Common Name The Bird's Beak Oncidium [refers to the shape of the column]

Flower Size 1" [2.5 cm]

A small sized, cold growing epiphytic species from Colombia, Ecuador and Peru found at altitudes of 2000 to 3300 meters in the western slopes of the Cordillera Oriental and blooms in the summer in Bogata' and has ovoid to cylindrical, compressed, unifoliateto trifoliate pseudobulbs with oblanceolate to elliptic-oblong acute or acuminate leaves that blooms mostly in the summer on a erect to pendant, to 20" [50 cm] long, shortly paniculate inflorescence carrying many fragrant, canary yellow flowers and a few interspersed throughout, sterlie star shaped flowers.

CAUTION!!!!CAUTION!!!!This name until recently was thought to describe a Central American, pink flowered, highly fragrant orchid, but in 2010 it was realized that HBK acutally was describing a yellow flowered species from Colombia, Ecuador and Peru that has been commonly been known as O pyramidale, hence the photos above. If you have the pink flowered, Central American species then the true current name is Oncidum sotoanum, please go to that species for the information on it.
