The plant family Hypericaceae was named and described as such by Antoine Laurent de Jussieu in Genera Plantarum in 1789.

As of 12-19-23 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. Of the six genera in the family, only Hypericum species are found in North America.

I am only familiar with two species in this family. I found a Hypericum punctatum (Spotted St. John’s Wort). on my farm in 2019 and a colony of Hypericum perforatum (Common St John’s Wort) on a back road in 2022. You can click on the names to go to their pages. The Missouri Plants website lists 10 species of Hypericum in Missouri, so perhaps I will run across another species at some point.
