Adam Afzelius
Adam Afzelius (8 October 175020 January 1837) was a Swedish botanist and an apostle of Carl Linnaeus. Afzelius was born at Larv in Västergötland in 1750. He was appointed teacher of oriental languages at Uppsala University in 1777, and in 1785 demonstrator of botany. In 1793 he was elected a member of the Royal Swedish Academy of Sciences. In 1800, Adam Afzelius became member of the German Academy of Sciences Leopoldina. Between 1792 and 1796, as part of the Sierra Leone Company, he made two journeys to West Africa, where he reported on the geography, climate and natural resources of the region. While here, he also collected botanical specimens that were later acquired by Uppsala University.Afzelius, Adam (1750-1837) at JSTOR Global Plants In 1797-98 he acted as secretary of the Swedish |
Carl Frederik Von Breda
Carl Frederik von Breda (16 August 1759 – 1 December 1818) was a Swedish painter who studied in and spent much of his career in Britain before becoming painter to the Swedish court. He was born in Stockholm in 1759, and moved to Britain where he was a student of Joshua Reynolds. Breda specialized in painting portraits and was called "the van Dyck of Sweden". He returned to Sweden 1796 where he became professor at the Academy of Arts, a popular portraitist, and a court painter. Breda married at age 22 and his son, Johan Fredrik, was also a painter, who studied under his father. Breda died in Stockholm in 1818. Breda painted James Watt. Early life Breda's great-grandfather Pieter emigrated to Stockholm around the year 1670 from the Netherlands. The "von Breda" family name seems to indicate a connection with the city of Breda. ''Von'' is not a Dutch preposition, but in the Nordic countries, this originally German preposition has occasionally been used as a part of names of en ...

Embassy
A diplomatic mission or foreign mission is a group of people from a state or organization present in another state to represent the sending state or organization officially in the receiving or host state. In practice, the phrase usually denotes an embassy, which is the main office of a country's diplomatic representatives to another country; it is usually, but not necessarily, based in the receiving state's capital city. Consulates, on the other hand, are smaller diplomatic missions that are normally located in major cities of the receiving state (but can be located in the capital, typically when the sending country has no embassy in the receiving state). As well as being a diplomatic mission to the country in which it is situated, an embassy may also be a nonresident permanent mission to one or more other countries. The term embassy is sometimes used interchangeably with chancery, the physical office or site of a diplomatic mission. Consequently, the terms "embassy resi ...

Elias Magnus Fries
Elias Magnus Fries (15 August 1794 – 8 February 1878) was a Swedish mycologist and botanist. Career Fries was born at Femsjö ( Hylte Municipality), Småland, the son of the pastor there. He attended school in Växjö. He acquired an extensive knowledge of flowering plants from his father. In 1811 Fries entered Lund University where he obtained a doctorate in 1814. In the same year he was appointed an associate professorship in botany. He was elected a member of the Royal Swedish Academy of Sciences, and in 1824, became a full professor. In 1834 he became Borgström professor (Swed. ''Borgströmianska professuren'', a chair endowed by Erik Eriksson Borgström, 1708–1770) in applied economics at Uppsala University. The position was changed to "professor of botany and applied economics" in 1851. He was elected a Foreign Honorary Member of the American Academy of Arts and Sciences in 1849. That year he was also appointed director of the Uppsala University Botanic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Heinrich Wilhelm Schott
Heinrich Wilhelm Schott (7 January 1794 in Brünn (Brno), Moravia – 5 March 1865 at Schönbrunn Palace, Vienna) was an Austrian botanist well known for his extensive work on aroids (Araceae). He studied botany, agriculture and chemistry at the University of Vienna, where he was a pupil of Joseph Franz von Jacquin (1766–1839). He was a participant in the Austrian Brazil Expedition from 1817 to 1821. In 1828 he was appointed ''Hofgärtner'' (royal gardener) in Vienna, later serving as director of the Imperial Gardens at Schönbrunn Palace (1845). In 1852 he was in charge of transforming part of palace gardens in the fashion of an English garden. He also enriched the Viennese court gardens with his collections from Brazil. He was also interested in Alpine flora, and was responsible for development of the alpinum at Schloss Belvedere in Vienna. In 2008, botanists P.C.Boyce & S.Y.Wong published '' Schottarum'', a genus of flowering plants from Borneo belonging to the family ...

