In his 1993 monograph, Peter Boyce treats A. concinnatum as a
separate species, as does the RHS
(http://rhs.org.uk/rhsplantfinder/plantfinder.asp/).

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.

Hi,

I'm still trying to finish the thumbnails and consolidate them on pages and
was working on Arum which I know very little about. Kew has listed Arum
concinnatum as the accepted name for Arum italicum var. maroratum and Arum
italicum subvar. marmoratum. Giorgio has added a picture of plants he
calls Arum italicum ssp. marmoratum to our wiki. Since he lives in Italy
where it grows perhaps the name is uses is accepted in Italy if not by Kew.
Do any of you Aroid fans have advice about how we should label it on the
wiki. Thanks.
