I thought of Sharry Baby looking at your pictures. The thing about that name is Sharry Baby is a grex consisting of more than one cultivar - the way you have listed this plant also implies 'Redolence' is a cultivar in a grex called Heaven Scent.

There is nothing wrong with the name! (apart from the strange thing that happens the world over, that is Sharry becomes Sherry).

Oncidium Sharry Baby is one parent of Oncidium Heaven Scent
