Thanks in advance.

 

I'd say Araucaria columnaris, though a fairly tricky one to be certain.

 

Is this one a real Araucaria heterophylla? I took the photo during a vacation in Sicily.

That one looks it, yes.

 

Hi,

I am not familiar with A. columnaris, but have grown A. heterophylla and it is common around here. I'm with Michael, the first three photos do not look like A.heterophylla, but the last one does.

this is Araucaria columnaris without a doubt ,the habit of a columnaris is more compact than norfolk island pines

 

I'm with Graeme on this one. A. heterophylla would be wider spreading than the tree in the photo.
Also, I understand that A. columnaris also develops a leaning habit with age. Nobody knows why exactly.

 

www.conifers.org is a good site re conifers. Took a look there; have to agree it is A. columnaris.

Thank you for posting the images - is an interesting plant.

Do you want to correspond with Wikipedia?

 

A good common name for A. columnaris would be Leaning Tower of Pisa Tree.
