Hi, John.
      First, Lycopersicon is probably really just a sister group to some other 
small species group within Solanum, not to Solanum as a whole  (i.e., 
recognizing Lycopersicon as a separate genus instead of as a subgroup of 
Solanum  makes Solanum paraphyletic).  I'm sure there have been some pretty  
recent symposium volumes published on systematics of Solanaceae-- I saw one in 
the herbarium just recently.  I can help you look for it if you like.   Leave 
a note in my mailbox or e-mail me if you want to get together
