Equilabium
''Equilabium'' is a genus of flowering plants in the family Lamiaceae. It was split off from the genus ''Plectranthus'' in 2018 as the result of a molecular phylogenetic study. Most species are native to Africa, with two found in the Indian subcontinent. Description Species of ''Equilabium'' are herbaceous or soft-wooded shrubs, rarely woody shrubs. The herbaceous species may be annual or perennial. The leaves are opposite. The inflorescences are " thryses" – compound structures in which the flowers are arranged on secondary branches. Individual flowers have stalks (pedicels). The sepals form a two-lipped funnel shape, the upper lip having four lobes, the lower lip one lobe. The petals form a two-lipped tube, with an S-shaped basal portion. There are four stamens, whose filaments are not fused together. The style is divided into two parts (bifid). The nutlets are ovoid. ''Equilabium'' and ''Plectranthus'' species are distinguished from ''Coleus'' by having the stem (pedicel) o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Capitanopsis
''Capitanopsis'' is a genus of plants in the family Lamiaceae, first described in 1916. It contains six known species, all endemic to Madagascar. Taxonomy Phylogeny In 2019, Paton et al. published a summary cladogram for the subtribe Plectranthinae, based on an earlier 2018 study. The formerly recognized monotypic genera ''Dauphinea'', ''Madlabium'' and ''Perrierastrum'' were found to form a clade with three species placed in ''Capitanopsis'', so were transferred to that genus. ''Capitanopsis'' was a sister of the newly established genus ''Equilabium''. Species Paton et al. (2018) recognize six species: * ''Capitanopsis albida'' (Baker) Hedge * ''Capitanopsis angustifolia'' (Moldenke) Capuron * '' Capitanopsis brevilabra'' (Hedge) Mwany., A.J.Paton & Culham, syn. ''Dauphinea brevilabra'' * ''Capitanopsis cloiselii'' S.Moore * ''Capitanopsis magentea'' (Hedge) Mwany., A.J.Paton & Culham, syn.

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''.

Herbaceous Plant
Herbaceous plants are vascular plants that have no persistent woody stems above ground. This broad category of plants includes many perennials, and nearly all annuals and biennials. Definitions of "herb" and "herbaceous" The fourth edition of the ''Shorter Oxford English Dictionary'' defines "herb" as: #"A plant whose stem does not become woody and persistent (as in a tree or shrub) but remains soft and succulent, and dies (completely or down to the root) after flowering"; #"A (freq. aromatic) plant used for flavouring or scent, in medicine, etc.". (See: Herb) The same dictionary defines "herbaceous" as: #"Of the nature of a herb; esp. not forming a woody stem but dying down to the root each year"; #"BOTANY Resembling a leaf in colour or texture. Opp. scarious". Botanical sources differ from each other on the definition of "herb". For instance, the Hunt Institute for Botanical Documentation includes the condition "when persisting over more than one growing season, the parts o ...

Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...

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] |
Molecular Phylogenetics
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.
