This Arum discussion is getting interesting. 

I grow a clump of Arum here in Maryland which has long puzzled me. It came
as Arum italicum. The plants - in leaf  and inflorescence - are similar in
size to typical Arum italicum although the leaves are basically plain green
with irregular and sparse whitish-gray specks - one of the plants in this
group has black specks instead of gray specks on the leaves. The spathe is
greenish gold  with a slight purple flush at the base on the inside. The
spadix is pale brownish yellow. 

What makes this group of plants (there is more than one clone) very distinct
is that although they produce foliage in the autumn, that foliage always
dies during the winter and is replaced by new foliage in the late winter.
They have been in the garden for years and seem fully hardy.

Whatever this is, it's much bigger than what I grow as Arum maculatum. 

Here's a view of some of them in bloom and in leaf; they are labeled Arum
incertae sedis in this gallery:

Does this look familiar to anyone? 

Now to change topics a bit: there is another Arum event about to take place
here. A plant received as Arum korolkowii in 2004 is finally going to bloom.
This grows in a cold frame - I think the foliage would not have a chance
during the winter exposed to the air. I'll post more comments about this one
