Orchid

Orchid


Taken outiside Mebourne's Univeristy Engineering building. There were some orchids there amond the tall grasses. I tried to take from the front but gives a very ugly shape of like a + sign. I notice that ti has this purple bud by its side and decided that it will be a more interesting angle. Orchid is Singapore's national flower.



Orchids (Orchidaceae family) are the largest and most diverse of the flowering plant (Angiospermae) families, with over 800 described genera and 25,000 species. Some sources give 30,000 species, but the exact number is unknown since classification differs greatly in the academic worldAbout 800 new species are added each year. Orchids, through their interactions with pollinators and their symbiosis with mycorrhizae fungi, are considered by some, along with the grasses, to be examples of the most advanced (derived) floral evolution known.

One orchid genus, Vanilla, is commercially important, used as a foodstuff flavoring, the source of vanilla. The underground tubers of terrestrial orchids are ground to a powder 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).

Orchids get their name from the Greek orchis, meaning "testicle", from the appearance of subterranean tuberoids of the genus Orchis. The word "orchis" was first used by Theophrastos (372/371287/286 BC), 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.

 This is an Iris, not an orchid. The flag Iris is the national flower
of France, & is the origin of the fleur de lis symbol, which incidentally is part
of the [Trinity] College emblem!
