More gorgeous stuff, Fred!!
Yes, according to KEW the accepted name is Laelia superbiens, Schomburgkia superbiens is one of the official synonyms.
Guess what, I bought it as Schomburgkia and in my mind it will stay Scomburgkia!
Now if I were to take that plant to a Show where it will be judged, I will happily call it by its accepted name. Or, if this plant would be used in hybridization, yes, the latest accepted name will be used.
In the meanwhile, I am a hobbyist, not a professional grower.....
