Hypericum miocenicum
Hypericum miocenicum is an extinct species of the genus Hypericum. Seeds of the species have been recorded from the Late Oligocene in Germany, the Late Miocene in Poland, and the Pliocene in Germany. It differs from H. septestum, a more frequently found Hypericum paleospecies, by its thinner foveole walls and the shape of its surface cells, which are more rectangular.
