Thermopsideae
The tribe (biology), tribe Sophoreae is one of the subdivisions of the plant family (biology), family Fabaceae. Traditionally this tribe has been used as a wastebasket taxon to accommodate genera of Faboideae which exhibit actinomorphic, rather than zygomorphic floral symmetry and/or incompletely differentiated petals and free stamens. Various morphological and molecular phylogeny, molecular analyses indicated that Sophoreae as traditionally circumscription (taxonomy), circumscribed was polyphyly, polyphyletic. This led to a re-circumscription of Sophoreae, which resulted in the transfer of many genera to other tribes (Amburaneae, Angylocalyceae, Baphieae, Camoensieae, the Cladrastis clade, ''Cladrastis'' clade, Exostyleae, Leptolobieae, Ormosieae, Podalyrieae, and the Vataireoids). This also necessitated the inclusion of two former tribes, Euchresteae and Thermopsideae, in the new definition of Sophoreae. Tribe Sophoreae, as currently circumscribed, consistently forms a monophyly, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Faboideae
The Faboideae are a subfamily of the flowering plant family Fabaceae or Leguminosae. An acceptable alternative name for the subfamily is Papilionoideae, or Papilionaceae when this group of plants is treated as a family. This subfamily is widely distributed, and members are adapted to a wide variety of environments. Faboideae may be trees, shrubs, or herbaceous plants. Members include the pea, the sweet pea, the laburnum, and other legumes. The pea-shaped flowers are characteristic of the Faboideae subfamily and root nodulation is very common. Genera The type genus, ''Faba'', is a synonym of ''Vicia'', and is listed here as ''Vicia''. *''Abrus'' *''Acmispon'' *''Acosmium'' *'' Adenocarpus'' *'' Adenodolichos'' *'' Adesmia'' *'' Aenictophyton'' *''Aeschynomene'' *'' Afgekia'' *''Aganope'' *'' Airyantha'' *''Aldina'' *''Alexa'' *''Alhagi'' *'' Alistilus'' *'' Almaleea'' *'' Alysicarpus'' *'' Amburana'' *''Amicia'' *'' Ammodendron'' *'' Ammopiptanthus'' *'' Ammothamnus'' *'' ...

Sophora Tetraptera
''Sophora tetraptera'', commonly known as large-leaved kōwhai, grows naturally only in the central east of the North Island in New Zealand. ''S. tetraptera'' has larger more widely spaced leaves than the other seven species of kōwhai. Etymology The generic name, ''Sophora'' derives from the Arabic, ''sophora'' (any tree with pea-flowers), and the specific epithet, ''tetraptera'', comes from the Greek (four-winged) and refers to the fruits.

Polyphyly
A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. ource for pronunciation./ref> It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthetic plants, and edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major revisions of the classification schemes. Researchers concerned more with ecology than with system ...

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 ...

Taxon (journal)
''Taxon'' is a bimonthly peer-reviewed scientific journal covering plant taxonomy. It is published by Wiley on behalf of the International Association for Plant Taxonomy, of which it is the official journal. It was established in 1952 and is the only place where nomenclature proposals and motions to amend the International Code of Nomenclature for algae, fungi, and plants (except for the rules concerning fungi) can be published. The editor-in-chief is Dirk C. Albach (University of Oldenburg). Abstracting and indexing The journal is abstracted and indexed in: According to the ''Journal Citation Reports'', the journal has a 2020 impact factor The impact factor (IF) or journal impact factor (JIF) of an academic journal is a scientometric index calculated by Clarivate that reflects the yearly mean number of citations of articles published in the last two years in a given journal, as i ... of 2.817.

