Gelsemiaceae
Gelsemiaceae is a family of flowering plants, belonging to the order Gentianales. The family contains only three genera: ''Gelsemium'', ''Mostuea'' and ''Pteleocarpa''. ''Gelsemium'' has three species, one native to Southeast Asia and southern China and two native to Central America, Mexico, and the southeastern United States. The eight species of ''Mostuea'' are native to tropical areas of South America, Africa, and Madagascar. The two genera were formerly classified in the family Loganiaceae.Peter F. Stevens (2001 onwards). "Gelsemiaceae" At: Angiosperm Phylogeny Website. At: Botanical Databases At: Missouri Botanical Garden Website. (see ''External links'' below) ''Pteleocarpa'' was originally placed in Boraginaceae or in its own family Pteleocarpaceae, but it is most closely related to Gelsemiaceae with which it shares significant characters. The family Gelsemiaceae was described in 1994.Lena Struwe, Victor A. Albert, and Birgitta Bremer. 1994. "Cladistics and family level ...

Pteleocarpa
''Pteleocarpa'' is a genus of flowering plants. The only member of the genus is the western Malesian tree ''Pteleocarpa lamponga''.David J. Mabberley. 2008. ''Mabberley's Plant-Book; a portable dictionary of plants, their classification and uses'' 3rd edition (2008). Cambridge University Press: UK. . (See ''External links'' below). It has had a varied systematic history and has been placed in the families Icacinaceae, Cardiopteridaceae, Boraginaceae, and others.Kanokorn Rueangsawang and Pranom Chantaranothai. 2014. "Studies on Thai Pteleocarpaceae". ''Tropical Natural History'' 14(1):1-6. (See ''External links'' below). It has long been regarded as enigmatic. For example, its winged fruit is quite odd within the family Boraginaceae, where it was usually placed in the 2000s. The family name Pteleocarpaceae had been used, but was not validly published until 2011, when the required description was published in Kew Bulletin.Richard K. Brummitt. 2011.

Gentianales
Gentianales is an order of flowering plants, included within the asterid clade of eudicots. It comprises more than 20,000 species in about 1,200 genera in 5 families. More than 80% of the species in this order belong to the family Rubiaceae. Many of these flowering plants are used in traditional medicine. They have been used to treat pain, anxiety, cancers and neurological conditions. Taxonomy In the classification system of Dahlgren the Gentiales were in the superorder Gentianiflorae (also called Gentiananae). The following families are included according to the APG III system: * Family Apocynaceae (424 genera) * Family Gelsemiaceae (2 genera) * Family Gentianaceae (87 genera) * Family Loganiaceae (13 genera) * Family Rubiaceae (611 genera) Phylogeny The following phylogenetic tree is based on molecular phylogenetic studies of DNA sequences. Etymology It takes its name from the family Gentianaceae, which in turn is based on the name of the type genus, ''Gentiana''. The gen ...

Mostuea
''Mostuea'' is one of only three genera of flowering plants belonging to the small family Gelsemiaceae (the other two being ''Gelsemium'' and '' Pteleocarpa''). ''Mostuea'' and ''Gelsemium'' were formerly placed in the family Loganiaceae, while ''Pteleocarpa'' was placed variously in the families Icacinaceae, Cardiopteridaceae, Boraginaceae, and others, before the description of the Gelsemiaceae was altered formally to accommodate it in 2014.Peter F. Stevens (2001 onwards). "Gelsemiaceae" At: Angiosperm Phylogeny Website. At: Botanical Databases At: Missouri Botanical Garden Website.Nancy F. Refulio-Rodriguez and Richard G. Olmstead. 2014. "Phylogeny of Lamiidae". ''American Journal of Botany'' 101(2):287-299. . ''Mostuea'' is native to Africa and South America. Anecdotal evidence suggests that the roots of certain ''Mostuea'' species are used as ritual aphrodisiacs and entheogens in West Tropical Africa.De Smet, P.A.G.M.

