Hans Melchior
Hans Melchior (5 August 1894 – 12 March 1984) was a German botanist. Melchior was born in Berlin. He studied botany at Berlin University, became assistant to G. Haberlandt at the Institute for plant physiology and took his doctor's degree with him in 1920. Later he was assistant at the Botanical Museum and Herbarium, Berlin-Dahlem, on 1 October 1920, the beginning of an uninterrupted career at that institute in which he went through all the ranks, ending as interim director (1958–1959), and having been professor of botany from 1940 teaching at Technical University of Berlin. Among his many contributions to taxonomy are his treatments of the Medusagynaceae, Theaceae, Violaceae, and Canellaceae for the second edition of the '' Die Natürlichen Pflanzenfamilien'' of Engler & K. Prantl, the publication as editor with E. Werdermann, of ed. 12 (1954-1964) of Engler's " Syllabus der Pflanzenfamilien", and, as a last major contribution (with Hans Kastner) of Gewurze (19 ...

Botanist
Botany, also called plant science (or plant sciences), plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word (') meaning " pasture", "herbs" " grass", or "fodder"; is in turn derived from (), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syllabus Der Pflanzenfamilien
''Syllabus der Pflanzenfamilien'' (1892–) by Adolf Engler (1844–1930) is a complete revision of plant families down to generic level and often even further. As such it forms part of the Engler system of plant taxonomy. Engler's starting point was that of Eichler who had been the first to use phylogenetic principles, and reflected the new post-Darwinian perspective, although Engler himself did not think that his was. His modified Eichler schema first appeared in 1886 in his ''Guide to Breslau Botanic Garden'' (of which he was the director) and was expanded in his ''Syllabus'' in 1892. This reflected the new post-Darwinian perspective. Engler's ''Syllabus der Pflanzenfamilien'' first appeared in 1892 with the title ''Syllabus der Vorlesungen über specielle und medicinisch-pharmaceutische Botanik''. Many subsequent editions have appeared since, and it was continued after Engler's death in 1930. The most recent edition was the 13th in 2009. A number of references to the Engler ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. They include all forbs (flowering plants without a woody stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. The term "angiosperm" is derived from the Greek words ἀγγεῖον / ('container, vessel') and σπέρμα / ('seed'), meaning that the seeds are enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Angiosperms are distinguished from the other seed-producing plants, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the common ance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melchior System
The Melchior system, "a reference in all taxonomic courses", is a classification system detailing the taxonomic system of the Angiospermae according to A. Engler's ''Syllabus der Pflanzenfamilien'' (1964), also known as "modified or updated" Engler system. The collaborators in orders (and some families) were the following: * Hans Melchior in Casuarinales, Juglandales, Balanopales, Leitneriales, Salicales, Fagales, Urticales, Didiereaceae, Piperales, Aristolochiales, Guttiferales, Sarraceniales, Papaverales, Hydrostachyales, Podostemonales, Julianiales, Violales, Cucurbitales, Myrtiflorae, Umbelliflorae, Primulales, Tubiflorae, Plantaginales, Liliiflorae ''p. p.'', Spathiflorae and Microspermae. * G.

Balthasaria
''Balthasaria'' is a genus of plant in the family Pentaphylacaceae. They are found in Africa, within Burundi, Rwanda, Tanzania, Uganda and Zaïre. Originally the species was called ''Melchiora'' by Clarence Emmeren Kobuski in 1956 in honour of Hans Melchior (1894 - 1984) a German botanist, but this was deemed incorrect by IPNI, as Kobuski should have formed his name by adding 'ia' to Melchior, becoming an illegitimate homonym for the fungal genus ''Melchioria'' published by Penzig and Saccardo in 1897, in honor of Melchior Treub. Botanist Bernard Verdcourt Bernard Verdcourt (20 January 1925 – 25 October 2011) was a biologist and taxonomist, most widely known as a botanist and latterly an honorary research fellow at the Royal Botanic Gardens, Kew in London. Prior to coming to Kew in 1964, he ... noted "Since a new name is inevitable I have chosen one based on one of the other 'wise men", ie, Balthazar.

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, '' Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia l ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below 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 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 of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

International Association For Plant Taxonomy
The International Association for Plant Taxonomy (IAPT) is an organization established to promote an understanding of plant biodiversity, facilitate international communication of research between botanists, and oversee matters of uniformity and stability in plant names. The IAPT was founded on July 18, 1950, at the Seventh International Botanical Congress in Stockholm, Sweden. The IAPT headquarters is located in Bratislava, Slovakia. Its president, since 2017, is Patrick S. Herendeen of the Chicago Botanic Garden; vice-president is Gonzalo Nieto Feliner of the Real Jardín Botánico, Madrid; and secretary-general is Karol Marhold of the Plant Science and Biodiversity Centre, Slovak Academy of Sciences, Bratislava. Both the taxonomic journal ''Taxon'' and the series ''Regnum Vegetabile'' are published by the IAPT. The latter series includes the ''International Code of Nomenclature for algae, fungi, and plants'', ''Index Nominum Genericorum'', and ''Index Herbariorum''. Purpo ...
