When Oncidium orchids were introduced to Europe in the 1830s, the flowers were thought to resemble ladies in ruffled skirts, inspiring their common name. Dancing lady orchids are usually found growing on the trunks or branches of rain forest trees througout subtropical and tropical America, from sea level to high mountain areas. These plants differ widely in habit, but are easily recognized by their slender branching sprays with many small flowers, generally in shades of yellow and brown. Their pleasant scent makes them a desirable houseplant.
