Leucospermum Conocarpodendron
''Leucospermum conocarpodendron'' is the largest species of the genus ''Leucospermum'', reaching almost tree-like proportions of high with a firm trunk that is covered in a thick layer of cork that protects it from most fires. It has greyish or green narrow or broad inverted egg-shaped leaves with three to ten teeth near the tip and large yellow flowerheads, with firm, bent, yellow styles that stick far beyond the rest of the flower and give the impression of a pincushion. It is commonly known as the tree pincushion in English or goudsboom in Afrikaans. They naturally occur near Cape Town, South Africa. Two subspecies are distinguished. ''L. conocarpodendron'' subsp. ''conocarpodendron'', that has greyish leaves because they have a covering of felty hairs. ''L. conocarpodendron'' subsp. ''viridum'', has green leaves that lack felty hairs. Flowers can be found between August and December. Description ''L. conocarpodendron'' is an evergreen large shrub of high and in diameter ...

Leucospermum
''Leucospermum'' commonly known as pincushions, is a genus of evergreen upright, sometimes creeping shrubs that is assigned to the Proteaceae, with currently 48 known species. The shrubs mostly have a single stem at their base, but some species sprout from an underground rootstock, from which the plant can regrow after fire has killed the above ground biomass. In a larger group of species, specimens are killed by fire, and their survival depends on the seeds. In all species, seeds are collected by ants, which take them to their underground nests to feed on their elaiosome, ant breads, a seed dispersal strategy known as myrmecochory. This ensures that the seeds do not burn, so new plants can grow from them. ''Leucospermum'' species mostly have seated, simple, mostly leathery, often softly hairy leaves, set in a spiral, with entire margins or more often, with 3–17 blunt teeth with thickened, bony tips, and without stipules at their foot. The flowers are organised with many togeth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Combinatio Nova
In biological taxonomy, a combinatio nova (abbreviated comb. nov. or n. comb.) refers to the formal renaming of an organism's scientific name when it is transferred to a different genus, reclassified within a different species, or its taxonomic rank is altered. Unlike the naming of a new species (), a ''combinatio nova'' does not describe a previously unknown organism but reorganizes an existing name to reflect updated understanding of its relationships or classification. For example, when a species is moved to a new genus, its specific epithet is retained and combined with the new genus name, forming the new combination. This process ensures consistency and accuracy in naming while adhering to the rules established by nomenclature codes. The concept of ''combinatio nova'' plays a vital role in maintaining the stability and traceability of scientific names as taxonomic classifications evolve. Creating a valid ''combinatio nova'' requires proper citation of the original name, kno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Jacob Reichard
Johann Jacob Reichard (7 August 1743 in Frankfurt – 21 January 1782 in Frankfurt) was a German physician and botanist. He studied medicine, philosophy and natural sciences at the University of Göttingen, receiving his doctorate in 1768. While working as a physician in his hometown, he carried out investigations of flora native to the Frankfurt am Main area, publishing ''Flora Moeno-Francofurtana'' (2 volumes, 1772–78) as a result. Beginning in 1773, he served as chief physician at the Senckenburg Foundation, in which capacity, he was in charge of its library, botanical gardens and chemistry laboratory.Plett - Schmidseder / edited by Dictionary of German ...

Species Plantarum
' (Latin for "The Species of Plants") is a book by Carl Linnaeus, originally published in 1753, which lists every species of plant known at the time, classified into genus, genera. It is the first work to consistently apply binomial nomenclature, binomial names and was the starting point for the botanical nomenclature, naming of plants. Publication ' was published on 1 May 1753 by Laurentius Salvius in Stockholm, in two volumes. A second edition was published in 1762–1763, and a third edition in 1764, although this "scarcely differed" from the second. Further editions were published after Linnaeus' death in 1778, under the direction of Karl Ludwig Willdenow, the director of the Berlin-Dahlem Botanical Garden and Botanical Museum, Berlin Botanical Garden; the fifth edition was titled "fourth edition" and was published by Willdenow in four volumes, 1798 (1), 1800 (2), 1801 (31), 1803 (32), 1804 (33), 1805 (41), 1806 (42), rather than the dates printed on the volumes themselves. ...

