Aimé Bonpland
Aimé Jacques Alexandre Bonpland (; 22 August 1773 – 11 May 1858) was a French explorer and botanist who traveled with Alexander von Humboldt in Latin America from 1799 to 1804. He co-authored volumes of the scientific results of their expedition. Biography Bonpland was born as Aimé Jacques Alexandre Goujaud in La Rochelle, France, on 22, 28,. or 29 August 1773. His father was a physician and, around 1790, he joined his brother Michael in Paris, where they both studied medicine. From 1791, they attended courses given at Paris's Botanical Museum of Natural History. Their teachers included Jean-Baptiste Lamarck, Antoine Laurent de Jussieu, and René Louiche Desfontaines; Aimé further studied under Jean-Nicolas Corvisart and may have attended classes given by Pierre-Joseph Desault at the Hôtel-Dieu. During this period, Aimé also befriended his fellow student, Xavier Bichat. Amid the turmoil of the French Revolution and Revolutionary Wars, Bonpland served as a surge ...

Taxa Named By Aimé Bonpland
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ...

Plants Described In 1809
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 ability ...

Flora Of Panama
Panama is a country located in Central America, bordering both the Caribbean Sea and the Pacific Ocean, between Colombia and Costa Rica. Panama is located on the narrow and low Isthmus of Panama. This S-shaped isthmus is situated between 7° and 10° north latitude and 77° and 83° west longitude. Panama encompasses approximately . It is long, and between wide. Geology The geology of Panama is extremely complicated. The land was formed by interactions of several tectonic plates over the past 10 million years. Elevation The dominant feature of Panama's landform is the central spine of mountains and hills that forms the continental divide. The divide does not form part of the great mountain chains of North America, and only near the Colombian border are there highlands related to the Andes, Andean system of South America. The spine that forms the divide is the highly eroded arch of an uplift from the sea bottom, in which peaks were formed by volcanic intrusions. The we ...

Flora Of Colombia
The Flora of Colombia is characterized by over 28,000 species of green plants. National Flower of Colombia The national flower of Colombia is the orchid ''Cattleya trianae'' which was named after the Colombian naturalist José Jerónimo Triana. The orchid was selected by botanist Emilio Robledo, in representation of the Colombian Academy of History to determine the most representative flowering plant of Colombia. He described it as one of the most beautiful flowers in the world and selected ''Cattleya trianae'' as National symbol. National Tree of Colombia The national tree of Colombia is the palm ''Ceroxylon quindiuense'' (Quindío wax palm) which was named after the Colombian Department of Quindío where is located the Cocora valley, the only habitat of this restricted range species. The Quindío wax palm was selected as the national tree by the government of Belisario Betancur and was the first tree officially declared as a protected species in Colombia. ''C.quindiuens ...

Trees Of Northern South America
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically ...

Quercus
An oak is a tree or shrub in the genus ''Quercus'' (; Latin "oak tree") of the beech family, Fagaceae. There are approximately 500 extant species of oaks. The common name "oak" also appears in the names of species in related genera, notably '' Lithocarpus'' (stone oaks), as well as in those of unrelated species such as ''Grevillea robusta'' (silky oaks) and the Casuarinaceae (she-oaks). The genus ''Quercus'' is native to the Northern Hemisphere, and includes deciduous and evergreen species extending from cool temperate to tropical latitudes in the Americas, Asia, Europe, and North Africa. North America has the largest number of oak species, with approximately 160 species in Mexico of which 109 are endemic and about 90 in the United States. The second greatest area of oak diversity is China, with approximately 100 species. Description Oaks have spirally arranged leaves, with lobate margins in many species; some have serrated leaves or entire leaves with smooth margins. ...

Fuertes's Parrot
Fuertes's parrot (''Hapalopsittaca fuertesi''), also known as the indigo-winged parrot, is a parrot which has a highly restricted range on the west slope of the Central Andes of Colombia. It is classified by the IUCN as being critically endangered. It is threatened by deforestation. Description Fuertes's parrot is about 24 cm longdel hoyo, J. Elliott, A. and Sargatal, J. (1997) Handbook of the Birds of the World Volume 4: Sandgrouse to Cuckoos Lynx Edicions, Barcelona and is green with indigo wing feathers, red shoulders, and a blue crown. The bird's pale ivory bill has chestnut feathers at the base. It was rediscovered in 2002 after an absence of 91 years on the slopes of a volcano in Colombia.
