Hypericum sect. Adenotrias is a section of flowering plants in the family Hypericaceae. It is made up of Hypericum aciferum, H. aegypticum, and H. russeggeri. Species in the section are shrubs up to 2 metres (6.6 ft) tall with smooth leaves and bark, and are the only species in Hypericum with heterostylous flowers. They are found around the Mediterranean coast, with H. aciferum restricted to the island of Crete and H. russeggeri present only in parts of Turkey and Syria. Plants of the section have a habitat among limestone and other calcareous rocks. While H. aegypticum has a wide and generally secure distribution, H. aciferum was evaluated as endangered several times since the 1980s although it is now considered only vulnerable because it is protected in part by a plant micro-reserve.
