Clarkeulia spadix [SEP] taxon rank
Peltandra virginica


on the Red List of Threatened Species 2016, "P. virginica" is a taxon of Least Concern, this is because of its broad range in eastern and central North America. In some areas within the range of "P. virginica" the populations are diminishing. It has also been found in California. While common in most of its range, "P. virginica" is listed as Endangered in Iowa. In the pistillate stage the spadix of "P. virginica" is entirely covered by the spathe, not allowing insects to pollinate

Taxonomic rank


not to say that a taxon at any other rank may not be sharply defined, or that any species is guaranteed to be sharply defined. It varies from case to case. Ideally, a taxon is intended to represent a clade, that is, the phylogeny of the organisms under discussion, but this is not a requirement. A classification in which all taxa have formal ranks cannot adequately reflect knowledge about phylogeny. Since taxon names are dependent on ranks in traditional Linnaean systems of classification, taxa without ranks cannot be

Spadix (botany)


In botany, a spadix ( ; plural spadices , ) is a type of spike inflorescence having small flowers borne on a fleshy stem. Spadices are typical of the family Araceae, the arums or aroids. The spadix is typically surrounded by a leaf-like curved bract known as a spathe. For example, the "flower" of the well known "Anthurium" spp. is a typical spadix with a large colorful spathe. Monoecious aroids have unisexual male and female flowers on the same individual and the spadix is usually organized

Spadix (zoology)


In the field of zoology, a spadix ( ; plural spadices , ) is a secondary sexual organ found in some cephalopods and hydrozoans. In the genus "Nautilus", the spadix is a composite erectile organ in the male located in the oral region which is composed of four highly modified tentacles and which is paired with a somewhat smaller antispadix that is also composed of four tentacles. The spadix is normally a concealed organ but quickly becomes distended upon the animal's death. The exact function of the spadix and antispadix in "

small flowers which are perfect, containing male and female structures. The flowers are contained in dense spirals on the spadix. The spadix is often elongated into a spike shape, but it can be globe-shaped or club-shaped. Beneath the spadix is the spathe, a type of bract. This is variable in shape, as well, but it is lance-shaped in many species. It may extend out flat or in a curve. Sometimes it covers the spadix like a hood. The fruits develop from the

Philodendron bipinnatifidum


. The small, petalless flowers are on a spadix that is enclosed within a spathe. They are usually white or inflorescent. The reproductive organ consists of a spadix grown at the center of a reproductive layer called the spathe. The spathe is sometimes mistaken to be a flower, but it is really a modified leaf that serves to protect the spadix. The spadix is divided into three sections: fertile male flowers at the tip, sterile male flowers at the center, and fertile female flowers toward the end of the flower chamber

Form (botany)


In botanical nomenclature, a form ("forma", plural "formae") is one of the "secondary" taxonomic ranks, below that of variety, which in turn is below that of species; it is an infraspecific taxon. If more than three ranks are listed in describing a taxon, the "classification" is being specified, but only three parts make up the "name" of the taxon: a genus name, a specific epithet, and an infraspecific epithet. The abbreviation "f." or the

Infraspecific name


In botany, an infraspecific name is the scientific name for any taxon below the rank of species, i.e. an infraspecific taxon. (A "taxon", plural "taxa", is a group of organisms to be given a particular name.) The scientific names of botanical taxa are regulated by the "International Code of Nomenclature for algae, fungi, and plants" (ICN). This specifies a 'three part name' for infraspecific taxa, plus a 'connecting term' to indicate the rank of the name

A semi-erect spadix emerges from one side of the flower stem. The spadix is solid, cylindrical, tapers at each end, and is 5 to 10 cm in length. A covering spathe, as is usual with Acoraceae, is absent. The spadix is densely crowded with tiny greenish-yellow flowers. Each flower contains six petals and stamens

Taxon


In biology, a taxon (plural taxa; back-formation from "taxonomy") is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is not uncommon, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given

(Note: a "species group" defined as a taxon, rather than as a category of ranks, has an unofficial rank, one of several such ranks between the subgenus and species levels sometimes used by zoologists in taxa with many species; see Taxonomic rank.)

Plant taxonomy is an empirical science, a science that determines what constitutes a particular taxon (taxonomic grouping, plural: taxa): e.g. "What plants belong to this species?" and "What species belong to this genus?". The definition of the limits of a taxon is called its 'circumscription'. For a particular taxon, if two taxonomists agree exactly on its circumscription, rank and position (i.e. the

For example, a particular species could, over time, have had two or more species-rank names published for it, while the same is applicable at higher ranks such as genera, families, orders, etc. In each case, the earliest published name is called the senior synonym, while the later name is the junior synonym.

