Common Name The Curled Odontoglossum

Flower Size 3" to 4" [7.5 to 10 cm]

A medium sized, cool to cold growing epiphytic species from Colombia, found at altitudes of 2000 to 3000 meters in the western slopes of the Cordillera Oriental with broadly ovoid or oblong-ovoid, ancipitous, pseudobulbs carrying 2 apical, suberect, linear-lanceolate, acute leaves that narrow below into a long, narrow, conduplicate Petiole like base and has a varied blooming season, but most often in winter, with fragrant, variable in color and size flowers on an axillary, to 1 1/2' [45 cm] long, many [8 to 20] flowered inflorescence with a racememe at the upper third with a few short basal branches that comes from the side of the newest forming pseudobulb. They require cool, well watered, humid conditions, with medium to heavy shade to thrive and after growth has slowed in the fall they need a slight lessening of water and fertilizer. This species is used often in improving odontoglossum hybridizing.
