Oncidium pyramidale is now considered a synonym of
Oncidium ornithorhynchum.
The pink flower often labelled as
Oncidium ornithorhynchum is actually
Orchid (Oncidium sotoanum). This is a result of the wrong name being applied to the species for decades and only in the past few years has it been realised that the original type for the species is actually the same as
Oncidium pyramidale.
