Dear Marek,

The only person who I believe can give you a totally accurate answer on this question is Dr. Goncalves in Brazil.
We had a long discussion on some photos of plants much like these a couple of years ago on aroid-l.
I will offer my OPINION that the plants in your photos are X. sagittifolium because of the all-green blades, I recall that the ones I.D.`d by Eduardo a while ago also had darkened petioles, but the leaf blades were a ''clean'' green like those in your photos, unlike the blades of X. violacium/nigrum in which there are traces of the purple color.   The spathes will also reflect these colors..

Subject: [Aroid-l] A Xanthosomatic problem

I got 4 photos of a Xanthosoma. They were sent to me as X. sagittifolium,
but I'm deceived by the dark petioles, they look more like X. violaceum or X. nigrum.
The photos were taken in two botanic gardens in Poland.
The horizontal ones (with Pistia on the right) in one garden,
these vertical in another garden:
I'd be very grateful for any help.