Tactusa spadix


Tactusa spadix is a moth of the family Micronoctuidae. It is known from southern Laos, in Southeast Asia. The wingspan of "Tactusa spadix" is about 12 mm. The ground colour of the forewings is brown, with a very large black triangular patch, including the fringes, that extends from the antemedial point on the costa to the apex and to the tornal edge. There is a large, light-brown patch present inside this large patch, located close to the apex. Only the terminal lines are visible as

shorter than the spathe. On the spadix are found fertile female, fertile male, and sterile male flowers. The fertile male and female flowers are separated on the spadix by a sterile zone or staminodal region composed of sterile male flowers. This barrier of sterile male flowers ensures fertile male flowers do not fertilize the female flowers. The arrangement tends to be vertical, with fertile male flowers at the top of the spadix followed by sterile male flowers, and fertile female flowers very close to the bottom in the region known as the

a deep green on the outside and dark burgundy red on the inside, with a deeply furrowed texture. The spadix is hollow and resembles a large baguette. Near the bottom of the spadix, hidden from view inside the sheath of the spathe, the spadix bears two rings of small flowers. The upper ring bears the male flowers, the lower ring is spangled with bright red-orange carpels.

Many small rodents appear to find the spadix particularly attractive; finding examples of the plant with much of the spadix eaten away is common. The spadix produces heat and probably scent as the flowers mature, and this may attract the rodents. "Arum maculatum" is also known as cuckoo pint or cuckoo-pint in the British Isles and is named thus in Nicholas Culpepers' famous 17th-century herbal. This is a name it

Although the family Acoraceae was originally described in 1820, since then "Acorus" has traditionally been included in Araceae in most classification systems, as in the Cronquist system. The family has recently been resurrected as molecular systematic studies have shown that "Acorus" is not closely related to Araceae or any other monocot family,

The sheath was originally classified by Adolf Engler as a spathe due it being the last foliar piece before the spadix. He also noted that species lacked a sympodial leaf. However, in a 1988 paper by Thomas Ray, he argued that the structure was misidentified by Engler and was actually a sympodial leaf. According to Ray the spathe was missing and not the sympodial leaf.

PhyloCode


content of a taxon, other than the type, is not specified by the rank-based codes. In contrast, under phylogenetic nomenclature, the content of taxa are delimited using a definition that is based on phylogeny (i.e., ancestry and descent) and uses specifiers (e.g., species, specimens, apomorphies) to indicate actual organisms. The formula of the definition indicates an ancestor. The defined taxon, then, is that ancestor and all of its descendants. Thus, the content of a phylogenetically defined taxon relies on

given names. Alternative approaches, such as using circumscriptional names, avoid this problem. There are no rules for how many species should make a genus, a family, or any other higher taxon (that is, a taxon in a category above the species level). It should be a natural group (that is, non-artificial, non-polyphyletic), as judged by a biologist, using all the information available to them. Equally ranked higher taxa in different phyla are not necessarily equivalent (e.g., it

Phylogenetic nomenclature


Phylogenetic nomenclature, often called cladistic nomenclature, is a method of nomenclature for taxa in biology that uses phylogenetic definitions for taxon names as explained below. This contrasts with the traditional approach, in which taxon names are defined by a "type", which can be a specimen or a taxon of lower rank, and a description in words. Phylogenetic nomenclature is currently not regulated, but the "International Code of Phylogenetic Nomenclature" ("PhyloCode") is intended to regulate it once it is ratified.

Since taxonomists may disagree as to the circumscription, position or rank of a taxon, there can be more than one correct name for a particular plant. These may also be called synonyms.

This may occur when a taxonomist finds and recognises a taxon and thinks of a name, but delays publishing it in an adequate manner. A common reason for this is that a taxonomist intends to write a "magnum opus" that provides an overview of the group, rather than a series of small papers. Another reason is that the code of nomenclature changes with time, and

A taxon is usually assigned a rank when it is given its formal name. The basic ranks are species and

Anubias pynaertii


a creeping and rooting rhizome that is 0.5-1.5 cm thick. The spathe is 2-3.5 cm long and has a 7–27 cm long peduncle. The spadix is 2.5-3.5 cm long and about as long as the spathe. The upper part is covered with male flowers, of which the 4-6 stamens are fused into synandria, with the thecae covering the side of the synandrium entirely as well as the larger part of the top of the synandrium. The lower part of the spadix is covered with female flowers

, cases of 200 beetles at a time have been observed and almost always the beetles are of the same species. Another feature of this symbiotic relationship, less well understood, is the series of events in which the spadix begins to heat up prior to the spathe opening up for the beetles. This process is known as thermogenesis. By the time the spathe is open and the beetles have arrived, the spadix is usually quite hot; up to around 46 °C in some species, but usually around 35 °C.

