Common Name The Three-Lobed Oncidium

Flower Size 2" [5 cm]

Found in Peru and Bolivia in wet montane forests at elevations of 250 to 1600 meters as a large sized, hot to cool growing epiphyte with a short rhizome carrying an ovoid, flattened, sulcate pseudobulb enveloped basally by distichous, foliaceous sheaths and carrying 2 apical, strap-shaped, green leaves that has a basal, arcuate, weakly paniculate, 3'4" [100 cm] to 10' [300 cm] inflorescence arising on an mature pseudobulb from the lateral leaf axils and occuring in the summer.

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

Synonyms *Odontoglossum trilobum Schlechter 1921
