Haussknechtia
''Haussknechtia'' is a monotypic genus of flowering plants belonging to the family Apiaceae. It only contains one species, ''Haussknechtia elymaitica''. It is commonly known as ''johour'' or white celery in Iran. It is a perennial plant, that is 2-3 m tall glabrous (smooth) and with large bipinnatisect (deeply dissected segments) basal leaves and numerous flowers that are grouped in globose (rounded) umbels, situated on the usually simple or slightly branched stems. It is native to Iran. The genus name of ''Haussknechtia'' is in honour of Heinrich Carl Haussknecht (1838–1903), a German pharmacist and botanical collector. The Latin specific epithet In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, bot ... of ''elymaitica'' refers to Elymais, an ancient region, in 2nd century BC to th ...

Heinrich Carl Haussknecht
Heinrich Carl Haussknecht (30 November 1838 – 7 July 1903) was a German pharmacist and botanical collector who was a native of Bennungen, Sachsen-Anhalt. Trained as a pharmacist, Haussknecht is remembered for collecting and describing numerous species of plants. His botanical explorations took place in Thuringia, Lower Saxony, Greece and the Middle East (the present-day nations of Turkey, Syria, Iraq, Iran), where he discovered, among others ''Tulipa aleppensis''. He established a large herbarium in Weimar, which after his death was placed under the supervision of Joseph Friedrich Nicolaus Bornmüller (1862–1948). In 1949, the "Herbarium Haussknecht" was transferred to the University of Jena. Haussknecht specialized in the study of the genus '' Epilobium'' from the botanical family Onagraceae. In 1884 he published a monograph on the genus called ''Monographie der Gattung Epilobium''. The botanical genus ''Haussknechtia ''Haussknechtia'' is a monotypic genus of flo ...

Apioideae
This is a list of genera belonging to the family Apiaceae. It contains all the genera accepted by Plants of the World Online (PoWO) . A few extra genus names are included that PoWO regards as synonyms. Unless otherwise indicated, the placement of genera into sub-taxa is based on the taxonomy used by the Germplasm Resources Information Network (GRIN). "Not assigned" means either that the genus is unplaced in GRIN or that it is not listed by GRIN. Not assigned to a subfamily In a 2021 molecular phylogenetic study, the ''Platysace'' clade and the genera ''Klotzschia'' and ''Hermas'' fell outside the four subfamilies. It has been suggested that they could be placed in subfamilies of their own. *'' Hermas'' L. *'' Klotzschia'' Cham. *'' Platysace'' Bunge ;Others Subfamily Apioideae Subfamily Azorelloideae Subfamily Mackinlayoideae Subfamily Saniculoideae The NCBI Taxonomy Browser lists the tribes Saniculeae and Steganotaenieae in a separate subfamily, Sanicul ...

Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.' ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. They include all forbs (flowering plants without a woody stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. The term "angiosperm" is derived from the Greek words ἀγγεῖον / ('container, vessel') and σπέρμα / ('seed'), meaning that the seeds are enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Angiosperms are distinguished from the other seed-producing plants, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the common ance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apiaceae
Apiaceae or Umbelliferae is a family of mostly aromatic flowering plants named after the type genus '' Apium'' and commonly known as the celery, carrot or parsley family, or simply as umbellifers. It is the 16th-largest family of flowering plants, with more than 3,700 species in 434 generaStevens, P.F. (2001 onwards)Angiosperm Phylogeny Website Version 9, June 2008. including such well-known and economically important plants as ajwain, angelica, anise, asafoetida, caraway, carrot, celery, chervil, coriander, cumin, dill, fennel, lovage, cow parsley, parsley, parsnip and sea holly, as well as silphium, a plant whose identity is unclear and which may be extinct. The family Apiaceae includes a significant number of phototoxic species, such as giant hogweed, and a smaller number of highly poisonous species, such as poison hemlock, water hemlock, spotted cowbane, fool's parsley, and various species of water dropwort.

Perennial
A perennial plant or simply perennial is a plant that lives more than two years. The term ('' per-'' + '' -ennial'', "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically perennials. Perennialsespecially small flowering plantsthat grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a perennial in its native habitat, or in a milder garden, may be treated by a gardener as an annual and planted out every year, from seed, from cuttings, or from divisions. Tomato vines, for example, live several ye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Umbels
In botany, an umbel is an inflorescence that consists of a number of short flower stalks (called pedicels) that spread from a common point, somewhat like umbrella ribs. The word was coined in botanical usage in the 1590s, from Latin ''umbella'' "parasol, sunshade". The arrangement can vary from being flat-topped to almost spherical. Umbels can be simple or compound. The secondary umbels of compound umbels are known as umbellules or umbellets. A small umbel is called an umbellule. The arrangement of the inflorescence in umbels is referred to as umbellate, or occasionally subumbellate (almost umbellate). Umbels are a characteristic of plants such as carrot, parsley, dill, and fennel in the family Apiaceae; ivy, '' Aralia'' and '' Fatsia'' in the family Araliaceae; and onion (''Allium'') in the family Alliaceae. An umbel is a type of indeterminate inflorescence. A compressed cyme, which is a determinate inflorescence, is called umbelliform if it resembles an umbel. Gallery Fi ...

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus '' Homo'' and within this genus to the species '' Homo sapiens''. '' Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elymais
Elymais or Elamais (Ἐλυμαΐς, Hellenic form of the more ancient name, Elam) was an autonomous state of the 2nd century BC to the early 3rd century AD, frequently a vassal under Parthian control. It was located at the head of the Persian Gulf in Susiana (the present-day region of Khuzestan, Iran). Most of the population probably descended from the ancient Elamites, who once had control of that area. General information The Elymaeans were reputed to be skilled archers. In 187 BC, they killed Antiochus III the Great after he had pillaged their temple of Bel. Nothing is known of their language, even though Elamite was still used by the Achaemenid Empire 250 years before the kingdom of Elymais came into existence. A number of Aramaic inscriptions are found in Elymais. The region's "wealth in silver and gold" is referred to in the deutero-canonical work 1 Maccabees, which refers to Elymais as a "city" of interest to Antiochus IV Epiphanes: the narrative there states t ...

Taxa Named By Pierre Edmond Boissier
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. 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 very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
