Hi Mary Sue,

This is a difficult topic.

I grow here at home A. italicum. A. italicum subsp. italicum has got yellow veining on the leaves (by Deni Bown: Aroids and Joghn E. Bryan: Bulbs I.) The form called 'Pictum' or 'Marmoratum' has got very strong white veining. It should be called: A. italicum subsp. italicum 'Pictum'  (Bown?).

There is a book of Hungarian Flora, which says incorrectly, that A. maculatum is the synonymon of A. italicum. A. italicum is not fully hardy here (Z5a).

Other subspecies, different from subsp. italicum hasn't got veining on the leaves.

That's all I know, hope this helps...

Try to reach Peter boyce, hi is an expert of Aroids. If you do not know his contacts write me privately.

  Subject: [pbs] Arum


  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.
