Just to be clear, they are "cultivars", not "clones".
I meant that they are clones in the layman sense that all Donghwan at the moment are clones of each other and all Bulihwan are clones of each other.
I used that term instead of cultivar because the horticultural communities that govern the naming of Neo varieties do not follow the same rules as the orchid communities in the west, and the fact that outside the western orchid communities, a cultivar is not limited to genetically identical individuals: International Code of Nomenclature for Cultivated Plants
