The admins also only feel comfortable adding orchid species to the database. Other entries have to be "doctored" to be listed in our database. The problem is that the naming conventions for orchids do not agree with the rules of our database. We have no appropriate place for the name of the grex. It can't be part of the botanical name because that's confined to the genus and species. It therefore is entered on the line for the cultivar name, and our system automatically encloses cultivar names in single quote marks. I don't know the solution. Should the grex be listed as part of the common name for the cultivar?
As for the Cattlianthe/Guarisophleya issue, neither is the accepted name of a genus although Guarisophleya was listed as one in our database 5 years ago. I have therefore deleted the entry for Guarisophleya. Checking the grex at the RHS is no help as long as the orchid naming conventions disagree with the way our database works.
