So basically a plant can have several different names, sometimes just a reintroduced name to make it look like a "new" or "rare" specimen (so we never really know what we actually have) AND it could be a tissue culture that we never even knew we had!?
What a tangled web!
It really does make me think of what you said about the possibility of using tissue culture for real rare and endangered plants. I hope somebody skilled gets around to that one of these days
