Hypericum elegans is a species of flowering plant in the St. John's wort family Ericaceae. It is native to Europe.
The larvae of the moth Euspilapteryx auroguttella feed on H. elegans.
Hypericum perforatum, commonly known as St John's wort, is a flowering plant in the family Hypericaceae. It is a perennial plant that grows up to one meter tall, with many yellow flowers that have clearly visible black glands around their edges, long stamens, and three pistils. Probably a hybrid between the closely related H. attenuatum and H. maculatum that originated in Siberia, the species is now found worldwide. It is native to temperate regions across Eurasia and North Africa, and has been introduced to East Asia, Australia, New Zealand, and parts of North and South America. In many areas where it is not native, H. perforatum is considered a noxious weed. It densely covers open areas to the exclusion of native plants, and is poor grazing material. As such, methods for biocontrol have been introduced in an attempt to slow or reverse the spread of the species.
Hypericum is a genus of flowering plants in the family Hypericaceae. 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 TriadenumRaf.
Hypericum concinnum is a species of flowering plant known as gold-wire or goldwire. It is in the St. John's wort family, Hypericaceae. It is the only species in the section Hypericum sect. Concinna.
Hypericum androsaemum, the shrubby St. John's wort, is a flowering plant in the family Hypericaceae. Commonly called tutsan or sweet-amber, the species is cultivated as an ornamental plant because of its striking red-tinted foliage, bright yellow petals, and its large clusters of fruit. Cultivars like 'Albury Purple' and 'Golden Tutsan' which have leaves with more pronounced purple and golden coloring, respectively.
H. elegans may refer to:
Euspilapteryx auroguttella is a moth of the family Gracillariidae. It is known from all of Europe.
Hypericum ericoides is a dwarf shrub in the flowering plant family Hypericaceae, section Coridium. It is found in eastern and southeastern Spain, Morocco, and Tunisia. Its preferred habitat is fissures in calcareous rocks in warm, sunny places, from 200 to 2,000 meters above sea level (MASL).
Hypericum aegypticum is a species of flowering plant of the St. John's wort family (Hypericaceae) which is native to the Eastern Mediterranean. It was described by Carl Linnaeus in the second volume of his Species Plantarum in 1753, who named it after Egypt despite it not being distributed there. 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. While it has been evaluated as threatened on the island of Malta, the species has no legal protections.
Hypericum cerastioides is a species of perennial flowering plant in the St. John's wort family, Hypericaceae. It is the only species in the section Hypericum sect. Campylopus.
Hypericum sect. Adenosepalum is one of 36 sections in the genus Hypericum. Its type species is Hypericum montanum.
Hypericum lacei is a shrub in Hypericumsect. Ascyreia, in the St. John's Wort genus.
Hypericum assamicum is a species of flowering plant in the St. John's wort family, Hypericaceae. It is endemic to India. Hypericum assamicum is one of two species of Hypericum in the section Hypericum sect. Sampsonia.
Hypericum patulum, known as goldencup St. John's wort or yellow mosqueta, is a species of flowering plant in Hypericumsect. Ascyreia.
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 huber-morathii is a flowering plant in the family Hypericaceae, section Adenosepalum, and the type species of the Hypericum huber-morathii group.
Hypericum antiquum is an extinct species of the genus Hypericum that was present during the Eocene epoch. The species' fossils are the oldest collected of Hypericum, and it is believed that the species is the common ancestor of the tribe Hypericeae. Fossil seeds have been found in Russia, and the predicted paleoregion of the species stretched across Eurasia. It is theorized that one factor leading to the species' extinction is a global cooling at the end of the Eocene that removed much of its habitat.
Hypericum pallens, commonly known as the Pale St. John's wort or Mount Lebanon St. John's wort, is a species of flowering plant in the family Hypericaceae which is found in Turkey, Lebanon, and Syria.
Hypericum monanthemum is a species of flowering plant of the St. John's wort family (Hypericaceae) which is native to the Himalayan mountains.
Hypericum foveolatum is an extinct species of the genus Hypericum. The paleospecies is known from more recent fossils than many other Hypericum specimens, with fossilized seeds from the Pliocene epoch being found in Russia and Belarus. These seeds have been compared to numerous extant species, including H. elegans, H. tetrapterum, H. attenuatum, H. kamtschaticum, H. yezoënse, H. nudiflorum, and H. microsepalum. However, none of these similar species have the exact same kind of testa surface cells as H. foveolatum.
