Eremothamnus
''Eremothamnus marlothianus'' is a species of shrub in the family Asteraceae, the only species in the genus ''Eremothamnus''. It is native to the coastal desert of Namibia. It is a small shrub with spiny leaves. Taxonomy and systematics The genus ''Eremothamnus'' was erected in 1889 by Otto Hoffmann, when he named its only species, ''Eremothamnus marlothianus''.Otto Hoffmann. 1889. "Plantae Marlothianae. Ein Beitrag zur Kentniss der Flora Südafrikas" ''Botanische Jarhbücher für Systematik, Pflanzengeschichte und Pflanzengeographie'' 10:278. The specific epithet is for Rudolf Marloth (1855–1931), a South African botanist, pharmacist, and analytical chemist. The generic name is derived from the Greek words ''eremos'' and ''thamnos''. Hoffmann did not give an etymology for the name and it has been supposed that it means "solitary shrub",Umberto Quattrocchi. 2000. ''CRC World Dictionary of Plant Names'' volume II, page 929.

Plantae
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost ...

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.

Tribe (biology)
In biology, a tribe is a taxonomic rank above genus, but below family (biology), family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxonomic ranks from genus upwards are capitalized, including both tribe and subtribe. In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Goat-antelope#Tribe Caprini, Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Scilloideae#Hyacintheae, Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology, the form ...

Biological Classification
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the ...

Sister Taxon
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same t ...

Supplementum Plantarum
', commonly abbreviated to ' or just ', and further abbreviated by botanists to ''Suppl. Pl.'', is a 1782 book by Carolus Linnaeus the Younger. Written entirely in Latin, it was intended as a supplement to the 1737 ' and the 1753 ', both written by the author's father, the "father of modern taxonomy", Carl Linnaeus. Its full title means: “''Supplement of Plants'', the 13th edition of ''A System of Vegetables'', the 6th edition of ''The Genera of Plants'' and the 2nd edition of ''The Species of Plants''”, listing the components of the book in order of presentation. The ''Systematis Vegetabilium'' (13th edition) in the title refers to ' as published in 1774 by Johan Andreas Murray, a student of Linnaeus, Sr. The cover page indicates that it was published in 1781, and it was long believed to have been published in October of that year. In 1976, however, Hermann Manitz used a letter written by Jakob Friedrich Ehrhart to show that it had in fact been published in April 1782. Furt ...

Prodromus Systematis Naturalis Regni Vegetabilis
''Prodromus Systematis Naturalis Regni Vegetabilis'' (1824–1873), also known by its standard botanical abbreviation ''Prodr. (DC.)'', is a 17-volume treatise on botany initiated by Augustin Pyramus de Candolle. De Candolle intended it as a summary of all known seed plants, encompassing taxonomy, ecology, evolution and biogeography. He authored seven volumes between 1824 and 1839, but died in 1841. His son, Alphonse de Candolle, then took up the work, editing a further ten volumes, with contributions from a range of authors. Volume 17 was published in October 1873. The fourth and final part of the index came out in 1874. The ''Prodromus'' remained incomplete, dealing only with dicotyledons. In the ''Prodromus'', De Candolle further developed his concept of families. Note that this system was published well before there were internationally accepted rules for botanical nomenclature. Here, a family is indicated as "ordo". Terminations for families were not what they are now. Neit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Classic
A classic is an outstanding example of a particular style; something of lasting worth or with a timeless quality; of the first or highest quality, class, or rank – something that exemplifies its class. The word can be an adjective (a ''classic'' car) or a noun (a ''classic'' of English literature). It denotes a particular quality in art, architecture, literature, design, technology, or other cultural artifacts. In commerce, products are named 'classic' to denote a long-standing popular version or model, to distinguish it from a newer variety. ''Classic'' is used to describe many major, long-standing sporting events. Colloquially, an everyday occurrence (e.g. a joke or mishap) may be described in some dialects of English as 'an absolute classic'. "Classic" should not be confused with ''classical'', which refers specifically to certain cultural styles, especially in music and architecture: styles generally taking inspiration from the Classical tradition, hence classicism ...
