Oxybasis
''Oxybasis'' is a flowering plant genus from the subfamily Chenopodioideae of the family Amaranthaceae. It was first described in 1841, and newly used since 2012 for five species that were traditionally grouped into genus ''Chenopodium''. They occur in Europe, Asia, North Africa and America. Description According to Fuentes-Bazan et al. (2012), the species in genus ''Oxybasis'' are non-aromatic annual herbs. Their stems grow erect to ascending or prostrate and are branched with usually alternate, basally sometimes nearly opposite branches. The alternate leaves consist of a petiole and a simple blade. The leaf blade is thickish oder slightly fleshy, and may be triangular, triangular to narrowly triangular, hastate, rhombic, or lanceolate, with entire to dentate margins. The axillary and terminal inflorescences consist of spicately or sometimes paniculately arranged compact glomerules of flowers, ebracteate or in the axils of leaf-like bracts. Usually there a two types of flow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chenopodium
''Chenopodium'' is a genus of numerous species of perennial or annual herbaceous flowering plants known as the goosefoots, which occur almost anywhere in the world. It is placed in the family Amaranthaceae in the APG II system; older classification systems, notably the widely used Cronquist system, separate it and its relatives as Chenopodiaceae, but this leaves the rest of the Amaranthaceae polyphyletic. However, among the Amaranthaceae, the genus ''Chenopodium'' is the namesake member of the subfamily Chenopodioideae. Description The species of ''Chenopodium'' (s.str., description according to Fuentes et al. 2012) are annual or perennial herbs, shrubs or small trees. They generally rely on alkaline soil. They are nonaromatic, but sometimes fetid. The young stems and leaves are often densely covered by vesicular globose hairs, thus looking farinose. Characteristically, these trichomes persist, collapsing later and becoming cup-shaped. The branched stems grow erect, ascen ...

Oxybasis Chenopodioides
''Oxybasis chenopodioides'', (syn. ''Chenopodium chenopodioides'') is a species of flowering plant in the family Amaranthaceae known by the common name low goosefoot. It is native to South America, but it is known in widespread parts of Africa, Asia, Europe, and North America as an introduced species. It grows in wet non-saline and saline soils, such as mudflats, salt marshes, and lake margins. It is an annual herb growing erect to heights approaching 35 to 45 centimeters, or prostrate in a creeping mat. It is green to magenta in color and non-aromatic. The leaves may be several centimeters long and vary in shape from smooth-edged and oval to triangular and lobed or toothed.

Oxybasis Glauca
''Oxybasis glauca'' (syn. ''Chenopodium glaucum''), common name oak-leaved goosefoot, is a species of goosefoot plant native to Europe. It has been introduced and become an invasive weed in North America.

Chenopodioideae
The Chenopodioideae are a subfamily of the flowering plant family Amaranthaceae in the APG III system, which is largely based on molecular phylogeny, but were included - together with other subfamilies - in family Chenopodiaceae in the Cronquist system. Food species comprise Spinach (''Spinacia oleracea''), Good King Henry (''Blitum bonus-henricus''), several ''Chenopodium'' species (Quinoa, Kañiwa, Fat Hen), Orache (''Atriplex spp.''), and Epazote (''Dysphania ambrosioides''). The name is Greek for goosefoot, the common name of a genus of plants having small greenish flowers. Description The Chenopodioideae are annual or perennial herbs, subshrubs, shrub or small trees. The leaves are usually alternate and flat. The flowers are often unisexual. Many species are monoecious or have mixed inflorescences of bisexual and unisexual flowers. Some species are dioecious, like ''Spinacia'', '' Grayia'', ''Exomis'', and '' Atriplex''. In several species of tribe Atripliceae, the fem ...

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] |
Atripliceae
Atripliceae are a tribe of the subfamily Chenopodioideae belonging to the plant family Amaranthaceae. '' Atriplex'' is the largest genus of the tribe. Species of Atripiceae are ecologically important in steppe and semi-desert climates. Distribution Most of the species are distributed in Africa, Australia, and North America, with some others spread out worldwide. Taxonomy Traditional taxonomy Taxonomy is the practice and science of categorization or classification. A taxonomy (or taxonomical classification) is a scheme of classification, especially a hierarchical classification, in which things are organized into groups or types. ... of Atripliceae based on morphological features has been controversial. Molecular studies have found that many genera are not true clades. One such study found that Atripliceae could be divided into two main clades, Archiatriplex, with a few, scattered species, and the larger Atriplex clade, which is highly diverse and found around the wo ...

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 ...

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be Boundaries between the continents of Earth#Asia and Europe, separated from Asia by the drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.
