Food for thought... RE: your point about Sarracenia being all one 
species... ARE all sarrs a single species?  I think not, but if I'm not 
mistaken, ALL sarrs are interfertile, and in many cases where their 
microranges overlap, natural hybrids occur...  hybrid swarms of 
rubra/leuco/etc in Fla. panhandle are another interesting occurrence...  
I think it would be impossible to ever find a "pure species" in this area 
(this subject has been covered to some extent in the literature, I think)
