Zygophyllum
''Zygophyllum'' is the type genus of the flowering plant family Zygophyllaceae. The generic name is derived from the Greek language, Greek words ζυγόν (''zygon''), meaning "double", and φυλλον (''phyllon''), meaning "leaf". It refers to the leaves, each of which have two leaflet (botany), leaflets. The genus is distributed in arid and Semi-arid climate, semi-arid regions of Africa, the Mediterranean Basin, central Asia, Australia, and North and South America. Molecular phylogenetics, Molecular phylogenetic analysis suggested that as previously Circumscription (taxonomy), circumscribed, ''Zygophyllum'' was not Monophyly, monophyletic, and the genus was split among a number of other genera, including ''Augea (plant), Augea'', ''Fagonia'', ''Roepera'' and ''Tetraena''. , Plants of the World Online accepted only ''Roepera'' of these genera, regarding ''Augea'', ''Fagonia'' and ''Tetraena'' as synonyms of ''Zygophyllum''.

Fagonia
''Fagonia'' is a genus of wild, flowering plants in the caltrop family, Zygophyllaceae, having about 34 species. The latest reorganization of the genus took place in 2018 when systematists Christenhusz & Byng, Royal Botanical Gardens, Kew (UK) included ''Fagonia spp''.. along with several other Zygophyllum genera, into a new genus named "''Zygophyllum'' L." Species occurring in the US are commonly referred to as fagonbushes. The distribution of the genus includes parts of Africa, the Mediterranean Basin, the Mid-East, India, and parts of North & South America. ''Fagonia'' species have been used ethnobotanically by traditional practitioners under Ayurvedic and other TM healing regimes for many maladies. Species occur in deserts, dry washes, ditches and on rocky outcrops, including at altitude. '' Fagonia laevis'' is a perennial herb of the United States desert southwest. It has opposite leaves, trifoliate with spinescent stipules, a lavender corolla and smooth fruits. Under c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zygophyllaceae
Zygophyllaceae is a family of flowering plants that contains the bean-caper and caltrop. The family includes around 285 species in 22 genera. Plants in the family Zygophyllaceae may be trees, shrubs, or herbs. They are often found in dry habitats. The leaves are usually opposite, often with stipules and spines. Some are cultivated as ornamental plants, such as species of the '' Guaiacum'', ''Zygophyllum'', '' Tribulus'', and '' Larrea'' genera. King Clone, a creosote bush ''(Larrea tridentata)'' in California, is among the world's oldest living organisms. The distribution of plants in the Zygophyllaceae family can be found worldwide in warm tropics and cool-temperate subtropics with a concentration in hot, arid regions with alkaline soils. Regions with different species from this family include Africa, south Asia, India, Australia and parts of the United States. Genera '' Peganum'' was in Zygophyllaceae before being moved to the newly created family Nitrariaceae. Systema ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zygophyllum Fabago
''Zygophyllum fabago'' is a species of plant known by the common name Syrian bean-caper. It is considered a noxious weed of economic importance in much of the western United States. It is native to Asia and East Europe (Russia and Ukraine) and Southeast Europe (Romania). Growth The Syrian bean-caper grows long, thin stems with few oval-shaped, fleshy, waxy green leaflets each 2 to 3 centimeters in length. The flowers are small, compact bunches of five petals each with prominent stamens. The flowers have a taste and scent similar to caper. It grows in masses of individual plants, forming colonies, especially in dry, gravelly, saline, or disturbed areas where other plant life is rare. Characteristics The plant has invasive potential due to its long taproot which, even if fragmented, can produce a new plant, as well as the hardy wax coating on its leaves that tends to protect it from herbicide Herbicides (, ), also commonly known as weed killers, are substances used to control ...

Augea (plant)
''Augea'' is a possible monotypic genus of flowering plants in the family Zygophyllaceae. Its only species is ''Augea capensis'', native to Namibia and the western Cape Province of South Africa. The genus and species were first described by Carl Peter Thunberg in 1794. The genus is placed in the subfamily Zygophylloideae. , the subfamily's division into genera remains disputed. ''Augea'' is accepted by some sources, but regarded as a synonym of ''Zygophyllum'' by others, including Plants of the World Online Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew.

Leaflet (botany)
A leaflet (occasionally called foliole) in botany is a leaf-like part of a compound leaf. Though it resembles an entire leaf, a leaflet is not borne on a main plant stem or branch, as a leaf is, but rather on a leaf, petiole or a branch of the leaf. Compound leaves are common in many plant families and they differ widely in morphology (biology), morphology. The two main classes of compound leaf morphology are Leaf shape, palmate and pinnate. For example, a ''Cannabis, hemp'' plant has palmate compound leaves, whereas some species of ''Acacia sensu lato, Acacia'' have pinnate leaves. The ultimate free division (or leaflet) of a compound leaf, or a pinnate subdivision of a multipinnate leaf is called a pinnule or pinnula.

Monophyly
In biological cladistics for the classification of organisms, monophyly is the condition of a taxonomic grouping being a clade – that is, a grouping of organisms which meets these criteria: # the grouping contains its own most recent common ancestor (or more precisely an ancestral population), i.e. excludes non-descendants of that common ancestor # the grouping contains all the descendants of that common ancestor, without exception Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic'' grouping meets 1. but not 2., thus consisting of the descendants of a common ancestor, excepting one or more monophyletic subgroups. A ''polyphyletic'' grouping meets neither criterion, and instead serves to characterize convergent relationships of biological features rather than genetic relationships – for example, night-active primates, fruit trees, or aquatic insects. As such, these characteristic features of a polyphyletic grouping are ... [...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. For example, 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 molecu ...

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 phylogenetics, 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 (biology), 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 tre ...

Central Asia
Central Asia is a region of Asia consisting of Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan. The countries as a group are also colloquially referred to as the "-stans" as all have names ending with the Persian language, Persian suffix "-stan" (meaning ) in both respective native languages and most other languages. The region is bounded by the Caspian Sea to the southwest, European Russia to the northwest, China and Mongolia to the east, Afghanistan and Iran to the south, and Siberia to the north. Together, the five Central Asian countries have a total population of around million. In the pre-Islamic and early Islamic eras ( and earlier) Central Asia was inhabited predominantly by Iranian peoples, populated by Eastern Iranian-speaking Bactrians, Sogdians, Khwarezmian language, Chorasmians, and the semi-nomadic Scythians and Dahae. As the result of Turkic migration, Central Asia also became the homeland for the Kazakhs, Kyrgyzs, Volga Tatars, Tatars, Turkmens, ...
