I'm not a taxonomist, nor do I play one on TV. My understanding is that, at its basic level, taxonomy is simply a method of organization designed to help us better understand the relationships between plants (and animals).
The taxonomists of the 1800's created an aura of glory surrounding the naming of a 'new' genera. This quest continued, with progressively more and more splitting. Much of this did not add to the understanding of the relationship of the new genera to existing ones because the taxonomists in questions chose the glory of a new genera over the practical value of defining sections. A good example is Bulbohpyllum section cirrhopetalum. This has been batted across the net for over 100 years. As more intermediate species were discovered, it became fairly obvious that there is no clear demarkation between cirrhopetalums and other bulbophyllums. Size and color may be 'apparent' differences to laymen, but taxonomists know they are not a valid basis for splitting genera. Homo sapiens... big'uns, little'uns, dark'uns, light'uns - all the same genera and species. Taxonomy is an arena for scientific debate. Theories will be batted back & forth with the occasional ball flying into the stands and nary an impartial judge to declare a winner. My personal observations of the game ... plants can't read, and knowing the latest score does not make you a better grower. But I still enjoy being a spectator.
