In fact, the only pentaploid entity which is a part of the species Tulipa clusiana is the original clone grown in western gardens for over four hundred years and which has been growing in the wild for who knows how long before that.

> I don't have a copy of the Kew monograph to check, but I'll bet that the concept of Tulipa clusiana presented there is the same concept of that species which has existed since DC named the species. But the contemporary concept is different, although you might never guess it from the way that concept is sometimes expressed in the nomenclature.
