Despite their long evolutionary history on Earth, the extant orchid diversity is also inferred to have originated during the last 5 million years, [28] with the American and Asian tropics as the geopgraphic areas exhibiting the highest speciation rates (i.e., number of speciation events per million years) on Earth.
Orchis is a genus in the orchid family (Orchidaceae), occurring mainly in Europe and Northwest Africa, and ranging as far as Tibet, Mongolia, and Xinjiang. [1] The name is from the Ancient Greek ὄρχις orchis , meaning "testicle", from the appearance of the paired subterranean tuberoids .
Pyramid-like orchid in Greece. Orchis (Ancient Greek: Ὄρχις, romanized: Órkhis, lit. 'testicle, orchid' [1] [2]) is often claimed to be a minor character in Greek mythology whose transformation is the origin of the orchid flower. However, Orchis's existence and myth does not seem to be attested in classical times.

It reflects the considerable progress in orchid taxonomy that had been made since Dressler published his classification in 1993. In the 1990s, orchid taxonomy began to be influenced by molecular phylogenetics based on DNA sequences. The first molecular phylogenetic study to include a substantial sample of orchids was published in 1999. [12]
[3] [4] Common names for plants in this genus include dancing-lady orchid [5] and golden shower orchid. A 2008 molecular phylogenetic study labeled the Oncidium alliance "grossly polyphyletic ." [ 6 ] In the same year, the American Orchid Society labeled the genus a "dumping ground". [ 7 ]
Dendrobium is a genus of mostly epiphytic and lithophytic orchids in the family Orchidaceae. It is a very large genus, containing more than 1,800 species that are found in diverse habitats throughout much of south, east and southeast Asia, including China, Japan, India, the Philippines, Indonesia, Australia, New Guinea, Vietnam and many of the islands of the Pacific.
