Equilabium Jebel-marrae
''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 (pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''sporangium, microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...

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.

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 ...
