This is a lot more common in the DB than I'd like to admit. I have a script that I ran a couple days ago that looked for duplicates and found several hundred plants that seem to be duplicates - two (or more) plants with the same genus and cultivar. Sometimes the species differs and sometimes the spelling is just slightly off (as in your example plant above).
I'm grappling in my mind what should be the right solution here. Probably I'm going to make a report that is accessible for everyone to see, so we can start looking through the list and just delete the duplicates.
