Description Two lovely Cattleya orchid blossoms . Orchid, (family Orchidaceae), any of nearly 1,000 genera and more than 22,000 species of attractively flowered plants distributed throughout the world, especially in wet tropics. The word orchid is derived from the Greek word (orchis) for testicle because of the shape of the root tubers in some species of the genus Orchis. These nonwoody perennial plants are generally terrestrial or epiphytic herbs (i.e., growing on other plants rather than rooted in soil). Those attached to other plants often are vinelike and have a spongy root covering called the velamen that absorbs water from the surrounding air. Most species manufacture their own food, but some live on dead organic material (saprophytic) or are helped to obtain nourishment by a fungus living in their roots
