Oncidium

Oncidium, abbreviated as Onc in horticultural trade, is a genus that contains about 330 species of orchids from the subfamily Epidendroideae of the orchid family (Orchidaceae). This is a complex, difficult genus, with many species being reclassified. Calls are made for splitting this genus into multiple genera.

This genus was first described by Olof Swartz in 1800 with the orchid Oncidium altissimum, which has become the type species. Its name is derived from the Greek word "onkos", meaning "swelling". This refers to the callus at the lower lip.

The flowers of the Oncidium genus come in shades of yellow, red, white and pink. The petals are often ruffled on the edges, as is the lip. The lip is enormous, partially blocking the small petals and sepals.
