Pancratioidinae
Amarylloidinae is a now obsolete informal name for an "infrafamily" within the Amaryllidaceae (Amaryllis) family, erected by Hamilton Traub. This grouping was designed to fill a perceived gap between the formal rank of subfamily and tribes. In his treatment of this family, he divided it first into four subfamilies. Within subfamily Amarylloideae he then divided his sixteen tribes into two infrafamilies, Amarylloidinae (12 tribes) and Pancratioidinae (4 tribes), both of which were subsequently demonstrated to be polyphyletic, and hence were abandoned by Dahlgren, who used no rank between family and tribe. On the other hand, he also used a much more restricted Amaryllidaceae corresponding to Traub's subfamily Amarylloideae. Thus Traub's Amarylloideae most closely resembles subfamily Amaryllidoideae ''sensu'' APGIII. Of these infrafamilies, the smaller Pancratioidinae represents the Andean clade of Amaryllidoideae ''sensu'' APGIII, together with the Pancratieae from the Eurasian ...

Amaryllidoideae
Amaryllidoideae (Amaryllidaceae ''s.s.'', amaryllids) is a subfamily of monocot flowering plants in the family Amaryllidaceae, order Asparagales. The most recent APG classification, APG III, takes a broad view of the Amaryllidaceae, which then has three subfamilies, one of which is Amaryllidoideae (the old family Amaryllidaceae), and the others are Allioideae (the old family Alliaceae) and Agapanthoideae (the old family Agapanthaceae). The subfamily consists of about seventy genera, with over eight hundred species, and a worldwide distribution. Description The Amaryllidoideae are herbaceous, perennial flowering plants, usually with bulbs (some are rhizomatous). Their fleshy leaves are arranged in two vertical columns, and their flowers are large. Most of them are bulbous geophytes and many have a long history of cultivation as ornamental plants. They are distinguished from the other two Amaryllidaceae subfamilies (Agapanthoideae and Allioideae) by their unique alkaloidal ...

Amaryllidaceae
The Amaryllidaceae are a family of herbaceous, mainly perennial and bulbous (rarely rhizomatous) flowering plants in the monocot order Asparagales. The family takes its name from the genus ''Amaryllis'' and is commonly known as the amaryllis family. The leaves are usually linear, and the flowers are usually bisexual and symmetrical, arranged in umbels on the stem. The petals and sepals are undifferentiated as tepals, which may be fused at the base into a floral tube. Some also display a corona. Allyl sulfide compounds produce the characteristic odour of the onion subfamily (Allioideae). The family, which was originally created in 1805, now contains about 1600 species, divided into about 70–75 genera, 17 tribes and three subfamilies, the Agapanthoideae (agapanthus), Allioideae (onions and chives) and Amaryllidoideae (amaryllis, daffodils, snowdrops). Over time, it has seen much reorganisation and at various times was combined with the related Liliaceae. Since 2009, a very broa ...

Hamilton Traub
Hamilton Paul Traub (June 18, 1890 – July 14, 1983) was an American botanist. He specialized in the study of Amaryllidaceae. He also did horticultural studies on beans. dr Traub was one of the founding members of the American Amaryllis Society (now the International Bulb Society) in 1933, and for a long time the editor of its annual publication, variously called ''Year Book, American Amaryllis Society'', ''Herbertia'' and ''Plant Life.

Taxonomic Rank
In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family (biology), family, order (biology), order, class (biology), class, phylum (biology), phylum, kingdom (biology), kingdom, domain (biology), domain. While older approaches to taxonomic classification were phenomenological, forming groups on the basis of similarities in appearance, organic structure and behaviour, methods based on genetic analysis have opened the road to cladistics. A given rank subsumes under it less general categories, that is, more specific descriptions of life forms. Above it, each rank is classified within more general categories of organisms and groups of organisms related to each other through inheritance of phenotypic trait, traits or features from common ancestors. The rank of any ''species'' and the description of its ''genus'' is ''basic''; which means that to iden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subfamily
In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end subfamily botanical names with "-oideae", and zoological names with "-inae". See also * International Code of Nomenclature for algae, fungi, and plants * International Code of Zoological Nomenclature * Rank (botany) * Rank (zoology) In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy.

