Common Name The Two-Colored Odontoglossum

Flower Size 1 1/2" [3.75 cm]

Found in Bolivia and Peru in wet montane forests at elevations around 3710 meters as a small sized, cool to cold growing terrestrial with elliptic or oblong-elliptic, compressed pseudobulbs subtended by several basal, scarious sheaths with lanceolate-elliptic, acute leaves that is attenuate to the canaliculate petiole and has carinate mid-vein that blooms on an erect, basal, 9 1/4" to 20" [23 to 50 cm] long, several flowered inflorescence arising on a amature pseudobulb occuring in the spring and summer in nature. Cited as a synonym of Odontoglossum aureum but I feel there are sufficient diffeences to keep them apart.
