IUCN
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and Data analysis, analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through buildin ...

William Roxburgh
William Roxburgh FRSE FRCPE Linnean Society of London, FLS (3/29 June 1751 – 18 February 1815) was a Scottish people, Scottish surgeon and botanist who worked extensively in India, describing species and working on economic botany. He is known as the founding father of Indian botany. He published numerous works on Indian botany, illustrated by careful drawings made by Indian artists and accompanied by taxonomic descriptions of many plant species. Apart from the numerous species that he named, many species were named in his honour by his collaborators. He was the first to document the existence of the Ganges river dolphin. Early life He was born on 3 June 1751 on the Underwood estate near Craigie, South Ayrshire, Craigie in Ayrshire and christened on 29 June 1751 at the nearby church at Symington, South Ayrshire, Symington.

Asteraceae
Asteraceae () is a large family (biology), family of flowering plants that consists of over 32,000 known species in over 1,900 genera within the Order (biology), order Asterales. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of Extant taxon, extant species in each family is unknown. The Asteraceae were first described in the year 1740 and given the original name Composita, Compositae. The family is commonly known as the aster, Daisy (flower), daisy, composite, or sunflower family. Most species of Asteraceae are herbaceous plants, and may be Annual plant, annual, Biennial plant, biennial, or Perennial plant, perennial, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions, in a wide variety of habitats. Most occur in Hot desert climate, hot desert and cold or hot Semi-arid climate, semi-desert climates, and they are found on ever ...

Saint Helena
Saint Helena (, ) is one of the three constituent parts of Saint Helena, Ascension and Tristan da Cunha, a remote British overseas territory. Saint Helena is a volcanic and tropical island, located in the South Atlantic Ocean, some 1,874 km (1,165 miles) west of the mainland of the continent of Africa, with the Southern African nations of Angola and Namibia on its southeastern coast being the closest nations geographically. The island is around west of the coast of southwestern South Africa, and east of the major seaport city of Rio de Janeiro, Brazil in South America. Saint Helena measures about and had a population of 4,439 in the 2021 census. It was named after Helena, mother of Constantine I, Saint Helena (AD c.246/248–330), influential mother of the famous Roman Emperor Constantine the Great, Saint Constantine I the Great. (A.D 272–337, reigned 306–337), of the ancient Roman Empire. It is one of the most remote major islands in the world and was uninhabited unt ...

Extinct
Extinction is the termination of an organism by the death of its Endling, last member. A taxon may become Functional extinction, functionally extinct before the death of its last member if it loses the capacity to Reproduction, reproduce and recover. As a species' potential Range (biology), range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxon, Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the Fossil, fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include Dinosaur, non-avian dinosaurs, Machairodontinae, saber-toothed cats, and mammoths. Through evolution, species arise through the process of specia ...

Flora Of St Helena
The flora of Saint Helena, an isolated island in the South Atlantic Ocean, is exceptional in its high level of endemism and the severe threats facing the survival of the flora. In phytogeography, it is in the phytochorion St. Helena and Ascension Region of the African Subkingdom, in the Paleotropical Kingdom. Endemic and introduced flora The endemic plants of Saint Helena include many notable Cabbage Tree or, "insular arborescent Asteraceae", members of the daisy family which have evolved a shrubby or tree-like habit on islands. Other notable endemics include the closely related St Helena redwood ('' Trochetiopsis erythroxylon'') and St Helena dwarf ebony ('' Trochetiopsis ebenus''). These are unrelated to the redwood trees of California or to the ebony trees of commerce, being instead in the Mallow family (Malvaceae). Vegetation Today there are three major vegetation zones: the tree-fern thicket of the highest parts of the central ridge; the pastures of middle elevations and t ...

Pladaroxylon Leucadendron
''Pladaroxylon'' is a genus of trees in the tribe Senecioneae within the family Asteraceae. The only known species is ''Pladaroxylon leucadendron'', native to the island of St. Helena in the South Atlantic. Commonly known as the he cabbage-tree. Description ''Pladaroxylon leucadendron'' is a small tree, growing to a maximum of 5 meters in height, with relatively large and cabbage like leaves. On young trees the leaves are very large, often reaching 30 centimeters in length, but on older trees they are usually smaller. They are oval in outline, with a downy underside, and very prominent veins. The trees branch at regular intervals into two equal sized limbs and all the leaves are at the furthest ends of the branches. The first branching is at 1.2–2 meters above the ground. The tree has a broad, rounded canopy when full grown. As typical of the family it has flower heads () with many flowers crowded together in one structure that resembles a single flower, each ...

Senecioneae
Senecioneae is the largest tribe of the Asteraceae, or the sunflower family, comprising over 150 genera and over 3,500 species. Almost one-third of the species in this tribe are placed in the genus ''Senecio''. Its members exhibit probably the widest possible range of form to be found in the entire plant kingdom, and include annuals, minute creeping alpines, herbaceous and evergreen perennials, shrubs, climbers, succulents, trees, and semi-aquatic plants. Plants in this tribe are responsible for more livestock poisonings than all other plants combined. Its members usually contain liver and kidney toxic and carcinogenic unsaturated pyrrolizidine alkaloids in ''Senecio'' and furanoeremophilanes in '' Tetradymia''. A number of species are well known in horticulture. Classification Since the time of Bentham, the "premier systematic botanist of the nineteenth century", considerable efforts have been made to classify and understand the striking morphological diversity in th ...
