Orchids

Orchids are the most cosmopolitan of flowering plant families, found everywhere on Earth except dry deserts and cold glaciers. They are thought to be one of the largest flowering plant families and contain around 25,000 species. They are most numerous in the world's tropical areas where big, showy flowers are produced, although the flowers of species found elsewhere are no less beautiful. Orchids have developed some highly specialized pollination systems, often producing attractively shaped and colourful flowers that sometimes look similar to the insects that pollinate them. Some species of orchid are now very rare.

About

The Orchidaceae are a diverse and widespread family of flowering plants with colorful and fragrant blooms, commonly known as the orchid family. Along with the Asteraceae, they are one of the two largest families of flowering plants, with between 21,950 and 26,049 currently accepted species, found in 880 genera. Selecting which of the two families is larger is still under debate, as concrete numbers on such enormous families are constantly in flux. Regardless, the number of orchid species equals more than twice the number of bird species, and about four times the number of mammal species. The family also encompasses about 6–11% of all seed plants. The largest genera are Bulbophyllum (2,000 species), Epidendrum (1,500 species), Dendrobium (1,400 species) and Pleurothallis (1,000 species).

The family also includes Vanilla (the genus of the vanilla plant), Orchis (type genus), and many commonly cultivated plants such as Phalaenopsis and Cattleya. Moreover, since the introduction of tropical species in the 19th century, horticulturists have produced more than 100,000 hybrids and cultivars.