Philodendron


The thermogenesis coincides with the arrival of the beetles and appears to increase their presence. The maximum temperature reached by the spadix remains about 20 °C higher than the outside ambient temperature. The time dependence of the temperature can vary from species to species. In some species, the temperature of the spadix will peak on the arrival of the beetles, then decrease, and finally increase reaching a maximum once again when the philodendron is ready for the beetles to leave. Other species, though, only show a maximum temperature on the

the spathe may be to maximize the heat's ability to waft the pheromones into the air. Oxidizing stored carbohydrates and lipids has been found to be the energy source for thermogenesis. The part of the spadix that heats up is the sterile zone. As it heats up, carbohydrates are used, but once the spadix has reached its maximum temperature, lipids are oxidized. The lipids are not first converted to carbohydrates, but rather are directly oxidized. The thermogenic reaction is triggered when concentrations of acetosalicytic acid form in the sterile zone

Taxonomic rank


In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in a taxonomic hierarchy. Examples of taxonomic ranks are species, genus, family, order, class, phylum, kingdom, domain, etc. 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 traits or features from common ancestors. The rank

The "International Code of Zoological Nomenclature" defines "rank" as: "The level, for nomenclatural purposes, of a taxon in a taxonomic hierarchy (e.g. all families are for nomenclatural purposes at the same rank, which lies between superfamily and subfamily)." In his landmark publications, such as the "Systema Naturae", Carl Linnaeus used a ranking scale limited to: kingdom, class, order, genus, species, and one rank below species. Today, nomenclature is regulated

Sorbeoconcha


Sorbeoconcha is a taxonomic clade of snails, i.e. gastropods, mainly marine species with gills and opercula, within the clade Caenogastropoda. The taxon Sorbeoconcha was named by Winston Ponder and David R. Lindberg in 1997. According to the older taxonomy by Ponder and Lindberg the suborders within the order Sorbeoconcha are: In the taxonomy by Bouchet & Rocroi (2005), the clade Sorbeoconcha was declared a taxon of unspecified rank, within the clade Caenogastropoda. It comprises the superfamily Cerithioidea, the superfamily Campaniloidea, the informal group Ptenoglossa and the clade

Stomatellinae is a subfamily of small sea snails with a brilliantly nacreous interior of the shell, marine gastropod mollusks in the family Trochidae, the top snails. In the earlier classification used in the Treatise on Invertebrate Paleontology, the Stomatellidae was included in the Archaeogastropoda, however, this taxon is now largely abandoned in favor of the more recently defined Vetigastropoda. According to Bouchet & Rocroi (2005), Williams et al. (2008) and Williams et al. (2010) this taxon underwent a rank change from family Stomatellidae to

Synonym (taxonomy)


Given that the correct name of a taxon depends on the taxonomic viewpoint used (resulting in a particular circumscription, position and rank) a name that is one taxonomist's synonym may be another taxonomist's correct name (and "vice versa"). Synonyms may arise whenever the same taxon is described and named more than once, independently. They may also arise when existing taxa are changed, as when two taxa are joined to become one, a species is moved to a different genus, a variety is moved to a

flowers become unreceptive to further pollination. Additionally, the spadix moves from its 45° position and presses up flush to the spathe. Towards the end of male anthesis, the spathe begins to close from the bottom, working its way up and forcing the beetles to move up and across the upper region of the spathe, where the fertile male flowers are located. In doing so, the philodendron controls when the beetles come and when they leave and forces them to rub against the top of the spadix where the pollen is located

Spathiphyllum wallisii, commonly known as peace lily, white sails, or spathe flower is a very popular indoor house plant of the family Araceae. The genus name means "spathe-leaf", and the specific epithet is named after Gustav Wallis, the German plant collector. It is a herbaceous perennial which produces flowers in the typical aroid structure: a densely crowded inflorescence called a spadix is subtended by one large bract called a spathe (occasionally two spathes are produced, with the upper spathe smaller). The spadix is generally

In bacteriology, a taxon in disguise is a species, genus or higher unit of biological classification whose evolutionary history reveals has evolved from another unit of similar or lower rank, making the parent unit paraphyletic. This happens when rapid evolution makes a new species appear radically different from the ancestral group, so that it is not (initially) recognised as belonging to the parent phylogenetic group, leaving the latter an evolutionary grade. While the term is from bacteriology, parallel examples are found throughout the tree of life. E.g. four-
