Plant
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ...

Rubiaceae
The Rubiaceae are a family of flowering plants, commonly known as the coffee, madder, or bedstraw family. It consists of terrestrial trees, shrubs, lianas, or herbs that are recognizable by simple, opposite leaves with interpetiolar stipules and sympetalous actinomorphic flowers. The family contains about 13,500 species in about 620 genera, which makes it the fourth-largest angiosperm family. Rubiaceae has a cosmopolitan distribution; however, the largest species diversity is concentrated in the tropics and subtropics. Economically important genera include ''Coffea'', the source of coffee, '' Cinchona'', the source of the antimalarial alkaloid quinine, ornamental cultivars (''e.g.'', '' Gardenia'', ''Ixora'', ''Pentas''), and historically some dye plants (''e.g.'', ''Rubia''). Description The Rubiaceae are morphologically easily recognizable as a coherent group by a combination of characters: opposite or whorled leaves that are simple and entire, interpetiolar stipules, tubu ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecuador
Ecuador ( ; ; Quechua: ''Ikwayur''; Shuar: ''Ecuador'' or ''Ekuatur''), officially the Republic of Ecuador ( es, República del Ecuador, which literally translates as "Republic of the Equator"; Quechua: ''Ikwadur Ripuwlika''; Shuar: ''Ekuatur Nunka''), is a country in northwestern South America, bordered by Colombia on the north, Peru on the east and south, and the Pacific Ocean on the west. Ecuador also includes the Galápagos Islands in the Pacific, about west of the mainland. The country's capital and largest city is Quito. The territories of modern-day Ecuador were once home to a variety of Indigenous groups that were gradually incorporated into the Inca Empire during the 15th century. The territory was colonized by Spain during the 16th century, achieving independence in 1820 as part of Gran Colombia, from which it emerged as its own sovereign state in 1830. The legacy of both empires is reflected in Ecuador's ethnically diverse population, with most of its mill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Ecuador
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pentagonia (plant)
''Pentagonia'' is a genus of over 40 species of plants in the Coffee or Gardenia family ( Rubiaceae}. ''Pentagonia'' species are native to Central America and northern South America, and grow in moist tropical forests below 900m. The genus was first described by George Bentham in 1845. The genus is noteworthy for its opposite pairs of huge leaves in a variety of shapes including entire, shallowly or deeply lobed, and even pinnate. These leaves can, in the case of a recently discovered species, be up to four feet (1.2 meters) long not including the six inch (15 cm) petiole, and up to 2.5 feet (76 centimeters) in width. Species , Plants of the World Online accepted the following species: *'' Pentagonia amazonica'' (Ducke) L.Andersson & Rova *'' Pentagonia angustifolia'' C.M.Taylor *'' Pentagonia australis'' C.M.Taylor & Janovec *'' Pentagonia baumannii'' Cornejo & Rova *'' Pentagonia bocataurensis'' Dwyer *'' Pentagonia bonifaziana'' Cornejo *'' Pentagonia breviloba'' L.Ande ...

Endangered Plants
As of September 2016, the International Union for Conservation of Nature (IUCN) lists 3654 endangered plant species. 17% of all evaluated plant species are listed as endangered. The IUCN also lists 99 subspecies and 101 varieties as endangered. No subpopulations of plants have been evaluated by the IUCN. For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of exintction". An even higher risk is faced by ''critically endangered'' species, which meet the quantitative criteria for endangered species. Critically endangered plants are listed separately. There are 6147 plant species which are endangered or critically endangered. Additionally 1674 plant species (7.6% of those evaluated) are listed as '' data deficient'', meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
