Euphorbia Obtusifolia
The scientific name ''Euphorbia obtusifolia'' has been used for at least three species of ''Euphorbia'': *''Euphorbia obtusifolia'' is a synonym of ''Euphorbia terracina'' , native from Macaronesia through Hungary and the Mediterranean to the Arabian Peninsula *''Euphorbia obtusifolia'' is an illegitimate name that has been applied to: **'' Euphorbia lamarckii'' – of which it is a synonym; native to the western Canary Islands (Tenerife, La Gomera, La Palma and El Hierro); also known by the synonym ''Euphorbia broussonetii'' **'' Euphorbia regis-jubae'' – with which it has been confused; native to the eastern Canary Islands (Gran Canaria, Lanzarote and Fuerteventura), west Morocco and north-western Western Sahara References {{reflist, refs= {{Citation , last1=Bramwell , first1=David , date=2003 , title=Observations on a proposal to conserve the name ''Euphorbia obtusifolia'' Poiret. , journal=Botánica Macaronésica , issue=24 , pages=143–147 , url=https://www.researchgate ...

Euphorbia
''Euphorbia'' is a very large and diverse genus of flowering plants, commonly called spurge, in the family Euphorbiaceae. "Euphorbia" is sometimes used in ordinary English to collectively refer to all members of Euphorbiaceae (in deference to the type genus), not just to members of the genus. Euphorbias range from tiny annual plants to large and long-lived trees. The genus has roughly 2,000 members, making it one of the largest genera of flowering plants. It also has one of the largest ranges of chromosome counts, along with ''Rumex'' and ''Senecio''. '' Euphorbia antiquorum'' is the type species for the genus ''Euphorbia''. It was first described by Carl Linnaeus in 1753 in ''Species Plantarum''. Some euphorbias are widely available commercially, such as poinsettias at Christmas. Some are commonly cultivated as ornamentals, or collected and highly valued for the aesthetic appearance of their unique floral structures, such as the crown of thorns plant ('' Euphorbia milii'' ...

Euphorbia Terracina
''Euphorbia terracina'', commonly known as the Geraldton carnation weed and False caper, is a species of perennial herb in the family Euphorbiaceae. It has a self-supporting growth form and simple, broad leaves. Flowers are visited by '' Lipotriches brachysoma'', '' Lipotriches natalensis'', '' Lipotriches crassula'', and ''Nomia bouyssoui''. It produces small, three lobed fruits, with each lobe containing one seed. Distribution ''Euphorbia terracina'' is natively distributed in Mediterranean climate regions of Northern Africa, temperate Asia, and some areas of Europe. It is an invasive weed in other similar climate regions mainly in Australia and the U.S. state of California. It allelopathically inhibitit growth of surrounding plants. Toxicity ''Euphorbia terracina'' is toxic to both humans and livestock. As with many other Euphorbia species, exposure to its milky sap may cause irritation to skin, eyes, and digestive tracts. Uses In some regions of Algeria, the sap of '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macaronesia
Macaronesia (Portuguese: ''Macaronésia,'' Spanish: ''Macaronesia'') is a collection of four volcanic archipelagos in the North Atlantic, off the coasts of Africa and Europe. Each archipelago is made up of a number of Atlantic oceanic islands, which are formed by seamounts on the ocean floor whose peaks have risen above the ocean's surface. Some of the Macaronesian islands belong to Portugal, some belong to Spain, and the rest belong to Cape Verde. Politically, the islands belonging to Portugal and Spain are part of the European Union. Geologically, Macaronesia is part of the African tectonic plate. Some of its islands – the Azores – are situated along the edge of that plate at the point where it abuts the Eurasian and North American plates. In one biogeographical system, the Cape Verde archipelago is in the Afrotropical realm while the other three archipelagos are in the Palearctic realm. According to the European Environment Agency, the three European archipelagos const ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Euphorbia Lamarckii
''Euphorbia lamarckii'' is a species of flowering plant in the family Euphorbiaceae, native to the western Canary Islands (Tenerife, north-western La Gomera, La Palma and El Hierro). It resembles '' Euphorbia regis-jubae'', with which it has been confused. Both have been called ''Euphorbia obtusifolia''. Description ''Euphorbia lamarckii'' resembles '' Euphorbia regis-jubae''; their distributions do not overlap. It is a shrub up to tall, with light brown stems, undivided leaves and small yellowish-green floral bracts. The inflorescence is usually a compound umbel. The elaiosome (caruncle) attached to a seed is sessile or has only a very short stalk. It differs from other Canary Island species of ''Euphorbia'' in the shape of the compound, umbel-like inflorescences, that are yellow-greenish in colour, and by the floral bracts falling off before the fruit ripens.

Euphorbia Regis-jubae
''Euphorbia regis-jubae'' is a species of flowering plant in the family Euphorbiaceae, native to the eastern Canary Islands, western Morocco, north-western Western Sahara. In Spanish, it is known as . It has often been confused with '' Euphorbia lamarckii''. The specific epithet ''regis-jubae'', meaning 'King Juba's euphorbia' honours the king's contributions to natural history and his role in bringing the genus to notice. The palm tree genus '' Jubaea'' is also named after Juba. Description ''Euphorbia regis-jubae'' is a shrub, up to tall. It has light brown stems and terminal rosettes of leaves that are narrow and oblong, with a pointed or somewhat blunt apex. The inflorescences are pedunculate, umbel-like, usually simple with five to eight rays, more rarely compound. The greenish-yellow floral bracts are large, not joined at the base, and persist when the fruit has formed. The fruit capsules are light brown or red. The seeds have a stalked elaiosome (caruncle).

World Checklist Of Selected Plant Families
The World Checklist of Selected Plant Families (usually abbreviated to WCSP) is an "international collaborative programme that provides the latest peer reviewed and published opinions on the accepted scientific names and synonyms of selected plant families." Maintained by the Royal Botanic Gardens, Kew, it is available online, allowing searches for the names of families, genera and species, as well as the ability to create checklists. The project traces its history to work done in the 1990s by Kew researcher Rafaël Govaerts on a checklist of the genus '' Quercus''. Influenced by the Global Strategy for Plant Conservation, the project expanded. , 173 families of seed plants were included. Coverage of monocotyledon families is complete; other families are being added. There is a complementary project called the International Plant Names Index (IPNI), in which Kew is also involved. The IPNI aims to provide details of publication and does not aim to determine which are accep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Botanic Gardens, Kew
Royal Botanic Gardens, Kew is a non-departmental public body in the United Kingdom sponsored by the Department for Environment, Food and Rural Affairs. An internationally important botanical research and education institution, it employs 1,100 staff. Its board of trustees is chaired by Dame Amelia Fawcett. The organisation manages botanic gardens at Kew in Richmond upon Thames in south-west London, and at Wakehurst, a National Trust property in Sussex which is home to the internationally important Millennium Seed Bank, whose scientists work with partner organisations in more than 95 countries. Kew, jointly with the Forestry Commission, founded Bedgebury National Pinetum in Kent in 1923, specialising in growing conifers. In 1994, the Castle Howard Arboretum Trust, which runs the Yorkshire Arboretum, was formed as a partnership between Kew and the Castle Howard Estate. In 2019, the organisation had 2,316,699 public visitors at Kew, and 312,813 at Wakehurst. Its site ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