Tribe (biology)
In biology, a tribe is a taxonomic rank above genus, but below family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxonomic ranks from genus upwards are capitalized, including both tribe and subtribe. In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology, the form of tribe names is as in botany, e.g., Pseudomonadeae, based on the ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Rolf Dahlgren
Rolf Martin Theodor Dahlgren (7 July 1932 – 14 February 1987) was a Swedish-Danish botanist and professor at the University of Copenhagen from 1973 to his death. Life Dahlgren was born in Örebro on 7 July 1932 to apothecary Rudolf Dahlgren and wife Greta née Dahlstrand. He took his MSc degree in Biology in (1955) and PhD degree in Botany in (1963) at Lund University. He was killed in a car crash in Scania, Sweden on 14 February 1987. Career He continued working on South African plants during expeditions in 1956-57 and 1965–66, while affiliated with the ''Botanical Museum'' in Lund as ''docent''. In 1973, he became professor of botany at the University of Copenhagen. Here, he developed his system of Angiosperm classification, based on many more characters simultaneously than previous systems, most notably many chemical plant traits (see also chemotaxonomy). Although the system was first presented in Danish, it rapidly gained widespread acceptance, particularly due to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sensu
''Sensu'' is a Latin word meaning "in the sense of". It is used in a number of fields including biology, geology, linguistics, semiotics, and law. Commonly it refers to how strictly or loosely an expression is used in describing any particular concept, but it also appears in expressions that indicate the convention or context of the usage. Common qualifiers ''Sensu'' is the ablative case of the noun ''sensus'', here meaning "sense". It is often accompanied by an adjective (in the same case). Three such phrases are: *''sensu stricto'' – "in the strict sense", abbreviation ''s.s.'' or ''s.str.''; *''sensu lato'' – "in the broad sense", abbreviation ''s.l.''; *''sensu amplo'' – "in a relaxed, generous (or 'ample') sense", a similar meaning to ''sensu lato''. Søren Kierkegaard uses the phrase ''sensu eminenti'' to mean "in the pre-eminent r most important or significantsense". When appropriate, comparative and superlative adjectives may also be used to convey the meaning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
APGIII
The APG III system of flowering plant classification is the third version of a modern, mostly molecular-based, system of plant taxonomy being developed by the Angiosperm Phylogeny Group (APG). Published in 2009, it was superseded in 2016 by a further revision, the APG IV system. Along with the publication outlining the new system, there were two accompanying publications in the same issue of the Botanical Journal of the Linnean Society: * The first, by Chase & Reveal, was a formal phylogenetic classification of all land plants (embryophytes), compatible with the APG III classification. As the APG have chosen to eschew ranks above order, this paper was meant to fit the system into the existing Linnaean hierarchy for those that prefer such a classification. The result was that all land plants were placed in the class Equisetopsida, which was then divided into 16 subclasses and a multitude of superorders. * The second, by Haston ''et al.'', was a linear sequence of families follow ...

Andean
The Andes, Andes Mountains or Andean Mountains (; ) are the List of mountain ranges#Mountain ranges by length, longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is long, wide (widest between 18th parallel south, 18°S – 20th parallel south, 20°S latitude), and has an average height of about . The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. Along their length, the Andes are split into several ranges, separated by intermediate depression (geology), depressions. The Andes are the location of several high plateaus—some of which host major cities such as Quito, Bogotá, Cali, Arequipa, Medellín, Bucaramanga, Sucre, Mérida, Mérida, Mérida, El Alto and La Paz. The Altiplano, Altiplano plateau is the world's second-highest after the Tibetan plateau. These ranges are in turn grouped into three major di ...
