Theophrastoideae

Taxonomy.
The APG II system placed this family in the order Ericales, a basal group in the asterids. APG II also included the additional genus "Samolus", with about 15 additional species, vastly increasing the area of distribution. The 2009 APG III system onwards includes the family within an enlarged Primulaceae ("sensu lato").