Loganiaceae
The Loganiaceae are a family of flowering plants classified in order Gentianales. The family includes up to 13 genera, distributed around the world's tropics. There are not any great morphological characteristics to distinguish these taxa from others in the order Gentianales. Many members of the Loganiaceae are extremely poisonous, causing death by convulsion. Poisonous properties are largely due to alkaloids such as those found in ''Strychnos''. Glycosides are also present as loganin in ''Strychnos''.Flowering Plants of the World by consultant editor Vernon H. Heywood, 1978, Oxford University Press, Walton Street, Oxford OX2 6DP, England, Earlier treatments of the family have included up to 29 genera. Phylogenetic studies have demonstrated that this broadly defined Loganiaceae was a polyphyletic assemblage, and numerous genera have been removed from Loganiaceae to other families (sometimes in other orders), e.g., Gentianaceae, Gelsemiaceae, Plocospermataceae, Tetrachondrac ...

Gelsemium
''Gelsemium'' is an Asian and North American genus of flowering plants belonging to family Gelsemiaceae. The genus contains three species of shrubs to straggling or twining climbers. Two species are native to North America, and one to China and Southeast Asia. includes description, drawings, distribution map, etc. Carl Linnaeus first classified ''G. sempervirens'' as ''Bignonia sempervirens'' in 1753; Antoine Laurent de Jussieu created a new genus for this species in 1789. ''Gelsemium'' is a Latinized form of the Italian word for jasmine, ''gelsomino''. ''G. elegans'' has the common name ''"heartbreak grass"''. Properties All three species of this genus are poisonous. Active components The active components of gelsemium are the alkaloids, which are present in a concentration of about 0.5%. These consist primarily of gelsemine (a highly toxic compound related to strychnine), with lesser amounts of related compounds (gelsemicine, gelsedine, etc). Other compounds found in the ...

Diagnosis (taxonomy)
In biology, taxonomy () is the science, scientific study of naming, defining (Circumscription (taxonomy), circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxon, taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain (biology), domain, kingdom (biology), kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class (biology), class, order (biology), order, family (biology), family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biologica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Latex
Latex is an emulsion (stable dispersion) of polymer microparticles in water. Latexes are found in nature, but synthetic latexes are common as well. In nature, latex is found as a milky fluid found in 10% of all flowering plants (angiosperms). It is a complex emulsion that coagulates on exposure to air, consisting of proteins, alkaloids, starches, sugars, oils, tannins, resins, and gums. It is usually exuded after tissue injury. In most plants, latex is white, but some have yellow, orange, or scarlet latex. Since the 17th century, latex has been used as a term for the fluid substance in plants, deriving from the Latin word for "liquid". It serves mainly as defense against herbivorous insects. Latex is not to be confused with plant sap; it is a distinct substance, separately produced, and with different functions. The word latex is also used to refer to natural latex rubber, particularly non-vulcanized rubber. Such is the case in products like latex gloves, latex condoms ...

Stipule
In botany, a stipule is an outgrowth typically borne on both sides (sometimes on just one side) of the base of a leafstalk (the petiole). Stipules are considered part of the anatomy of the leaf of a typical flowering plant, although in many species they may be inconspicuous —or sometimes entirely absent, and the leaf is then termed ''exstipulate''. (In some older botanical writing, the term "stipule" was used more generally to refer to any small leaves or leaf-parts, notably prophylls.) The word ''stipule'' was coined by Linnaeus''Concise English Dictionary'' Wordsworth Editions Ltd. 1994, from Latin ''stipula'', straw, stalk. Types of stipules General characteristics The position of stipules on a plant varies widely from species to species, though they are often located near the base of a leaf. Stipules are most common on dicotyledons, where they appear in pairs alongside each leaf. Some monocotyledon plants display stipule-like structures, but only display one per leaf ...
