Dear Friends,
	Although I have vaguely followed the discussion, there is an 
air of blind leading blind.

	The range of variation from a hybrid cultivar to a valid 
species of hybrid origin is the topic of long weeks of discussion in 
any college taxonomy course.  Not for twitter replies.

	I suggest that if anyone is seriously interested, to look at 
the appropriate heading in "International Code of Botanical 
Nomenclature"   or "International Code of Nomenclature for Cultivated 
Plants". Versions of both are available on line, although not the 
newest of either. A similar code is available for Zoological 

	There are numerous validly described and named species that 
are now known to be of natural hybrid origin. Jane McGary mentions a 
small fraction. Each case is the result of careful consideration.

	I don't even know where to start here, but do read something 
relatively factual instead of making guesses and going off on
