George Bentham
George Bentham (22 September 1800 – 10 September 1884) was an English botanist, described by the weed botanist Duane Isely as "the premier systematic botanist of the nineteenth century". Born into a distinguished family, he initially studied law, but had a fascination with botany from an early age, which he soon pursued, becoming president of the Linnaean Society in 1861, and a fellow of the Royal Society in 1862. He was the author of a number of important botanical works, particularly flora. He is best known for his taxonomic classification of plants in collaboration with Joseph Dalton Hooker, his ''Genera Plantarum'' (1862–1883). He died in London in 1884. Life Bentham was born in Stoke, Plymouth, on 22 September 1800.Jean-Jacques Amigo, « Bentham (George) », in Nouveau Dictionnaire de biographies roussillonnaises, vol. 3 Sciences de la Vie et de la Terre, Perpignan, Publications de l'olivier, 2017, 915 p.

Hook
A hook is a tool consisting of a length of material, typically metal, that contains a portion that is curved or indented, such that it can be used to grab onto, connect, or otherwise attach itself onto another object. In a number of uses, one end of the hook is pointed, so that this end can pierce another material, which is then held by the curved or indented portion. Some kinds of hooks, particularly fish hooks, also have a barb, a backwards-pointed projection near the pointed end of the hook to ensure that once the hook is embedded in its target, it can not easily be removed. Variations * Bagging hook, a large sickle or reaping hook used for harvesting grain * Bondage hook, used in sexual bondage play * Cabin hook, a hooked bar that engages into an eye screw, used on doors * Cap hook, hat ornament of the 15th and 16th centuries * Cargo hook (helicopter), different types of hook systems for helicopters * Crochet hook, used for crocheting thread or yarn * Drapery hook, for ha ...

Plant
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 ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Picrodendraceae
Picrodendraceae is a family of flowering plants, consisting of 80 species in 24 genera.Stephens, P.F. (2001 onwards). Angiosperm Phylogeny Website. Version 9, June 2008. http://www.mobot.org/MOBOT/Research/APweb/ These are subtropical to tropical and found in New Guinea, Australia, New Caledonia, Madagascar, continental Africa, and tropical America. Its closest relatives are Phyllanthaceae. This family used to be known as the subfamily Oldfieldioideae of the Euphorbiaceae. Taxonomy The family contains about 80 species organised into three tribes, ten subtribes and 24 genera. Genera * '' Androstachys'' * '' Aristogeitonia'' * ''Austrobuxus'' * '' Celaenodendron'' * '' Choriceras'' * '' Dissiliaria'' * '' Hyaenanche'' * ''Kairothamnus'' * ''Longetia'' * ''Micrantheum'' * ''Mischodon'' * ''Neoroepera'' * ''Oldfieldia'' * ''Paradrypetes'' * '' Parodiodendron'' * '' Petalostigma'' * '' Picrodendron'' * '' Piranhea'' * '' Podocalyx'' * ''Pseudanthus'' * ''Scagea ''Scagea'' i ...

Subtribe
Subtribe is a taxonomic category ranking which is below the rank of tribe and above genus. The standard suffix for a subtribe is -ina (in animals) or -inae (in plants 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 early use of this word is from 19th century. An example of subtribe is Hyptidinae that contains approximately 400 accepted species distributed in 19 genera.

Endemic
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oldfieldia Africana
Oldfieldia africana, also known as the African oak, is a large tree which can grow to 36 metres or more in height. It is to be found across West Africa in such countries as Ivory Coast, Liberia, Sierra Leone, Gabon, Cameroon, Central African Republic, Congo Republic. Numbers have decreased as its timber is very heavy and hard, comparable to teak. John MacCormac an Irish businessman who settled on the banks of the Rokel River, Sierra Leone for example, established the local timber trade in 1816, and for a while enjoyed a substantial income from it. Medicinal uses The bark maybe used as an antiseptic and haemostatic. It can also be added to various herbs in order to increase their potency. Another use is a decoction of the barkwhich can be added to baths or draughts as a treatment for blennorrhoea. The powdered bark can be used in a dressing to hasten healing or to treat sores. The bark can be boiled with palm-oil Palm oil is an edible vegetable oil derived from the mesocarp ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
