Odontoglossum is a genus of cool-growing, high-elevation Andean sympodial epiphytes with flattened pseudobulbs and showy, often crisped and patterned flowers. Many botanists now sink Odontoglossum into Oncidium, but it is retained here horticulturally. The plants require cool, humid, buoyant conditions year-round.
