Plowmania
''Plowmania'' is a monotypic genus of flowering plants belonging to the family Solanaceae. The only species is ''Plowmania nyctaginoides''. Fully hardy, fast-growing evergreen climber, stems up to long. It has 4-angled stems, pinnate leaves, up long. From spring to autumn, it produces racemes of tubular orange flowers, up to 2.5cm long. It is native to Mexico and Guatemala. Growing on volcanic peaks at high-elevations. The genus name of ''Plowmania'' is in honour of Timothy Plowman (1944–1989), an American ethnobotanist best known for his intensive work over the course of 15 years on the genus ''Erythroxylum'', and the cultivated coca species in particular. 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 ''nyctaginoides'' means resembling ...

Timothy Plowman
Timothy Charles Plowman (November 17, 1944 – January 7, 1989) was an ethnobotanist best known for his intensive work over the course of 15 years on the genus ''Erythroxylum'' in general, and the cultivated coca species in particular. He collected more than 700 specimens from South America, housed in the collection of the Field Museum of Natural History.http://fm1.fieldmuseum.org/collections/search.cgi?dest=erthroy Plowman joined the Field Museum of Natural History in 1978 where he became tenured in 1983 and was appointed Curator in 1988. He published more than 80 scientific papers (46 on ''Erythroxylum'') and served as editor for several scientific journals. He is one of the main subjects of ''One River: Explorations and Discoveries in the Amazon Rain Forest'' by Wade Davis. Both were students of Richard Evans Schultes, the father of modern ethnobotany. Plowman died of AIDS, which he contracted from pre-trip inoculations. The nightshade species '' Brunfelsia plowma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solanaceae
The Solanaceae , or nightshades, are a family of flowering plants that ranges from annual and perennial herbs to vines, lianas, epiphytes, shrubs, and trees, and includes a number of agricultural crops, medicinal plants, spices, weeds, and ornamentals. Many members of the family contain potent alkaloids, and some are highly toxic, but many—including tomatoes, potatoes, eggplant, bell and chili peppers—are used as food. The family belongs to the order Solanales, in the asterid group and class Magnoliopsida ( dicotyledons). The Solanaceae consists of about 98 genera and some 2,700 species, with a great diversity of habitats, morphology and ecology. The name Solanaceae derives from the genus ''Solanum''. The etymology of the Latin word is unclear. The name may come from a perceived resemblance of certain solanaceous flowers to the sun and its rays. At least one species of ''Solanum'' is known as the "sunberry". Alternatively, the name could originate from the Latin verb ''sol ...

Monotypic Genus
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. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds 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 (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Guatemala
Guatemala ( ; ), officially the Republic of Guatemala ( es, República de Guatemala, links=no), is a country in Central America. It is bordered to the north and west by Mexico; to the northeast by Belize and the Caribbean; to the east by Honduras; to the southeast by El Salvador and to the south by the Pacific Ocean. With an estimated population of around million, Guatemala is the most populous country in Central America and the 11th most populous country in the Americas. It is a representative democracy with its capital and largest city being Nueva Guatemala de la Asunción, also known as Guatemala City, the most populous city in Central America. The territory of modern Guatemala hosted the core of the Maya civilization, which extended across Mesoamerica. In the 16th century, most of this area was conquered by the Spanish and claimed as part of the viceroyalty of New Spain. Guatemala attained independence in 1821 from Spain and Mexico. In 1823, it became part of the Fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethnobotanist
Ethnobotany is the study of a region's plants and their practical uses through the traditional knowledge of a local culture and people. An ethnobotanist thus strives to document the local customs involving the practical uses of local flora for many aspects of life, such as plants as medicines, foods, intoxicants and clothing. Richard Evans Schultes, often referred to as the "father of ethnobotany", explained the discipline in this way: Ethnobotany simply means ... investigating plants used by societies in various parts of the world. Since the time of Schultes, the field of ethnobotany has grown from simply acquiring ethnobotanical knowledge to that of applying it to a modern society, primarily in the form of pharmaceuticals. Intellectual property rights and benefit-sharing arrangements are important issues in ethnobotany. History The idea of ethnobotany was first proposed by the early 20th century botanist John William Harshberger. While Harshberger did perform ethnobotanical ...

Erythroxylum
''Erythroxylum'' (''Erythroxylon'') is a genus of tropical flowering plants in the family Erythroxylaceae. Many of the approximately 200 species contain the substance 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'' 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 ''Agrias''.

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. The plant is grown as a cash crop in the Argentine Northwest, Bolivia, Alto Rio Negro Territory in Brazil, Colombia, Venezuela, Ecuador, and Peru, even in areas where its cultivation is unlawful. There are some reports that the plant is being cultivated in the south of Mexico, by using seeds imported from South America, as an alternative to smuggling its recreational product cocaine. It also plays a role in many traditional Amazonian and Andean cultures as well as the Sierra Nevada de Santa Marta in northern Colombia. The cocaine alkaloid content of dry ''Erythroxylum coca'' var. ''coca'' leaves was measured ranging from 0.23% to 0.96%. Coca-Cola used coca leaf extract in its products from 1885 until about 1903, when it began using decocainized leaf extract. Extraction of cocaine from coca requires several sol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mirabilis (plant)
''Mirabilis'' is a genus of plants in the family Nyctaginaceae known as the four-o'clocks or umbrellaworts. The best known species may be ''Mirabilis jalapa'', the plant most commonly called four o'clock. There are several dozen species in the genus, of herbaceous plants, mostly found in the Americas. Some form tuberous roots that enable them to perennate through dry and cool seasons. They have small, often fragrant, deep-throated flowers. Although best known as ornamental plants, at least one species, ''mauka'' ('' M. expansa''), is grown for food.
