Thank you Dave.  I have scanned the amjbot reference.  On this quick reading I 
am not convincied that I should give up the taxonomies I am familiar with.  As 
far as I can tell an identification in the New World of taxonomy requires a 
powerful DNA sequencer and an equally powerful computer that sometimes has to 
run for 30 days without comming to a conclusion.  These are usefull and 
probably essential  tools to try to sort out evolutionary trends, but for 
practical gardners and I suspect for most field ID, they are at best confusing 
and at worst useless.  When I find a plant I do not know, I try to match the 
characteristics I see with descriptions of genus or species based on visible 
characteristics.  I do not see the DNA itself, only the result as expressed in 
the plant's growth and form.   If the Scrophulariaceae is heterogeneous, then 
the newly organized family is not much better - "Therefore, the Plantaginaceae 
can only be vaguely described morphologically."   If there is no improvement in 
the clarity with which a group is defined, then I see no reason to alter 
nomenclature.  Such change does not lead to better communication between 
gardeners (people who use plant names to talk with eachother) and Botanists who 
try to ferret out evolutionary relationships. The Scrophulariaceae to most 
gardeners brings thoughts of lovely plants. Plantaginaceae generally recalls 
the genus Plantago - ubiquitous weeds.
