basal lineages of the eudicots. Eudicots and Eudicotyledons are terms introduced by Doyle & Hotton (1991 to refer to a group of Flowering plants that had been called "tricolpates" or "non-Magnoliid The AP website suggests instating the order Buxales for this family and the family Didymelaceae. Buxales is a Botanical name at the rank of order Under the APG II system, Buxaceae is a family unplaced as to order in the Eudicots.
