I would say that a big part of the issue -- for me at least -- Magnus, is Kew putting out a name change and then changing it yet again just a short time later. It calls into question their position as an "authority" as they obviously cannot make up their little minds. If the argument is: "these back and forth name changes is because there is so much DNA information still emerging" then the intelligent course of action would be to complete the analysis and THEN announce what changes will be made.
Even more ludicrous is the blatant stupidity of some of the resulting name changes. Particularly amongst the hybrids, it is evident in the new name that some taxomonist is just trying to get their name on plant. If the plants making up an Iwanagara for instance get renamed, fine -- but that does not mean the name Iwanagara necessarily needs to be discarded (especially in favor of that of some self aggrandizing taxomonist).
Also I do recall one of our members mentioning that a great deal of the current confusion is the result of internal politics.
The result of all this grand idiocy is the ticking off of the general orchid public to the point that many have no interest in what these people have to say nor any intent on following the changes in practice.
