Myrtaceae
Myrtaceae (), the myrtle family, is a family of dicotyledonous plants placed within the order Myrtales. Myrtle, pōhutukawa, bay rum tree, clove, guava, acca (feijoa), allspice, and eucalyptus are some notable members of this group. All species are woody, contain essential oils, and have flower parts in multiples of four or five. The leaves are evergreen, alternate to mostly opposite, simple, and usually entire (i.e., without a toothed margin). The flowers have a base number of five petals, though in several genera, the petals are minute or absent. The stamens are usually very conspicuous, brightly coloured, and numerous. Evolutionary history Scientists hypothesize that the family Myrtaceae arose between 60 and 56 million years ago (Mya) during the Paleocene era. Pollen fossils have been sourced to the ancient supercontinent Gondwana. The breakup of Gondwana during the Cretaceous period (145 to 66 Mya) geographically isolated disjunct taxa and allowed for rapid ...

Jean Armand Isidore Pancher
Jean Armand Isidore Pancher (1 January 1814, in Versailles (city), Versailles – 8 March 1877) was a French gardener and botanist. Beginning in 1835, he worked as gardener with at Muséum National d'Histoire Naturelle in Paris. From 1849 to 1856, he served as a "jardinier colonial" in Tahiti, then as a government botanist in New Caledonia, based in Nouméa (1857–1869). After spending several years in France, he returned to the South Pacific in 1874 as a plant collector in the employ of Belgian horticulturist Jean Jules Linden. In 1877, he died in New Caledonia in an area between La Foa and Moindou.JSTOR Global Plants biographyBiodiversity Heritage Library [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adolphe-Théodore Brongniart
Adolphe-Théodore Brongniart () FRS FRSE FGS (14 January 1801 – 18 February 1876) was a French botanist. He was the son of the geologist Alexandre Brongniart and grandson of the architect, Alexandre-Théodore Brongniart. Brongniart's pioneering work on the relationships between extinct and existing plants has earned him the title of father of paleobotany. His major work on plant fossils was his ' (1828–37). He wrote his dissertation on the Buckthorn family (Rhamnaceae), an extant family of flowering plants, and worked at the Muséum national d'Histoire naturelle in Paris until his death. In 1851, he was elected a foreign member of the Royal Swedish Academy of Sciences. This botanist is denoted by the author abbreviation when citing a botanical name. Brongniart's works Brongniart was an indefatigable investigator and a prolific writer of books and memoirs. As early as 1822, he published a paper on the classification and distribution of fossil plants. This was followed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean Antoine Arthur Gris
Jean Antoine Arthur Gris (11 December 1829 – 19 August 1872) was a French botanist who was a native of Châtillon-sur-Seine, in the department of Côte-d'Or. Beginning in 1855 he worked in the laboratory of Adolphe-Théodore Brongniart (1801-1876) at the Muséum national d'histoire naturelle in Paris. In 1859 he received his PhD with a dissertation involving microscopic studies of chlorophyll. He was the author of 80 scientific articles, the majority of them being published in the ''Bulletin de la Société botanique de France'' and the ''Annales des sciences naturelles''. In 1865, Brongniart named the genus ''Grisia'' (synonym: '' Bikkia'', family: Rubiaceae Rubiaceae () is a family (biology), family of flowering plants, commonly known as the coffee, madder, or bedstraw family. It consists of terrestrial trees, shrubs, lianas, or herbs that are recognizable by simple, opposite leaves with Petiole ( ...) in his honor.

Max Burret
Karl Ewald Maximilian Burret, commonly known as Max Burret (6 June 1883 – 19 September 1964) was a German botanist. Burret was born in Saffig near Andernach in the Kingdom of Prussia, Prussian Rhine Province. He originally studied law at Lausanne and Munich at the instigation of his father. Burret had a greater interest in natural science than in law, and he eventually abandoned his law studies to conduct botany, botanical research in Berlin, where he earned a Ph.D. in 1909 for his Taxonomy (biology), taxonomic thesis, and quickly became one of Germany's most prominent botanists. Burret participated in many botanical science organizations in Germany, taking up leadership positions, such as assistant at the Berlin Botanical Museum and Garden from 1909 to 1911, as well as botanical assistant and lecturer at the Botanical Institute of the Agricultural College in Berlin in 1911 through 1921. In 1922 he was appointed custodian of the Botanical Museum and Garden in Berlin, and l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or bec ...

New Caledonia
New Caledonia ( ; ) is a group of islands in the southwest Pacific Ocean, southwest of Vanuatu and east of Australia. Located from Metropolitan France, it forms a Overseas France#Sui generis collectivity, ''sui generis'' collectivity of the French Republic, a legal status unique in overseas France, and is enshrined in a dedicated chapter of the French Constitution. The archipelago, part of the Melanesia subregion, includes the main island of Grande Terre (New Caledonia), Grande Terre, the Loyalty Islands, the Chesterfield Islands, the Belep archipelago, the Isle of Pines (New Caledonia), Isle of Pines, and a few remote islets. The Chesterfield Islands are in the Coral Sea. French people, especially locals, call Grande Terre , a nickname also used more generally for the entire New Caledonia. Kanak people#Agitation for independence, Pro-independence Kanak parties use the name (''pron.'' ) to refer to New Caledonia, a term coined in the 1980s from the ethnic name of the indi ...

Monotypic Myrtaceae Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical system. ...

Taxa Named By Adolphe-Théodore Brongniart
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
