The Buxaceae are a small family of six genera and about 123 known species[2] of flowering plants.

A seventh genus, sometimes accepted in the past (Notobuxus), has been shown by genetic studies to be included within Buxus (Balthazar et al., 2000).

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).

This represents a slight change from the APG system of 1998, which firmly recognised both families as separate.

In the APG IV system of 2016, Haptanthus and Didymeles are included in Buxaceae, which is the only family in Buxales.
