Mary Sue: Thanks for the great expose detailing what catalog writers go through in trying use correct nomenclature. I can name several plants that we spent far more time researching the nomenclature than the sales of the plant would ever produce. I wonder when the taxonomic world will devise a review committee system that officially accepts or rejects name changes. I'd say this is long overdue!
