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).

DistributionEdit

Plants in this genus are distributed through out tropical and subtropical Americas, growing as epiphytes, although some are lithophytes or terrestrials.

DescriptionEdit

The genus was first described by O. Swartz in 1800 in Kungliga Svenska Vetenskapakademiens Avhandlingar.

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.

CultureEdit

Grow in cool to warm conditions with moderate to bright light. Water the plant right before the potting mix starts to dry. Plants should be potted in a well drain medium such as medium fir bark.

NamingEdit

Its name is derived from the Greek word "onkos", meaning "swelling". This refers to the callus at the lower lip.
