Burseraceae Genera
The Burseraceae are a moderate-sized family of 17-19 genera and about 540 species of woody flowering plants. The actual numbers given in taxonomic sources differ according to taxonomic revision at the time of writing. The Burseraceae are also known as the torchwood family, the frankincense and myrrh family, or simply the incense tree family. The family includes both trees and shrubs; its species are native to tropical regions of Africa, Asia, Australasia, and the Americas. Because of taxonomic revision, as the family size (in terms of genera and species) differs according to the time period of study; so, too, does the family's higher-level relationships, including order. Burseraceae is a genetically-supported monophyletic group since APG III and is frequently cited within the Sapindales. It is recognized as a sister group to the Anacardiaceae. The Burseraceae are characterized by the generally non-allergenic resin they produce in virtually all plant tissue and their distinct ...

Bursera Simaruba
''Bursera simaruba'', commonly known as gumbo-limbo, the tourist tree, copperwood, almácigo, chaca, West Indian birch, naked Indian, and turpentine tree, is a tree species in the family Burseraceae, native to the Neotropics, from South Florida to Mexico and the Caribbean to Brazil, Nicaragua, and Venezuela. ''Bursera simaruba'' is prevalent in the Petenes mangroves ecoregion of the Yucatán, where it is a subdominant plant species to the mangroves. In the United States, specimens may be found in the Gulf of Mexico along the western coast of Florida. Description ''Bursera simaruba'' is a small to medium-sized tree growing to 30 meters tall, with a diameter of one meter or less at 1.5 meters above ground.Foster (2007) The bark is shiny dark red, and the leaves are spirally arranged and pinnate with 7-11 leaflets, each leaflet broad ovate, 4–10 cm long and 2–5 cm broad.

Taxonomic Rank
In biology, taxonomic rank (which some authors prefer to call nomenclatural rank because ranking is part of nomenclature rather than taxonomy proper, according to some definitions of these terms) is the relative or absolute level of a group of organisms (a ''taxon'') in a hierarchy that reflects evolutionary relationships. Thus, the most inclusive clades (such as Eukarya and Animalia) have the highest ranks, whereas the least inclusive ones (such as ''Homo sapiens'' or ''Bufo bufo'') have the lowest ranks. Ranks can be either relative and be denoted by an indented taxonomy in which the level of indentation reflects the rank, or absolute, in which various terms, such as species, genus, Family (biology), family, Order (biology), order, Class (biology), class, Phylum (biology), phylum, Kingdom (biology), kingdom, and Domain (biology), domain designate rank. This page emphasizes absolute ranks and the rank-based codes (the International Code of Zoological Nomenclature, Zoological Code, ...

Eocene
The Eocene ( ) is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (Ma). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''Ēṓs'', 'Eos, Dawn') and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch.See: *Letter from William Whewell to Charles Lyell dated 31 January 1831 in: * From p. 55: "The period next antecedent we shall call Eocene, from ήως, aurora, and χαινος, recens, because the extremely small proportion of living species contained in these strata, indicates what may be considered the first commencement, or ''dawn'', of the existing state of the animate creation." The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isoto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Paleocene
The Paleocene ( ), or Palaeocene, is a geological epoch (geology), epoch that lasted from about 66 to 56 mya (unit), million years ago (mya). It is the first epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name is a combination of the Ancient Greek ''palaiós'' meaning "old" and the Eocene Epoch (which succeeds the Paleocene), translating to "the old part of the Eocene". The epoch is bracketed by two major events in Earth's history. The K–Pg extinction event, brought on by an asteroid impact (Chicxulub impact) and possibly volcanism (Deccan Traps), marked the beginning of the Paleocene and killed off 75% of species, most famously the non-avian dinosaurs. The end of the epoch was marked by the Paleocene–Eocene Thermal Maximum (PETM), which was a major climatic event wherein about 2,500–4,500 gigatons of carbon were released into the atmosphere and ocean systems, causing a spike in global temperatures and ocean acidification. ...

Urushiol-induced Contact Dermatitis
Urushiol-induced contact dermatitis (also called Toxicodendron dermatitis or Rhus dermatitis) is a type of allergic contact dermatitis caused by the oil urushiol found in various plants, most notably sumac family species of the genus ''Toxicodendron'': poison ivy, Toxicodendron diversilobum, poison oak, poison sumac, and the Toxicodendron vernicifluum, Chinese lacquer tree. The name is derived from the Japanese word for the sap of the Chinese lacquer tree, ''urushi''. Other plants in the Anacardiaceae, sumac family (including mango, pistachio, the Burmese lacquer tree, the India marking nut tree, and the cashew) also contain urushiol, as do unrelated plants such as ''Ginkgo biloba.'' As is the case with all contact dermatitis, urushiol-induced allergy, allergic rashes are a Type IV hypersensitivity, Type IV hypersensitivity reaction, also known as delayed-type hypersensitivity. Symptoms include itching, inflammation, oozing, and, in severe cases, a burning sensation. The American ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anacardiaceae
The Anacardiaceae, commonly known as the cashew family or sumac family, are a family of flowering plants, including about 83 genera with about 860 known species. Members of the Anacardiaceae bear fruits that are drupes and in some cases produce urushiol, an irritant. The Anacardiaceae include numerous genera, several of which are economically important, notably cashew (in the type genus '' Anacardium''), mango, Chinese lacquer tree, yellow mombin, Peruvian pepper, poison ivy, poison oak, sumac, smoke tree, marula and cuachalalate. The genus '' Pistacia'' (which includes the pistachio and mastic tree) is now included, but was previously placed in its own family, the Pistaciaceae. The cashew family is more abundant in warm or tropical regions with only a few species living in the temperate zones. Mostly native to tropical Americas, Africa and India. '' Pistacia'' and some species of '' Rhus'' can be found in southern Europe, '' Rhus'' species can be found in much of N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sister Group
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxono ...

Sapindales
Sapindales is an order of flowering plants. Well-known members of Sapindales include citrus; maples, horse-chestnuts, lychees and rambutans; mangos and cashews; frankincense and myrrh; mahogany and neem. The APG III system of 2009 includes it in the clade malvids (in rosids, in eudicots) with the following nine families: * Anacardiaceae * Biebersteiniaceae *Burseraceae * Kirkiaceae * Meliaceae * Nitrariaceae (including Peganaceae and Tetradiclidaceae) *Rutaceae *Sapindaceae * Simaroubaceae The APG II system of 2003 allowed the optional segregation of families now included in the Nitrariaceae. In the classification system of Dahlgren the Rutaceae were placed in the order Rutales, in the superorder Rutiflorae (also called Rutanae). The Cronquist system of 1981 used a somewhat different circumscription, including the following families: *Staphyleaceae * Melianthaceae * Bretschneideraceae * Akaniaceae *Sapindaceae * Hippocastanaceae * Aceraceae *Burseraceae * Anaca ...
