AdvancedOdontoglossum
A cool-growing orchid from South American highlands with beautifully patterned flowers on long spikes.
About
Odontoglossum, first named in 1816 by Karl Sigismund Kunth, is a formerly accepted genus of orchids that is now regarded as a synonym of Oncidium. Several hundred species have previously been placed in Odontoglossum. The scientific name of the genus is derived from the Greek words odon (tooth) and glossa (tongue), referring to the two tooth-like calluses on the base of the lip. Species formerly placed in this genus are cool to cold growing orchids to be found on open spots in the humid cloud forest at higher elevations from Central- and West South America to Guyana, with most species around the northern Andes. The abbreviation for this genus is Odm. in the horticultural trade. Many of the species formerly placed in the genus are in great demand with orchid lovers because of their spectacular and flamboyant flowers.
