Zygophyllum
''Zygophyllum'' is the type genus of the flowering plant family Zygophyllaceae. The generic name is derived from the Greek words ζυγόν (''zygon''), meaning "double", and φυλλον (''phyllon''), meaning "leaf". It refers to the leaves, each of which have two leaflets. The genus is distributed in arid and semi-arid regions of Africa, the Mediterranean Basin, central Asia and Australia. Molecular phylogenetic analysis suggested that as previously circumscribed, ''Zygophyllum'' was not monophyletic, and the genus was split among a number of other genera, including '' Augea'', ''Fagonia'', ''Roepera'' and '' Tetraena''. Species In accordance with International Plant Names Index, genus ''Zygophyllum'' currently has 117 accepted species: *''Zygophyllum acerosum'' (Boiss.)

Augea (plant)
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. i L. Watson and M.J. Dallwitz (1992 onwards).

Zygophyllum Fabago
''Zygophyllum fabago'' is a species of plant known by the common name Syrian bean-caper. It is considered a Noxious weeds, 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 herbicides. Chemical constituents It contains about 0.002% harmine (entire plant). ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 2021 when systematists Christenhusz & Byng 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 the Americas. ''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 cultivation, ''F. indica'' has been found to h ...

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 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 ...

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 ...

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.
