Biebersteinia Multifida
''Biebersteinia'' is a genus containing five species, of herbs in the flowering plant order Sapindales. They occur from East Mediterranean to West Siberia and Central Asia. They are normally stemless and have tuberous rhizomes.Armen Takhtajan In 1806, Christian Friedrich Stephan formed the genus ''Biebersteinia'', then in 1841 Endlicher converted it to a family status. This was the start of various changes to the genus. It was then placed in Geraniaceae by Pierre Edmond Boissier, in 1867, and changed by various botanists (including Knuth (1912), Thorne (1992), Cronquist (1981, 1988), Dahlgren (1989) and Takhtajan (1987 and 1997)). In 2007, molecular phylogenetic studies have given it a basal position within Sapindales. In the APG III system and in the Kubitzki system, it is placed in its own monogeneric family, Biebersteiniaceae, one of the few herbaceous members of Sapindales (the others being found in Rutaceae). The name refers to a German botanist Friedrich August ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adalbert Schnizlein
Adalbert Carl Friedrich Hellwig Conrad Schnizlein (15 April 1814, Feuchtwangen – 24 October 1868, Erlangen) was a German botanist and pharmacist. He is largely remembered for his work in the fields of plant taxonomy and phytogeography. Background He received training in pharmacy at Ansbach, afterwards becoming an assistant pharmacist in Nördlingen (1833). He later studied pharmacy at the University of Munich, earning his doctorate at the University of Erlangen in 1836. In 1845 he was habilitated in botany at Erlangen, where in 1850 he became an associate professor of botany and director of the botanical garden.Biography @ Deutsche Biographie. Contributions His most extensive work, "Iconographia familiarum naturalium regni vegetabilis" (1843–1870), was issued in four volumes.

Geraniaceae
Geraniaceae is a family of flowering plants placed in the order Geraniales. The family name is derived from the genus ''Geranium''. The family includes both the genus ''Geranium'' (the cranesbills, or true geraniums) and the garden plants called geraniums, which modern botany classifies as genus ''Pelargonium'', along with other related genera. The family comprises 830 species in five to seven genera. The largest genera are ''Geranium'' (430 species), ''Pelargonium'' (280 species) and ''Erodium'' (80 species). Description Geraniaceae are herbs or subshrubs. The ''Sarcocaulon'' are succulent, but other members of the family generally are not. Leaves are usually lobed or otherwise divided, sometimes peltate, opposite or alternate and usually have stipules. The flowers are generally regular, or symmetrical. They are hermaphroditic, actinomorphic (radially symmetrical, like in ''Geranium'') or slightly zygomorphic (with a bilateral symmetry, like in ''Pelargonium''). The calyx an ...

Friedrich August Marschall Von Bieberstein
Baron Friedrich August Marschall von Bieberstein (30 July 1768 in Stuttgart – 28 June 1826 in Merefa) was an early explorer of the flora and archeology of the southern portion of Imperial Russia, including the Caucasus and Novorossiya. He compiled the first comprehensive flora catalogue of the Crimeo-Caucasian region. Origin Friedrich Marschall von Bieberstein was the son of a Colonel from Württemberg 'Conrad Otto Christoph Freiherr Marschall von Bieberstein' (17 March 1726 – 25 May 1796), and his wife 'Johanna Theresia Henriette' née Wolf from Ludwigsburg (21 December 1738 – 1783). They married on 21 September 1761. The 'Marschall von Bieberstein' family can trace its origins back over 800 years to the region today called Saxony in eastern Germany. The current family name derives from Bieberstein castle near Dresden. He had three brothers, Carl Wilhelm Marschall von Bieberstein (1764–1817), who was from 1792 worked in Baden, then in 1800 became President of the Priv ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opin ...

Monotypic Taxon
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. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopod ...

