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.
