The family Hypericaceae includes 7 genera and about 700 species. One genus, Hypericum is known from Somaliland (Regions N1-2 of the Flora of Somalia), but not from Somalia. It is also the only genus of Hypericaceae known from Pakistan.
Hypericum used to be included in the Guttiferae, but that family has been split into two families, Clusiaceae and Hypericaceae. Guttiferae refers to the Clusiaceae.
