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!
