Ron, There are several ways to deal w/ duplicates or mis-named plants.
You can post a new thread to the Plants Database Forum http://garden.org/forums/view/...
or you can propose a plant be deleted giving Duplicate or synonym, etc. as a reason
or you can propose a correction to the naming of a plant. There are others as well. I'd recommend posting it to the Forum so that it will be brought to everyone's attention. Besides they're a great group of people. Thanks for the heads up on these plants.
