<i>Coelogyne</i> Genus of orchids

Coelogyne is a genus of 594 species, which are sympodial epiphytes from the family Orchidaceae, distributed across India, China, Indonesia and the Fiji islands, with the main centers in Borneo, Sumatra and the Himalayas. They can be found from tropical lowland forests to montane rainforests. A few species grow as terrestrials or even as lithophytes in open, humid habitats. The genera BolborchisLindl., HologynePfitzer and PtychogynePfitzer are generally included here. The genus is abbreviated Coel. in trade journals.

<span class="mw-page-title-main">Nerolidol</span> Chemical compound

Nerolidol, also known as peruviol and penetrol, is a naturally occurring sesquiterpene alcohol. A colorless liquid, it is found in the essential oils of many types of plants and flowers. There are four isomers of nerolidol', which differ in the geometry about the central double bond and configuration of the hydroxyl-bearing carbon, but most applications use such a mixture. The aroma of nerolidol is woody and reminiscent of fresh bark. It is used as a flavoring agent and in perfumery as well as in non-cosmetic products such as detergents and cleansers. Nerolidyl derivatives include nerolidyl diphosphate and the fragrance nerolidyl acetate.