Validly Published Name
In botanical nomenclature, a validly published name is a name that meets the requirements in the ''International Code of Nomenclature for algae, fungi, and plants'' (''ICN'') for valid publication. Valid publication of a name represents the minimum requirements for a botanical name to exist: terms that appear to be names but have not been validly published are referred to in the ''ICN'' as "designations". A validly published name may not satisfy all the requirements to be '' legitimate''. It is also not necessarily the correct name for a particular taxon and rank. Names that are not valid by ICN standards (''nomen invalidum'', ''nom. inval.'') are sometimes in use. This may occur when a taxonomist finds and recognises a taxon and thinks of a name, but delays publishing it in an adequate manner. A common reason to delay valid publication is that a taxonomist intends to write a ''magnum opus'' that provides an overview of the group, rather than a series of small papers. Another re ...

Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist 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 the son of a curate and was born in Råshult, in the countryside of Småland, 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 the 1750s and 1760s, he co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binominal Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (often shortened to just "binomial"), a binomen, name, or a scientific name; more informally, it is also called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called nomenclature, with an "n" before the "al" in "binominal", which is a typographic error, meaning "two-name naming system". The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Hom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herman Boerhaave
Herman Boerhaave (, 31 December 1668 – 23 September 1738Underwood, E. Ashworth. "Boerhaave After Three Hundred Years." ''The British Medical Journal'' 4, no. 5634 (1968): 820–25. .) was a Dutch chemist, botanist, Christian humanist, and physician. He is sometimes regarded as the founder of clinical teaching and of the modern academic hospital along with Venetian physician Santorio Santorio (1561–1636). Boerhaave introduced the quantitative approach into medicine, along with his pupil Albrecht von Haller (1708–1777). He was the first to isolate the chemical urea from urine. He was the first physician to put thermometer measurements to clinical practice. His motto was ''Simplex veri sigillum'': 'Simplicity is the sign of the truth'. He is often hailed as the "Dutch Hippocrates". Biography Boerhaave was born at Voorhout near Leiden. The son of a Protestant pastor, in his youth Boerhaave studied for a divinity degree and wanted to become a preacher.Mendelsohn, p. 287 Af ...

John Ray
John Ray Fellow of the Royal Society, FRS (November 29, 1627 – January 17, 1705) was a Christian England, English Natural history, naturalist widely regarded as one of the earliest of the English parson-naturalists. Until 1670, he wrote his name as John Wray. From then on, he used 'Ray', after "having ascertained that such had been the practice of his family before him". He published important works on botany, zoology, and natural theology. His classification of plants in his ''Historia Plantarum (Ray book), Historia Plantarum'', was an important step towards modern Taxonomy (biology), taxonomy. Ray rejected the system of dichotomy, dichotomous division by which species were classified by repeated sub-division into groups according to a pre-conceived series of characteristics they have or have not, and instead classified plants according to similarities and differences that emerged from observation. He was among the first to attempt a biological definition for the concept of ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Petiver
James Petiver () was a London apothecary, a fellow of the Royal Society as well as London's informal Temple Coffee House Botany Club, famous for his specimen collections in which he traded and study of botany and entomology. He corresponded with John Ray and Maria Sibylla Merian. Some of his notes and specimens were used by Carl Linnaeus, Carolus Linnaeus in descriptions of new species. The genus ''Petiveria'' was named in his honour by Charles Plumier. His collections were bought by Sir Hans Sloane and became a part of the Natural History Museum, London, Natural History Museum. Life Born somewhere between 1663 and 1665 in Hillmorton, Warwickshire to James (baptism record from Hillmorton has "Pettyfer", 22 February 1635) and Mary née Elborow, the family moved to London soon after where his father became a haberdasher. After the death of his father in 1676, Petiver was sent to Rugby Free School, sponsored by his maternal grandfather Richard Elborow. Petiver later stated that "I ha ...

Leonard Plukenet
Leonard Plukenet (1641–1706) was an English botanist, Royal Professor of Botany and gardener to Queen Mary. Biography Plukenet published ''Phytographia'' (London, 1691–1696) in four parts in which he described and illustrated rare exotic plants. It is a copiously illustrated work of more than 2 700 figures and is frequently cited in books and papers from the 17th century to the present. He collaborated with John Ray in the second volume of ''Historia Plantarum'' (London, 1686–1704).
