Suksdorfia
''Suksdorfia'' is a genus in the family Saxifragaceae. It has only two accepted species, '' Suksdorfia alchemilloides'' and '' Suksdorfia violacea'', native to central South America and northwestern North America, respectively. Asa Gray named the genus ''Suksdorfia'' after Wilhelm Nikolaus Suksdorf, a mostly self-taught German botanist who came to the United States at age eight and found the species ''S. violacea'' in the northwestern United States. ''S. violacea'' is the type species In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specime ... for this genus. Since the International Rules of Botanical Nomenclature of 1906, the genus name ''Suksdorfia'' Gray, published in 1879, has been conserved against the earlier name ''Hemieva'' Raf., which had been published in 1837 with the type sp ...

Suksdorfia Violacea
''Suksdorfia violacea'' is an uncommon species of herbaceous flowering plant in the saxifrage family known by the common name violet suksdorfia. In 1879 Asa Gray named the genus ''Suksdorfia'' after Wilhelm Nikolaus Suksdorf who had first collected a specimen of ''S. violacea'' in 1878 near Mount Adams-White Salmon, Washington and sent it to Gray for assistance in classifying it. Gray and Suksdorf had a long and close working relationship, and Gray initially identified and named various species found by Suksdorf. Its conservation status has been rated by NatureServe as "G4 – Apparently Secure". Taxonomy ''Suksdorfia violacea'' is the type species for this genus and Gray named it after Suksdorf. The genus name ''Hemieva'' Raf. was published earlier than ''Suksdorfia'', but was less well known, and ''Suksdorfia'' is now a conserved name. Therefore, ''Hemieva violacea'', although correct when it was published in 1896 is no longer the correct name for this species. Ecology ' ...

Wilhelm Nikolaus Suksdorf
Wilhelm Nikolaus Suksdorf (September 15, 1850 – October 3, 1932) was a German–American botanist who specialized in the flora of the Pacific Northwest. He was largely self-taught and is considered one of the top three self-taught botanists of his era for the Pacific Northwest, alongside Thomas Jefferson Howell and William Conklin Cusick. Early life Suksdorf was born on September 15, 1850 in the small village of Dransau, along the eastern border of Schleswig, but it is often listed as the nearby large city of Kiel, Germany. His parents were Detlev Suksdorf, a tenant farmer, and Louise Schröder Suksdorf, who had nine children. Two of these children were girls who died young. The seven boys all lived well into adulthood. Suksdorf was the 6th child and 2nd-youngest son. At age eight, Suksdorf's family moved to Davenport, Iowa, where he lived until 1874. After a few years as a tenant farmer, Suksdorf's father bought 100 acres of unbroken prairie, where the family lived an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asa Gray
Asa Gray (November 18, 1810 – January 30, 1888) is considered the most important American botanist of the 19th century. His ''Darwiniana'' was considered an important explanation of how religion and science were not necessarily mutually exclusive. Gray was adamant that a genetic connection must exist between all members of a species. He was also strongly opposed to the ideas of hybridization within one generation and special creation in the sense of its not allowing for evolution. He was a strong supporter of Darwin, although Gray's theistic evolution was guided by a Creator. As a professor of botany at Harvard University for several decades, Gray regularly visited, and corresponded with, many of the leading natural scientists of the era, including Charles Darwin, who held great regard for him. Gray made several trips to Europe to collaborate with leading European scientists of the era, as well as trips to the southern and western United States. He also built an extensive n ...

