The plant family Hypericaceae was named and described as such by Antoine Laurent de Jussieu in Genera Plantarum in 1789.
As of 11-27-21 when this page was last updated, Plants of the World Online lists six genera in this family commonly known as the St. John’s Wort family.
The only species I am familiar with is Hypericum punctatum (Spotted St. John’s Wort). I may have located Hypericum perforatum (Common St. John’s Wort) but I have to go back to the location to verify.
