The APG II system of 2003 does not recognise the family as such, the plants involved being included in the family Buxaceae. However, APG II does allow the option of segregating this family, as an optional segregate; it is then unplaced as to order and left among the basal lineages of the eudicots. The APG III system of 2009 also does not recognise Didymelaceae but includes the genus Didymeles in the Buxaceae under the order Buxales in the eudicots.
This represents a slight change from the APG system, of 1998, which firmly did recognised the family, with the same placement.
