Orchids are a beautiful and exotic flower.Orchids are among the largest and most diverse of the flowering plant families, with over 800 described genera and 25,000 species, and perhaps another 60,000 hybrids and varieties produced by horticulturists. The Kew checklist "World Checklist of Orchids" gives about 24,000 accepted names. About 800 new species are added each year. There are more orchid species than all vertebrates combined, excluding bony fishes. Orchids, through their floral complexity and their interactions with pollinators and their symbiosis with mycorrhizae, are considered by some to be the culmination of floral evolution. Orchids get their name from the Greek orchis, meaning 'testicle', from the appearance of subterranean tuberoids in some terrestrial species. The word 'orchis' was first used by Theophrastos (371/372 - 287/286 B.C.), in his book "De historia plantarum" (The natural history of plants). He was a student of Aristotle and is considered the father of botany and ecology. Orchids, in their natural habitat, are considered by CITES as threatened or endangered. They are therefore protected. There are a great number of tropical and subtropical orchids, and these are the most commonly known, as they are available at nurseries and through orchid clubs across the world. There are also quite a few orchids which grow in colder climates, although these are less often seen on the market. Species of Orchids
One orchid is used as a foodstuff flavoring, the source of Vanilla. The underground tubers of terrestrial orchids are ground up and used for cooking, such as in the hot beverage salep or the so-called "fox-testicle ice cream" salepi dondurma. The scent of orchids is frequently used by perfumists (using Gas-liquid chromatography) to identify potential fragrance chemicals. With these exceptions, orchids have virtually no commercial value other than for the enjoyment of the flowers (see also Botanical orchids). The family of orchids is remarkably diverse. The plants found in "casual" culture, such as Phalaenopsis, Cattleya, Dendrobium, and so forth, represent a tiny fraction of the thousands of varieties of orchids. Also within the Orchidaceae are "leafless" orchids, which often appear as nothing more than masses of roots, achlorophyllous orchids that are entirely reliant upon their mycorrhizal symbiont for their nutrition, "jewel" orchids with foliage that is as pretty as their flowers, and so many others that are capable of affecting the most dedicated of growers very deeply. Ranging in size from tiny moss-like Pleurothallis species to massive Grammatophyllums in New Guinea, their beauty and sophistication have captivated many. |
