The Flora of Colombia is characterized by a high biodiversity, with the highest rate of species by area unit worldwide. Over 130.000 species of plants have been described within Colombian territory[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.

The Wax palm was selected as the national tree by the government of Belisario Betancur and was the first tree officially declared as protected specie in Colombia. C. quindiuense is the only palm that grows at high altitudes and is the tallest monocot in the world.
Colombia has the largest amount of endemisms (species that are not found naturally anywhere else) worldwide. About 10% of the species in the world live in Colombia.[2] Some determinant factors In the distribution range of the species are the weather conditions, temperature, humidity and sunlight availability.
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 endemisms:
Many of the colombian trees are endangered species due to the high quality of the woods and timber industry explotation (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 tormentosa).
