  In his 1993 monograph, Peter Boyce treats A. concinnatum as a 
  separate species, as does the RHS 

  Also, Peter Boyce has recently revised his opinion on A. italicum, 
  concluding that subsp. italicum and subsp. neglectum cannot be 
  separated. I'm sending Mary Sue a pdf of his article in The Plantsman 
  magazine (March 2006) in which he explains this. Unfortunatately, I 
  cannot make it available to all as this is copyright material and I 
  only have permission for limited private circulation.

  'Marmoratum' is now treated as a cultivar.
