Acalypha Rubrinervis
''Acalypha rubrinervis'' (string tree or stringwood) is an extinct plant in the spurge family (Euphorbiaceae), from the island of Saint Helena in the South Atlantic Ocean. It was called string tree on account of the thin pendulous inflorescences which resembled red strings. Disturbance following human settlement on the island destroyed its habitat and it was last seen in the 19th century. It is thus one of a number of island plants to have been driven to extinction by human activity (see List of extinct plants). The genus to which it belongs, ''Acalypha'', is a large one and includes island endemics as well as weeds and ornamentals. ''A. rubrinervis'' was a shrub or thicket growing on the central ridge of St Helena above 600 m elevation. ''Acalypha rubrinervis'' is a shrub or small tree, 1–2 m. Branches with warty leaf-scars. Leaves ovate to broadly triangular-ovate, entire to somewhat wavy-toothed, with 3 veins from the base of the leaf blade 5-7 x 3–5 cm, leaf stalk 2 ...

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. 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. His father may have worked in the Underwood estate or he may have been the illegitimate son of a well-connected family. His early education was at Underwood parish school perhaps also with some time at Symington parish school, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Extinctions Since 1500
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ability ...

Extinct Plants
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

William John Burchell
__NOTOC__ William John Burchell (23 July 1781 – 23 March 1863) was an English explorer, naturalist, traveller, artist, and author. His thousands of plant specimens, as well as field journals from his South African expedition, are held by Kew Gardens, and his insect collection by the Oxford University Museum. Early life and education William John Burchell was born in Fulham, London, the son of Matthew Burchell, botanist and owner of Fulham Nursery, and his wife. His father owned nine and a half acres of land adjacent to the gardens of Fulham Palace. Burchell served a botanical apprenticeship at Kew and was elected F.L.S. (Fellow of the Linnaen Society) in 1803. At about this time, he became enamoured of Lucia Green of Fulham, but faced strong disapproval from his parents when he broached the idea of an engagement. Career On 7 August 1805 Burchell at the age of 24 sailed for St. Helena aboard the East Indiaman intending to set up there as a merchant with a partner from Lond ...

Diana's Peak
Diana's Peak is the highest point, at , on the island of Saint Helena, a British overseas territory in the South Atlantic Ocean. It is of volcanic origin. The mountain and its surroundings with a total area of 81 ha were proclaimed a national park in March 1996, the first on the island. It is a preserve of several endangered endemic species, including tree fern, he cabbage and black cabbage trees, and whitewood. The park contains walking paths connecting the peaks - Mt. Actaeon (814m), Diana's Peak and Cuckold's Point (815m). The two shorter peaks are topped by large Norfolk pines. On the northern slopes there is a nursery for endemic species. The peak is located at the tripoint where the districts of Sandy Bay (southwest), Levelwood (east) and Longwood (north) meet. The closest settlements are Bamboo Hedge (the main settlement of Sandy Bay District), Hutt's Gate (in Longwood District) and Levelwood Village.

Euphorbiaceae
Euphorbiaceae, the spurge family, is a large family of flowering plants. In English, they are also commonly called euphorbias, which is also the name of a genus in the family. Most spurges, such as ''Euphorbia paralias'', are herbs, but some, especially in the tropics, are shrubs or trees, such as ''Hevea brasiliensis''. Some, such as ''Euphorbia canariensis'', are succulent and resemble cacti because of convergent evolution. This family has a cosmopolitan global distribution. The greatest diversity of species is in the tropics, however, the Euphorbiaceae also have many species in nontropical areas of all continents except Antarctica. Description The leaves are alternate, seldom opposite, with stipules. They are mainly simple, but where compound, are always palmate, never pinnate. Stipules may be reduced to hairs, glands, or spines, or in succulent species are sometimes absent. The plants can be monoecious or dioecious. The radially symmetrical flowers are unisexual, w ...
