Yes, there is. G. ornata is generally smaller, tighter growing and there  are other distinctions.....

It certainly is a bit confusing nowadays. I used (50 years ago) to have distinct plants of each of the above but in the last years there have been so many named and un-named hybrids released onto a grateful but confused public that the distinctions have become very blurred. Mostly now I work on the principle that any gentian (of that "type") is a good gentian and don't worry too much about what's what. ???
