Hypericum sechmenii, or Seçmen's St John's wort, is a rare species of flowering plant of the St John's wort family (Hypericaceae) that is found in the Eskişehir Province of central Turkey. It was first described in 2009 by Turkish botanists Atila Ocak and Onur Koyuncu, who named the species in honor of Özcan Seçmen, a fellow botanist. They assigned the species to the genus Hypericum, and Norman Robson later placed H. sechmenii into the section Adenosepalum.
Hypericum sechmenii is a perennial herb that usually grows in clusters of stems 3–6 centimeters (1–2 inches) tall and blooms in June and July. The stems of the plant are smooth and lack hairs, while the leaves are leathery and do not have leafstalks. Its flowers are arranged in clusters that form a flat-topped shape known as a corymb, and each flower possesses five bright yellow petals. Several species are similar in appearance to H. sechmenii, with only minor physical differences that set them apart. The most closely related of these are Hypericum huber-morathii, Hypericum minutum, and Hypericum thymopsis.
Found among limestone rocks, Hypericum sechmenii has an estimated distribution of less than 10 square kilometers (4 square miles), with fewer than 250 surviving plants. Despite containing druse crystals and toxic chemicals that are thought to deter herbivory, the species is threatened by overgrazing from livestock, as well as by other factors like climate change and habitat loss.
