Coleus Fredericii
''Coleus fredericii'', synonym ''Plectranthus welwitschii'', is a species of plant in the family Lamiaceae. The epithet is also spelt ''frederici''. The species was originally described by John Isaac Briquet in 1894, as ''Neomuellera welwitschii''. It was transferred to the genus ''Plectranthus'' by Leslie Codd in 1972. A 2018 phylogenetic study showed that ''Plectranthus'', as then circumscribed was not monophyletic, and so revived the then defunct genus ''Coleus ''Coleus'' is a genus of annual or perennial herbs or shrubs, sometimes succulent, sometimes with a fleshy or tuberous rootstock, found in the Old World tropics and subtropics.

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 le ...

Lamiaceae
The Lamiaceae ( ) or Labiatae are a family of flowering plants commonly known as the mint, deadnettle or sage family. Many of the plants are aromatic in all parts and include widely used culinary herbs like basil, mint, rosemary, sage, savory, marjoram, oregano, hyssop, thyme, lavender, and perilla, as well as other medicinal herbs such as catnip, salvia, bee balm, wild dagga, and oriental motherwort. Some species are shrubs, trees (such as teak), or, rarely, vines. Many members of the family are widely cultivated, not only for their aromatic qualities, but also their ease of cultivation, since they are readily propagated by stem cuttings. Besides those grown for their edible leaves, some are grown for decorative foliage. Others are grown for seed, such as ''Salvia hispanica'' (chia), or for their edible tubers, such as ''Plectranthus edulis'', ''Plectranthus esculentus'', '' Plectranthus rotundifolius'', and '' Stachys affinis'' (Chinese artichoke). Many are also grown orn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plectranthus
''Plectranthus'' is a genus of about 85 species of flowering plants from the sage family, Lamiaceae, found mostly in southern and tropical Africa and Madagascar. Common names include spur-flower. ''Plectranthus'' species are herbaceous perennial plants, rarely annuals or soft-wooded shrubs, sometimes succulent; sometimes with a tuberous base. Several species are grown as ornamental plants. The cultivar = 'Plepalila' has received the Royal Horticultural Society's Award of Garden Merit. Recent phylogenetic analysis found ''Plectranthus'' to be paraphyletic with respect to ''Coleus'', ''Solenostemon'', ''Pycnostachys'' and ''Anisochilus''. The most recent treatment of the genus resurrected the genus ''Coleus'', and 212 names were changed from combinations in ''Plectranthus'', ''Pycnostachys'' and ''Anisochilus''. ''Equilabium'' was segregated from ''Plectranthus'', after phylogenetic studies supported its recognition as a phylogenetically distinct genus. Etymology The wo ...

Leslie Codd
Leslie Edward Wostall Codd (16 September 1908 in Vants Drift, Dundee, District, Natal – 2 March 1999 in Pretoria), was a South African plant taxonomist. Life Codd was born in 1908. He attended the Natal University College where he obtained an M.Sc in 1928. He continued his studies at Cambridge University in 1929, and the ''Imperial College of Tropical Agriculture'' in Trinidad in 1930, where he met his future wife, Cynthia. He worked with the Department of Agriculture in British Guiana between 1931 and 1936. In 1937 he was appointed to the Pasture Research Section of the Department of Agriculture in Pretoria. In 1941 he was awarded a D.Sc degree by the University of South Africa. In 1945 he assumed the post of Officer-in-Charge at the ''Prinshof Experiment Station'' in the ''Division of Botany'', where he was involved with the selection, growing and testing of pasture grasses. At the same time he was in charge of the ''Botanical Survey of South Africa.'' While stationed at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phylogenetics
In biology, phylogenetics (; from Greek language, Greek wikt:φυλή, φυλή/wikt:φῦλον, φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, Protein, protein Amino acid, amino acid sequences, or Morphology (biology), morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. If we determine that species X, Y, and Z belong in Genus A, and species T, U, V, and W belong in Genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecular phylogenetics ...

Monophyly
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have taken ...

Coleus
''Coleus'' is a genus of annual or perennial herbs or shrubs, sometimes succulent, sometimes with a fleshy or tuberous rootstock, found in the Old World tropics and subtropics. The relationship among the genera ''Coleus'', '' Solenostemon'' and '' Plectranthus'' has been confused. ''Coleus'' and ''Solenostemon'' were sunk into ''Plectranthus'', but recent phylogenetic analysis found ''Plectranthus'' to be paraphyletic with respect to other related genera in the subtribe Plectranthinae. The most recent taxonomic treatment of the genus resurrected ''Coleus'', and 212 names were changed from combinations in ''Plectranthus'', ''Pycnostachys'' and ''Anisochilus''. ''Equilabium'' was segregated from ''Plectranthus'', after phylogenetic studies supported its recognition as a phylogenetically distinct genus. ''Coleus'' are cultivated as ornamental plants, particularly ''Coleus scutellarioides'' (syns. ''Coleus blumei'', ''Plectranthus scutellarioides''), which is popular as a garden p ...

International Plant Names Index
The International Plant Names Index (IPNI) describes itself as "a database of the names and associated basic bibliographical details of seed plants, ferns and lycophytes." Coverage of plant names is best at the rank of species and genus. It includes basic bibliographical details associated with the names. Its goals include eliminating the need for repeated reference to primary sources for basic bibliographic information about plant names. The IPNI also maintains a list of standardized author abbreviations. These were initially based on Brummitt & Powell (1992), but new names and abbreviations are continually added. Description IPNI is the product of a collaboration between The Royal Botanic Gardens, Kew (Index Kewensis), The Harvard University Herbaria (Gray Herbarium Index), and the Australian National Herbarium ( APNI). The IPNI database is a collection of the names registered by the three cooperating institutions and they work towards standardizing the information. The stan ...