Anubias Afzelii
''Anubias afzelii'' is a species belonging to the Aroid genus ''Anubias''. It was first described scientifically by Heinrich Wilhelm Schott in 1857, based on material collected in Sierra Leone by Adam Afzelius, after whom the species was named. The genus ''Anubias'' was described simultaneously, with only ''A. afzellii'' belonging to it, which therefore is the type species of the genus. No other species currently placed in the genus ''Anubias'' was described earlier (in a different genus) and ''A. afzelii'' was therefore the first species of this genus known to science. Distribution West Africa: Senegal, Guinea, Sierra Leone, and Mali. Description ''Anubias afzelii'' has elongated, leathery leaf blades that can be up to 35 cm long and 13 cm wide. The leaf stems are generally shorter than the blade. The leaves are set on a creeping and rooting rhizome that is 1–4 cm thick. The spathe is 3–7 cm long (exceptionally up to 9 cm long) and has a 13 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caesalpinioideae
Caesalpinioideae is a botanical name at the rank of subfamily, placed in the large family Fabaceae or Leguminosae. Its name is formed from the generic name ''Caesalpinia''. It is known also as the peacock flower subfamily. The Caesalpinioideae are mainly trees distributed in the moist tropics, but include such temperate species as the honeylocust (''Gleditsia triacanthos'') and Kentucky coffeetree (''Gymnocladus dioicus''). It has the following clade-based definition: The most inclusive crown clade containing ''Arcoa gonavensis'' Urb. and ''Mimosa pudica'' L., but not '' Bobgunnia fistuloides'' (Harms) J. H. Kirkbr. & Wiersema, ''Duparquetia orchidacea'' Baill., or '' Poeppigia procera'' C.Presl In some classifications, for example the Cronquist system, the group is recognized at the rank of family, Caesalpiniaceae.

Afzelia
''Afzelia'' is a genus of plants in family Fabaceae. The thirteen species all are trees, native to tropical Africa or Asia. The genus name of ''Afzelia'' is in honour of Adam Afzelius (1750–1837), a Swedish botanist and an apostle of Carl Linnaeus. Uses ''Afzelia'' species are used primarily for wood, though some species also have medicinal uses. The timber is most commonly traded under the collective name "doussie", as well as under name "afzelia". One of the common names is also "pod mahogany", adding to the confusion surrounding the name mahogany. The seeds are red and black and are used as beads. The wood is often used as the surface material for outdoor velodromes. The highly figured wood of the Asian species, ''Afzelia xylocarpa'', is sold as Afzelia xylay. The seeds and bark of this species are used as medicine. The dense and wavy wood of an ''Afzelia africana ''Afzelia africana'', the African mahogany, afzelia, lenke, lengue, apa, or doussi, is a tree species ...

Chemistry
Chemistry is the scientific study of the properties and behavior of matter. It is a natural science that covers the elements that make up matter to the compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances. Chemistry also addresses the nature of chemical bonds in chemical compounds. In the scope of its subject, chemistry occupies an intermediate position between physics and biology. It is sometimes called the central science because it provides a foundation for understanding both basic and applied scientific disciplines at a fundamental level. For example, chemistry explains aspects of plant growth ( botany), the formation of igneous rocks ( geology), how atmospheric ozone is formed and how environmental pollutants are degraded ( ecology), the properties of the soil on the moon ( cosmochemistry), how medications work ( pharmacology), and how to collec ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his Nobility#Ennoblement, ennoblement in 1761 as Carl von Linné#Blunt, Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In ...