Vataireoids
The vataireoids are an early-branching monophyletic clade of the flowering plant subfamily Faboideae (or Papilionaceae) that are mostly found in northern South America, primarily Brazil. Description This clade is composed of four genera, two of which were traditionally assigned to the tribe Dalbergieae ('' Vatairea'' and '' Vataireopsis'') and two of which were traditionally assigned to the tribe Sophoreae ('' Luetzelburgia'' and ''Sweetia''), mainly on the basis of flower morphology. However, recent molecular phylogenetic analyses circumscribed these four genera into a strongly supported monophyletic clade. The name of this clade is informal and is not assumed to have any particular taxonomic rank like the names authorized by the ICBN or the ICPN. The clade is defined as:"The most inclusive crown clade containing ''Sweetia fruticosa'' Spreng. 1825 and ''Vatairea guianensis'' Aubl. but not ''Andira inermis'' (W. Wright) DC., '' Zollernia ilicifolia'' (Brongn.) Vogel 1837, or ''A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Podalyrieae
The tribe Podalyrieae is one of the subdivisions of the plant family Fabaceae. Description The Podalyrieae arose 30.5 ± 2.6 million years ago (in the Oligocene) in the fynbos ( Cape Floristic Region) of South Africa and is still mostly found there. All members of the tribe exhibit either nonsprouting or sprouting fire survival strategies. Many species are pollinated by insects, especially carpenter bees, while others are pollinated by sunbirds or rodents. The members of this tribe consistently form a monophyletic clade in molecular phylogenetic analyses. The tribe does not currently have a node-based definition, but several morphological synapomorphies have been identified: "imparipinnately compound leaves, axillary racemose inflorescences, carboxylic acid esters of quinolizidine alkaloids, and the isoflavone 3′-hydroxydaidzein as a major seed flavonoid" as well as "strongly reduced or absent bracteoles and the occurrence of persistent antipodals in the female gametophy ...

Ormosieae
The tribe Ormosieae is one of the subdivisions of the plant family Fabaceae, primarily found in tropical regions of the Americas, but also in southeast Asia and northern Australia. The members of this tribe were formerly included in tribe Sophoreae, but were recently circumscribed into a new tribe. The members of this tribe consistently form a monophyletic clade in molecular phylogenetic analyses. The tribe does not currently have a node-based definition, but morphological synapomorphies have been tentatively identified: "mostly dehiscent pods with woody valves" and "tufts of minute colleter-like glands in the axils of bract and bracteoles". Like other genistoids, members of tribe Ormosieae are known to produce quinolizidine Quinolizidine (norlupinane, octahydro-2''H''-quinolizine) is a nitrogen-containing heterocyclic compound. Some alkaloids (e.g. cytisine and sparteine) are derivatives of quinolizidine. Quinolizidine alkaloids Quinolizidine alkaloids, such as ... alkal ...

Leptolobieae
Leptolobieae is a Neotropical, early-branching monophyletic clade of the flowering plant subfamily Faboideae or Papilionaceae that are mostly found in South America. Description This tribe is composed of five genera, two of which were originally included in the genus ''Acosmium'' (''Guianodendron'' and ''Leptolobium'') and one of which was originally assigned to the genus ''Diplotropis'' (''Staminodianthus''). All of these genera were traditionally included in the tribe Sophoreae. However, recent molecular phylogenetic analyses resolved these five genera into a strongly-supported monophyletic clade, which warranted the reinstatement of the tribe Leptolobieae. A potential morphological synapomorphy for the tribe is: "tufts of minute colleter-like glands in the axils of bract and bracteoles".

Exostyleae
The tribe Exostyleae is an early-branching monophyletic clade of the flowering plant subfamily Faboideae (or Papilionaceae) that are mostly found in Neotropical rainforests. Description This clade is composed of 6 genera, most of which were traditionally assigned to the tribe Swartzieae. However, recent molecular phylogenetic analyses circumscribed these six genera into a strongly supported monophyletic clade. Synapomorphic traits that unite the members of this clade include non-papilionate flowers, "serrate and sometimes spinescent leaflet or leaf margins, standard position variable in the floral bud, basifixed anthers, and drupaceous fruits". They are also united by wood anatomy, sharing an "uncommon presence of crystals in ray cells", and floral ontogeny, sharing "unidirectional initiation of five sepals, simultaneous initiation of petals, and nusual antepetalous stamens initiating before the antesepalous ones."

Cladrastis Clade
The ''Cladrastis'' clade is a monophyletic clade of the flowering plant subfamily Faboideae (or Papilionaceae) that is found in eastern Asia and southern North America. It is consistently resolved in molecular phylogenies and is sister to the Meso-Papilionoideae. Evidence for the existence of this clade was first proposed based on morphological (floral), cytological, and biochemical evidence. It is predicted to have diverged from the other legume lineages 47.4±2.6 million years ago (in the Eocene). Description This clade is composed of three genera: ''Cladrastis'', the monotypic ''Pickeringia'', and ''Styphnolobium''. Fossils of species of ''Cladrastis'' and ''Styphnolobium'' have been discovered. The name of this clade is informal and is not assumed to have any particular taxonomic rank like the names authorized by the ICBN or the ICPN. The clade is defined as:"The most inclusive crown clade containing ''Cladrastis kentukea'' (Dum. Cours.) Rudd 1971 but not ''Dermatophyllum s ...