Saxifragaceae
Saxifragaceae is a family of herbaceous perennial flowering plants, within the core eudicot order Saxifragales. The taxonomy of the family has been greatly revised and the scope much reduced in the era of molecular phylogenetic analysis. The family is divided into ten clades, with about 640 known species in about 35 accepted genera. About half of these consist of a single species, but about 400 of the species are in the type genus '' Saxifraga''. The family is predominantly distributed in the northern hemisphere, but also in the Andes in South America. Description Species are herbaceous perennials (rarely annual or biennial), sometimes succulent or xerophytic, often with perennating rhizomes. The leaves are usually basally aggregated in alternate rosettes, sometimes on inflorescence stems. They are usually simple, rarely pinnately or palmately compound. Their margins may be entire, deeply lobed, cleft, crenate or dentate and petiolate with stipules. The inflorescences ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plants Of The World Online
Plants of the World Online (POWO) is an online database published by the Royal Botanic Gardens, Kew. It was launched in March 2017 with the ultimate aim being "to enable users to access information on all the world's known seed-bearing plants by 2020". The initial focus was on tropical African Floras, particularly Flora Zambesiaca, Flora of West Tropical Africa and Flora of Tropical East Africa. The database uses the same taxonomical source as Kew's World Checklist of Selected Plant Families, which is the International Plant Names Index, and the World Checklist of Vascular Plants (WCVP). POWO contains 1,234,000 global plant names and 367,600 images. See also *Australian Plant Name Index The Australian Plant Name Index (APNI) is an online database of all published names of Australian vascular plants. It covers all names, whether current names, synonyms or invalid names. It includes bibliographic and typification details, informati ... * Convention on Biological Diversity * Wor ...

Adolf Engler
Heinrich Gustav Adolf Engler (25 March 1844 – 10 October 1930) was a German botanist. He is notable for his work on plant taxonomy and phytogeography, such as ''Die natürlichen Pflanzenfamilien'' (''The Natural Plant Families''), edited with Karl A. E. von Prantl. Even now, his system of plant classification, the Engler system, is still used by many herbaria and is followed by writers of many manuals and floras. It is still the only system that treats all 'plants' (in the wider sense, algae to flowering plants) in such depth. Engler published a prodigious number of taxonomic works. He used various artists to illustrate his books, notably Joseph Pohl (1864–1939), an illustrator who had served an apprenticeship as a wood-engraver. Pohl's skill drew Engler's attention, starting a collaboration of some 40 years. Pohl produced more than 33 000 drawings in 6 000 plates for ''Die naturlichen Pflanzenfamilien''. He also illustrated ''Das Pflanzenreich'' (1900–1953), ''Die P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

International Rules Of Botanical Nomenclature
The ''International Code of Nomenclature for algae, fungi, and plants'' (ICN) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all those "traditionally treated as algae, fungi, or plants".. It was formerly called the ''International Code of Botanical Nomenclature'' (ICBN); the name was changed at the International Botanical Congress in Melbourne in July 2011 as part of the ''Melbourne Code''. which replaced the ''Vienna Code'' of 2005. The current version of the code is the ''Shenzhen Code'' adopted by the International Botanical Congress held in Shenzhen, China, in July 2017. As with previous codes, it took effect as soon as it was ratified by the congress (on 29 July 2017), but the documentation of the code in its final form was not published until 26 June 2018. The name of the ''Code'' is partly capitalized and partly not. The lower-case for "algae, fungi, and plants" indica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conserved Name
A conserved name or ''nomen conservandum'' (plural ''nomina conservanda'', abbreviated as ''nom. cons.'') is a scientific name that has specific nomenclatural protection. That is, the name is retained, even though it violates one or more rules which would otherwise prevent it from being legitimate. ''Nomen conservandum'' is a Latin term, meaning "a name to be conserved". The terms are often used interchangeably, such as by the ''International Code of Nomenclature for Algae, Fungi, and Plants'' (ICN), while the ''International Code of Zoological Nomenclature'' favours the term "''conserved name''". The process for conserving botanical names is different from that for zoological names. Under the botanical code, names may also be "suppressed", ''nomen rejiciendum'' (plural ''nomina rejicienda'' or ''nomina utique rejicienda'', abbreviated as ''nom. rej.''), or rejected in favour of a particular conserved name, and combinations based on a suppressed name are also listed as “''nom. re ...

Flora Of The Americas
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
