In going back and re-reading this thread, I want to caution you to not use the synonym field for anything except synonym botanical names.
Additional cultivar names should go in the cultivar fields. That's what they are for.
The synonyms are only intended for genus/species synonyms.
Now that we're finished migrating to the new server, I can move down to my next highest priority items, which are finishing up all my recently added TODO items for the database, especially this "Browse by genus" issue.
