Coca
Coca is any of the four cultivated plants in the family Erythroxylaceae, native to western South America. Coca is known worldwide for its psychoactive alkaloid, cocaine. Coca leaves contain cocaine which acts as a mild stimulant when chewed or consumed as tea, with slower absorption than purified cocaine and no evidence of addiction or withdrawal symptoms from natural use. The coca plant is a shrub-like bush with curved branches, oval leaves featuring distinct curved lines, small yellowish-white flowers that develop into red berries. Genomic analysis reveals that coca, a culturally and economically important plant, was domesticated two or three separate times from the wild species ''Erythroxylum gracilipes'' by different South American groups during the Holocene. Chewing coca in South America began at least 8,000 years ago, as evidenced by coca leaves and calcite found in house floors in Peru’s Nanchoc Valley, suggesting early communal use alongside the rise of farming. ...

Erythroxylum
''Erythroxylum'' is a genus of tropical flowering plants in the family Erythroxylaceae. Many of the approximately 200 species contain the tropane alkaloid cocaine,Bieri S, Brachet A, Veuthey J, Christen P. Cocaine distribution in wild Erythroxylum species. ''Journal of ethnopharmacology''. 2006; 103: 439-447. and two of the species within this genus, '' Erythroxylum coca'' and '' Erythroxylum novogranatense'', both native to South America, are the main commercial source of cocaine and of the mild stimulant coca tea. Another species, '' Erythroxylum vaccinifolium'' (also known as catuaba) is used as an aphrodisiac in Brazilian drinks and herbal medicine. '' Erythroxylum australe'' was traditionally used by Australian Aborigines for rites and other practices. ''Erythroxylum'' species are food sources for the larvae of some butterflies and moths, including several '' Morpho'' species and '' Dalcera abrasa'', which has been recorded on ''E. deciduum'', and the species of '' Agri ...

Erythroxylum Coca
''Erythroxylum coca'' is one of two species of cultivated coca. Description The coca plant resembles a blackthorn bush, and grows to a height of . The branches are straight, and the leaves, which have a green tint, are thin, opaque, oval, and taper at the extremities. A marked characteristic of the leaf is an areolated portion bounded by two longitudinal curved lines, one line on each side of the midrib, and more conspicuous on the underside of the leaf. Coca plants are mainly found in Colombia. The flowers are small, and disposed in little clusters on short stalks; the corolla is composed of five yellowish-white petals, the anthers are heart-shaped, and the pistil consists of three carpels united to form a three-chambered ovary. The flowers mature into red berries. Unlike ''Erythroxylum novogranatense'', ''Erythroxylum coca'' requires very acidic soil conditions. Soil acidity and water acidity need to be below pH 5.5, with the optimal value being pH 3.5, similar to that of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Sigismund Kunth
Carl Sigismund Kunth (18 June 1788 – 22 March 1850) was a German botanist. He was also known as Karl Sigismund Kunth or anglicized as Charles Sigismund Kunth. He was one of the early systematic botanists who focused on studying the plants of the Americas. Kunth's notable contributions include the publication of ''Nova genera et species plantarum quas in peregrinatione ad plagam aequinoctialem orbis novi collegerunt Bonpland et Humboldt''. This work spanned seven volumes and was published between 1815 and 1825. Early life Kunth was born in Leipzig, Saxony, in modern-day Germany. His uncle, Gottlob Johann Christian Kunth, was a politician and educator who tutored both the explorer Alexander von Humboldt and his older brother, the diplomat Wilhelm von Humboldt, as children. Growing up, Kunth's father didn't have enough money for him to continue studying at the Leipzig Rathsschule. His uncle paid for him to move to Berlin, then a part of Prussia, and take a position at the Pru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta. Angiosperms are by far the most diverse group of Embryophyte, land plants with 64 Order (biology), orders, 416 Family (biology), families, approximately 13,000 known Genus, genera and 300,000 known species. They include all forbs (flowering plants without a woody Plant stem, stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. Angiosperms are distinguished from the other major seed plant clade, 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 commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
