Shoot, taxonomists disagree more about DNA results than they do about morphological classification! Both methodologies are incredibly subjective. For example, Brazilian Laelias were lumped into Sophronitis for a while and then lumped further into Cattleya based on DNA. And it was the same taxonomist that made both changes!
