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 ...

Pickeringia Montana
''Pickeringia'' is a monotypic genus of flowering plants in the legume family, Fabaceae. It was recently assigned to the unranked, monophyletic ''Cladrastis'' clade. It was named after the naturalist Charles Pickering. Its only species is ''Pickeringia montana'', which is known by the common name chaparral pea. It is endemic to California in the United States, where its distribution extends along the Coast Ranges to the Peninsular Ranges, as well as along the Sierra Nevada foothills. It is also known from Santa Cruz Island.Howard JL. 1992''Pickeringia montana''.In: Fire Effects Information System. USDA FS. Rocky Mountain Research Station, Fire Sciences Laboratory. It is one of very few legumes native to the chaparral habitat. Its nitrogen-fixing ability helps it thrive in rocky, sandy soil. The plant is also well-suited to a landscape of hills, slopes, and recently burned areas; its roots spread quickly and help anchor loose soil, preventing erosion. Description The chaparral p ...

Meso-Papilionoideae
Meso-Papilionoideae is a monophyletic clade of the flowering plant subfamily Faboideae (or Papilionoideae) that includes the majority of papilionoid legumes. This clade is consistently resolved in molecular phylogenies. It contains many agronomically important genera, including ''Arachis'' (peanut), ''Cicer'' (chickpea), ''Glycine'' (soybean), ''Medicago'' (alfalfa), ''Phaseolus'' (common bean), ''Trifolium'' (clover), ''Vicia'' (vetch), and ''Vigna'' (mung bean). Description This clade circumscribes six subordinate clades: one traditional tribe (Exostyleae) and five informal clades (the genistoids, the vataireoids, the dalbergioids, the ''Andira'' clade, and the Old World Clade), as well as the genus ''Amphimas''. The clade has the following ICPN-compliant, node-based definition: The most inclusive crown clade exhibiting the structural rearrangement in the plastid genome (inversion of a ~50 Kb segment in the large-single copy region with endpoints between the ''accD'' and ''t ...

Dermatophyllum Secundiflorum
''Dermatophyllum secundiflorum'' is a species of flowering shrub or small tree in the family Fabaceae that is native to the Southwestern United States (Texas, New Mexico) and Mexico ( Chihuahua and Coahuila south to Hidalgo, Puebla, and Querétaro). Its common names include Texas mountain laurel, Texas mescalbean, ''frijolito'', and ''frijolillo''. Name Although "mescalbean" is among the plant's common appellations, it bears no relation to the ''Agave'' species used to make the spirit mezcal, nor to the peyote cactus (''Lophophora williamsii''), which contains the hallucinogenic alkaloid mescaline. Description An evergreen, its leaves are pinnately compound, with small, roughly spatulate leaflets; the leaflets are rather thick, and waxy to the touch. Never tall, and rarely having a straight trunk, its bark is smooth in all but the oldest specimens. It grows slowly to a height of and a crown diameter of . Extremely fragrant purple flowers, resembling the smell of grape soda, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cladrastis Kentukea
''Cladrastis kentukea'', the Kentucky yellowwood or American yellowwood (syn. ''C. lutea'', ''C. tinctoria''), is a species of ''Cladrastis'' native to the Southeastern United States, with a restricted range from western North Carolina west to eastern Oklahoma, and from southern Missouri and Indiana south to central Alabama. The tree is sometimes also called Virgilia. Description ''Cladrastis kentukea'' is a small to medium-sized deciduous tree typically growing tall, exceptionally to tall, with a broad, rounded crown and smooth gray bark. The leaves are compound pinnate, 20–30 cm long, with 5-11 (mostly 7-9) alternately arranged leaflets; each leaflet broad ovate with an acute apex; 6–13 cm long and 3–7 cm broad, with an entire margin and a thinly to densely hairy underside. In the fall, the leaves turn a mix of yellow, gold, and orange. The flowers are fragrant, white, produced in ''Wisteria''-like racemes 15–30 cm long. Flowering is in early ...

Crown Clade
In phylogenetics, the crown group or crown assemblage is a collection of species composed of the living representatives of the collection, the most recent common ancestor of the collection, and all descendants of the most recent common ancestor. It is thus a way of defining a clade, a group consisting of a species and all its extant or extinct descendants. For example, Neornithes (birds) can be defined as a crown group, which includes the most recent common ancestor of all modern birds, and all of its extant or extinct descendants. The concept was developed by Willi Hennig, the formulator of phylogenetic systematics, as a way of classifying living organisms relative to their extinct relatives in his "Die Stammesgeschichte der Insekten", and the "crown" and "stem" group terminology was coined by R. P. S. Jefferies in 1979. Though formulated in the 1970s, the term was not commonly used until its reintroduction in 2000 by Graham Budd and Sören Jensen. Contents of the crown gro ...

PhyloCode
The ''International Code of Phylogenetic Nomenclature'', known as the ''PhyloCode'' for short, is a formal set of rules governing phylogenetic nomenclature. Its current version is specifically designed to regulate the naming of clades, leaving the governance of species names up to the rank-based nomenclature codes ('' ICN'', ''ICNCP'', '' ICNP'', '' ICZN'', '' ICVCN''). The ''PhyloCode'' is associated with the International Society for Phylogenetic Nomenclature (ISPN). The companion volume, ''Phylonyms'', establishes 300 taxon names under ''PhyloCode'', serving as examples for those unfamiliar with the code. RegNum is an associated online database for registered clade names. The ''PhyloCode'' regulates phylogenetic nomenclature by providing rules for deciding which associations of names and definitions are considered established, which of those will be considered homonyms or synonyms, and which one of a set of synonyms or homonyms will be considered accepted (generally the one regi ...

ICBN
The ''International Code of Nomenclature for algae, fungi, and plants'' (ICN) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all those "traditionally treated as algae, fungi, or plants".. It was formerly called the ''International Code of Botanical Nomenclature'' (ICBN); the name was changed at the International Botanical Congress in Melbourne in July 2011 as part of the ''Melbourne Code''. which replaced the ''Vienna Code'' of 2005. The current version of the code is the ''Shenzhen Code'' adopted by the International Botanical Congress held in Shenzhen, China, in July 2017. As with previous codes, it took effect as soon as it was ratified by the congress (on 29 July 2017), but the documentation of the code in its final form was not published until 26 June 2018. The name of the ''Code'' is partly capitalized and partly not. The lower-case for "algae, fungi, and plants" indica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxonomic Rank
In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family (biology), family, order (biology), order, class (biology), class, phylum (biology), phylum, kingdom (biology), kingdom, domain (biology), domain. While older approaches to taxonomic classification were phenomenological, forming groups on the basis of similarities in appearance, organic structure and behaviour, methods based on genetic analysis have opened the road to cladistics. A given rank subsumes under it less general categories, that is, more specific descriptions of life forms. Above it, each rank is classified within more general categories of organisms and groups of organisms related to each other through inheritance of phenotypic trait, traits or features from common ancestors. The rank of any ''species'' and the description of its ''genus'' is ''basic''; which means that to iden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eocene
The Eocene ( ) Epoch is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope Carbon-13, 13C in the atmosphere was exceptionally low in comparison with the more common isotope Carbon-12, 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Popigai impact structure, Siberia and in what is now ...
