Hypericum Russeggeri
''Hypericum russeggeri'' is a species of flowering plant in the St John's wort family Hypericaceae. The plant is a small shrub with many branches that spread across the ground, and it has many small flowers with pale yellow petals. It is found only among calcareous rocks along the coast and in the foothills of the Nur Mountains of eastern Turkey and northern Syria. While ''H. russeggeri'' has an array of phytochemicals present in its flowering structures and leaves, these are found in lower concentrations than other species of ''Hypericum''. The species was first described in 1842 as ''Triadenia russeggeri'', and it has been placed into various defunct genera including ''Elodea'' and ''Adenotrias''. It is now known as ''Hypericum russeggeri'' and is the type species of ''Hypericum'' section ''Adenotrias'', a small section that also includes '' H. aegypticum'' and '' H. aciferum''.

Hypericum Aciferum
''Hypericum aciferum'' is a species of flowering plant in the St John's wort family Hypericaceae. It is a small shrub endemic to the Greek island of Crete. ''H. aciferum'' grows in a mat on the ground and has twisting branches, needle-like leaves, and long golden petals. Its flowers are also heterostylous, which means that the species can exhibit one of two flower types on different plants. This trait is unique within the genus ''Hypericum'' to ''H. aciferum'', '' H. russeggeri'', and '' H. aegypticum'', the three species in section ''Adenotrias''. The species was described by Werner Greuter in 1965 as ''Elodes acifera'', and was later placed into section ''Adenotrias'' of the genus ''Hypericum'' by Norman Robson in 1984. ''Hypericum aciferum'' has an extremely limited distribution in the southwest corner of Crete, and is found in rock crevices. It was assessed as endangered several times in the 1980s and 1990s, due to a small population and threats from grazing and fire. It was ...

The plant is commonly known as shrubby St. John's wort or Egyptian St. John's wort in English. Like other members of section '' Adenotrias'', it is found among limestone rocks in coastal areas.

Hypericum
''Hypericum'' is a genus of flowering plants in the family Hypericaceae (formerly considered a subfamily of Clusiaceae). The genus has a nearly worldwide distribution, missing only from tropical lowlands, deserts and polar regions. Many ''Hypericum'' species are regarded as invasive species and noxious weeds. All members of the genus may be referred to as St. John's wort, and some are known as goatweed. The white or pink flowered marsh St. John's worts of North America and eastern Asia are generally accepted as belonging to the separate genus ''Triadenum'' Raf. ''Hypericum'' is unusual for a genus of its size because a worldwide taxonomic monograph was produced for it by Norman Robson (working at the Natural History Museum, London). Robson recognizes 36 sections within ''Hypericum''. Description ''Hypericum'' species are quite variable in habit, occurring as trees, shrubs, annuals, and perennials. Trees in the sense of single stemmed woody plants are rare, as most woody s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
