The Flora of Colombia is characterized by over 32,000 species of green plants. [1]
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.
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. quindiuense is the only palm that grows at such high altitudes in Colombia and is the tallest monocot in the world.
Colombia has the largest number of endemic species (species that are not found naturally anywhere else) worldwide. About 10% of the species in the world live in Colombia. Some determinant factors in the distribution range of the species are the wide diversity of habitats available due to the variety of altitudes, weather conditions, temperatures, soils and sunlight on the coasts, in the Andes [2] and in the rainforest lowlands.
Endemics can easily become endangered or extinct due to their restricted habitat and vulnerability to the actions of man, including the introduction of new organisms.
According to the Colombian Ministry of Environment, the following ecoregions have the highest percentage of botanic endemic species:
Many of the Colombian trees are endangered species due to the high quality of the woods and timber industry exploitation (such as Colombian oak Quercus humboldtidiana and Colombian mahogany) and as source of tanning substances for the leather industry (such as mangrove and Encenillo tree Weinmannia tomentosa ). Some tree species described in Colombia are:
There are over 3900 Genera in the flora of Colombia [1] Some representational Genera are included below.
Colombia has the largest number of orchids in the world. Among others:
Orchids are plants that belong to the family Orchidaceae, a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Orchids are cosmopolitan plants that are found in almost every habitat on Earth except glaciers. The world's richest diversity of orchid genera and species is found in the tropics.
The taxonomy of the Orchidaceae (orchid family) has evolved slowly during the last 250 years, starting with Carl Linnaeus who in 1753 recognized eight genera. De Jussieu recognized the Orchidaceae as a separate family in his Genera Plantarum in 1789. Olof Swartz recognized 25 genera in 1800. Louis Claude Richard provided us in 1817 with the descriptive terminology of the orchids. (See External links below). The next step was taken in 1830-1840 by John Lindley, who recognized four subfamilies. He is generally recognized as the father of orchid taxonomy. The next important step was taken by George Bentham with a new classification, recognizing subtribes for the first time. This classification was first presented in a paper that Bentham read to the Royal Society in 1881. Then it was published in 1883 in the final volume of Genera Plantarum. The next great contributors were Pfitzer (1887), Schlechter (1926), Mansfeld (1937), Dressler and Dodson (1960), Garay (1960, 1972), Vermeulen (1966), again Dressler (1981). and Burns-Balogh and Funk (1986). Dressler's 1993 book had considerable influence on later work.
Wilhelm (Guillermo) Kalbreyer (1847–1912) was a German plant collector who was sent by James Veitch & Sons of Chelsea, London to collect new plants in West Africa and South America.
