Common Name The Golden Oncidium

Flower Size 1.6" [4 cm]

Found in Ecuador, Peru and Bolivia at elevations around 1200 to 1900 meters as a medium to just large sized, cool growing epiphyte with tapered, cylindrical, laterally compressed, longitudinally grooved pseuodbulbs enveloped partially by several, imbricating, lowermost leaf-less uppermost leaf-bearing sheaths carrying 2, apical, narrow, elliptic, acute, conduplicate below into the short petiole-like base leaves that blooms in the spring on a basal, to 39" [to 100 cm] long, paniculate, many flowered inflorescence that arises from the axil of the upper leaf-bearing sheath carrying many, short, few flowered branches.

Very closely related to if not synomonous with Oncidium trilobum, I have left them separate for now. If they are the same orchid then this name would take prescendence.

Synonyms Odontoglossum aurarium (Rchb.f.) Garay 1970; Odontoglossum mapiriense Mansf. 1934
