As far as changing all your labels, Ken, why bother? Nobody else seems to be. Even growers selling at shows have the old names on most of their plants here. If you get them from your wholesaler with the old names, I say leave 'em.
If you have a customer who is serious enough to want to show their plant (in a few years when they're big enough) they will also be knowledgeable enough to re-label it themselves. If you just put the alternate (new) names on your website entries - and I'd put the old names on there too, for those of us who don't know or care about the new ones - that should make everyone happy.
I mean, really, how many of us knew what a Rmy. was before Jim looked it up on OrchidWiz? Now . . . I'm going to have to go back a page and find what he said it was, since I've slept since then . . .
Rhynchosomethingorother? It's in the same vein as Whattheheckia, right?
