Camphorosmeae
Camphorosmeae is a species-rich tribe of the Amaranthaceae, formerly Chenopodiaceae, with 20 genera and about 179 species. It is classified as a single tribe of subfamily Camphorosmoideae. Description The Camphorosmeae are mostly dwarf shrubs or annuals (rarely perennial herbs) with spreading or ascending branches. The plants are more or less densely covered with appressed or spreading hairs. The alternate leaves are often succulent, only a few annual species have thin and flat leaves. The inconspicuous flowers sit solitary or in axillary clusters of 2–3 (5) in the axil of a subtending bract. They differ from the related subfamily Salsoloideae by the absence of bracteoles. The flowers are mostly bisexual. The perianth consists of (3–) 5 membranous or scarious tepals, which are often fused for about 1/5 to 4/5 of their length. 4–5 stamens are basally fused in a hypogynous disc. They have mostly exserted anthers without appendages. The pollen grains differ from Salsoloidea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Salsoloideae
The Salsoloideae are a subfamily of the Amaranthaceae, formerly in family Chenopodiaceae. Description These are herbs, subshrubs, shrubs and some trees. Stems and leaves are often succulent. The ovary contains a spiral embryo. In most genera, scarious wings develop at the outside of the fruiting perianth, allowing for dispersal by the wind (anemochory). In tribe Caroxyleae, the stamens have vesiculose anther appendages, discolor with anthers, that probably play a role for insect pollination. In tribe Salsoleae the anther appendages are absent or small and inconspicuous. Distribution The area with most species (center of diversity) are the deserts and semideserts of Central-Asia and the Middle East. Distribution of the subfamily extends to the Mediterranean, to Middle-Europe, north and south Africa, and Australia, some species have also been introduced to America. Many species grow in dry habitats (xerophytes) or tolerate salty soils (halophytes), some are ruderals. Photos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amaranthaceae
Amaranthaceae is a family of flowering plants commonly known as the amaranth family, in reference to its type genus ''Amaranthus''. It includes the former goosefoot family Chenopodiaceae and contains about 165 genera and 2,040 species, making it the most species-rich lineage within its parent order, Caryophyllales. Description Vegetative characters Most species in the Amaranthaceae are annual or perennial herbs or subshrubs; others are shrubs; very few species are vines or trees. Some species are succulent. Many species have stems with thickened nodes. The wood of the perennial stem has a typical "anomalous" secondary growth; only in subfamily Polycnemoideae is secondary growth normal. The leaves are simple and mostly alternate, sometimes opposite. They never possess stipules. They are flat or terete, and their shape is extremely variable, with entire or toothed margins. In some species, the leaves are reduced to minute scales. In most cases, neither basal nor terminal aggrega ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Their leaves are variable. The flowers are normally inconspicuous, in spike-like inflorescences without bracteoles. The fruits are s. The seed contains an annular, horseshoe-shaped or folded embryo that surrounds the perisperm. The fruiting perianth remains either unappendaged or develops 5 wings.

Ruderal
A ruderal species is a plant species that is first to colonize disturbed lands. The disturbance may be natural for example, wildfires or avalanchesor the consequences of human activities, such as construction ( of roads, of buildings, mining, etc.) or agriculture (abandoned fields, irrigation, etc.). The term ''ruderal'' originates from the Latin word ''rudus'', meaning "rubble". Ruderal species typically dominate the disturbed area for a few years, gradually losing the competition to other native species. However, in extreme disturbance circumstances, such as when the natural topsoil is covered with a foreign substance, a single-species ruderal community may become permanently established. In addition, some ruderal invasive species may have such a competitive advantage over the native species that they, too, may permanently prevent a disturbed area from returning to its original state despite natural topsoil.

Eokochia
''Eokochia'' is a monotypic genus of flowering plants belonging to the family Amaranthaceae. The only species is ''Eokochia saxicola''. Its native range is mainland Italy and Sicily. The genus name is in honour of Wilhelm Daniel Joseph Koch (1771–1849), a German physician and botanist, and the epithet of 'saxicola' is derived from 2 Latin words; ''saxum'' meaning rock and ''incola'' meaning dwelling in. It was first described and published in Taxon In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit.

Polyphyletic
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 systema ...

Phylogenetic
In biology, phylogenetics (; from Greek φυλή/ φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, protein amino acid sequences, or morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An unrooted tree diagram (a network) makes no assumption about the ancestral line, and does ...

Alfred Moquin-Tandon
Christian Horace Benedict Alfred Moquin-Tandon (7 May 1804 – 15 April 1863) was a French naturalist and doctor. Moquin-Tandon was professor of zoology at Marseille from 1829 until 1833, when he was appointed professor of botany and director of the botanical gardens at Toulouse. In 1850, he was sent by the French government to Corsica to study the island's flora. In 1853, he moved to Paris, later becoming director of the Jardin des Plantes and the Académie des Sciences. His books included ''L'Histoire Naturelle des Iles Canaries'' (1835–44), co-authored with Philip Barker Webb and Sabin Berthelot. One of his specialities was the family Amaranthaceae (The Amaranth family). Several genera of plants have been named in his honour, including in 1838, DC. published ''Moquinia'', a genus of flowering plants from Brazil, in the ''Moquinia'' tribe within the sunflower family. Then in 1954, Simone Balle published '' Moquiniella'' a genus of flowering plants from Africa, belonging ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
