Amaranthoideae
The Amaranthoideae are a subfamily of the Amaranthaceae. The stamens have anthers with two lobes (locules) and four pollen sacs. The main distribution of the subfamily is in tropical America, in tropical and Southern Africa, and in Australia. The genera ''Amaranthus'' (the amaranths) and ''Celosia'' (the cockscombs) contain many ornamental species, as well as species whose seeds are used as pseudocereals and leaves as leaf vegetables. Systematics The subfamily Amaranthoideae comprises about 57 genera with about 330 species. Phylogenetical research revealed that the subfamily is polyphyletic and its traditional classification (tribe Amarantheae Rchb. with two subtribes Amaranthinae und Aervinae) does not reflect the phylogenetic relationship. Therefore, a new taxonomical grouping is required. Müller & Borsch (2005) recognized several clades: *basal group: ** '' Bosea'' L., on Macaronesian Islands, and in Cyprus and western Himalaya. ** ''Charpentiera'' Gaudich., endemic ...

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] |
Amaranthus Tricolor
''Amaranthus tricolor'', known as edible amaranth, is a species of flowering plant in the genus ''Amaranthus'', part of the family Amaranthaceae. The plant is often cultivated for ornamental and culinary purposes. It is known as bireum in Korea; tampala, tandaljo, or tandalja bhaji in India; callaloo in the Caribbean; and Joseph's coat in other areas, after the biblical figure Joseph, who is said to have worn a coat of many colors. Although it is native to South and South-East Asia, ''A. tricolor'' is one of several species of amaranth cultivated in warm regions across the world. Cultivars have striking yellow, red, and green foliage. ''Amaranthus gangeticus'' ''Amaranthus gangeticus'' is considered a synonym of ''A. tricolor'', but has been recognized as a separate species in the past. ''A. gangeticus'' is also known as elephant-head amaranth. It is an annual flowering plant with deep purple flowers. It can grow to tall. In Bangladesh, it has been used as a leafy vegetable. ...

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 ...

Ptilotus
''Ptilotus'' R.Br. is a genus of approximately 120 species of annual and perennial herbs and shrubs in the family Amaranthaceae. All species are native to mainland Australia, although one species, '' Ptilotus spathulatus'' (R.Br.) Poir., also occurs in Tasmania and another, '' Ptilotus conicus'' R.Br., in Malesia on the islands of Flores and Timor. Most of the diversity is in Western Australia, particularly in the Pilbara. Common names for species in this genus include mulla mulla, foxtails, pussy tails and lamb's tails. The genus was first formally described by botanist Robert Brown in ''Prodromus Florae Novae Hollandiae'' in 1810. In family-level phylogenetic studies, ''Ptilotus'' has been placed within a clade informally known as the 'aervoids'. It has been resolved as monophyletic and is closely related to '' Aerva'' Forssk. An interactive key to the species of ''Ptilotus'' is available at KeyBase. Species Conservation status A number of ''Ptilotus'' species are listed ...

Nothosaerva
''Nothosaerva'' is a monotypic genus of flowering plants in the family Amaranthaceae containing the single species ''Nothosaerva brachiata''. It is native to India, Sri Lanka, Southeast Asia, and eastern Africa Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area .... This species was first described in 1852 with the name ''Pseudanthus''. This turned out to be an illegitimate homonym, so it was renamed ''Nothosaerva'' in 1853.

Monophyletic
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 tak ...