Kubitzki System
The Kubitzki system is a system of plant taxonomy devised by Klaus Kubitzki, and is the product of an ongoing survey of vascular plants, entitled ''The Families and Genera of Vascular Plants'', and extending to 15 volumes in 2018. The survey, in the form of an encyclopedia, is important as a comprehensive, multivolume treatment of the vascular plants, with keys to and descriptions of all families and genera, mostly by specialists in those groups. The Kubitzki system served as the basis for classification in ''Mabberley's Plant-Book'', a dictionary of the vascular plants. Mabberley states, in his Introduction on page xi of the 2008 edition, that the Kubitzki system "has remained the standard to which other literature is compared". In ordinal and family arrangements, the classification system in the initial angiosperm volumes closely resembles the Dahlgren system in Monocots and the Cronquist system in Dicots, but later volumes have been influenced by recent molecular phylog ...

APG III System
The APG III system of flowering plant classification is the third version of a modern, mostly molecular-based, system of plant taxonomy being developed by the Angiosperm Phylogeny Group (APG). Published in 2009, it was superseded in 2016 by a further revision, the APG IV system. Along with the publication outlining the new system, there were two accompanying publications in the same issue of the Botanical Journal of the Linnean Society: * The first, by Chase & Reveal, was a formal phylogenetic classification of all land plants (embryophytes), compatible with the APG III classification. As the APG have chosen to eschew ranks above order, this paper was meant to fit the system into the existing Linnaean hierarchy for those that prefer such a classification. The result was that all land plants were placed in the class Equisetopsida, which was then divided into 16 subclasses and a multitude of superorders. * The second, by Haston ''et al.'', was a linear sequence of families follo ...

Basal (phylogenetics)
In phylogenetics, basal is the direction of the ''base'' (or root) of a rooted phylogenetic tree or cladogram. The term may be more strictly applied only to nodes adjacent to the root, or more loosely applied to nodes regarded as being close to the root. Note that extant taxa that lie on branches connecting directly to the root are not more closely related to the root than any other extant taxa. While there must always be two or more equally "basal" clades sprouting from the root of every cladogram, those clades may differ widely in taxonomic rank, species diversity, or both. If ''C'' is a basal clade within ''D'' that has the lowest rank of all basal clades within ''D'', ''C'' may be described as ''the'' basal taxon of that rank within ''D''. The concept of a 'key innovation' implies some degree of correlation between evolutionary innovation and diversification. However, such a correlation does not make a given case predicable, so ancestral characters should not be imputed to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Bror Eric Dahlgren
Bror is a Scandinavian masculine given name which simply means 'brother'. The name has been found as early as in runestones in the form Brodhir. The name form Bror is known since the year 1536. It is also used heavily in a colloquial sense in the city of Belfast. Bror used to be a name that was never given to the oldest son of a family. From the 19th century, the literal meaning of the name has not been as important and the name could be given to any son. Bror was a very common name in Sweden during the first decades of the 20th century. It has since been less common. It is also in fairly common use in Denmark and Norway. Name day: 5 October in Sweden, 9 January in Swedish speaking Finland, 20 May in Norway since 2014.

Arthur John Cronquist
Arthur John Cronquist (March 19, 1919 – March 22, 1992) was an American biologist, botanist and a specialist on Compositae. He is considered one of the most influential botanists of the 20th century, largely due to his formulation of the Cronquist system as well as being the primary co-author to the Flora of the Pacific Northwest, still the most up to date flora for three northwest U.S. States to date. Two plant genera in the aster family have been named in his honor. These are ''Cronquistia'', a possible synonym of '' Carphochaete'', and ''Cronquistianthus'', which is sometimes included as a group within ''Eupatorium''. The former was applied by R.M. King and the latter by him and Harold E. Robinson. Life Arthur Cronquist was born on March 19, 1919, in San Jose, California, but he grew up outside of Portland, Oregon, as well as in Pocatello, Idaho. His parents divorced when he was young and he and his older sister were brought up by his mother, who worked for the Union ...
