The segregation of Hypericaceae from Guttiferae is confirmed by recent molecular research (APG III). The latter has no representatives in Belgium.

The family is represented by a single genus in Belgium, Hypericum. A North American species from a second genus, Triadenum fraseri (Spach) Gleason, is known from a fen in western Germany - relatively close to the Belgian frontiers - since 2011 and looks firmly established (Klasing & al. 2016). A further expansion cannot be excluded.
