A big group of trees were growing at the same habitat than the Salix sp. considered at
The thread "Barrage - Salix sp." in Plant ID forum
but they were clustered together in a zone of the barrage. They are much taller then the other shrubs/trees there (maybe they can reach 10 meters high). The leaves remind me some tropical vegetation, but I have no idea of what can be. unfortunatelly the photos taken showing the whole tree were unfocused and are useless, so I can only add some closer looks. They were fertile and full of pods with seeds inside.
I will appreciate any hint / comment about its classification.
Thanks in advance,
zaca

When and where were these pics taken?

Dear purpleinopp,
The information about the location was given in
The thread "Barrage - Salix sp." in Plant ID forum
since all was at the same habitat. I repeat it below.

It looks like an Albizia. It looks like the A. julibrissin that is ubiquitous in my area, but not sure what species might be found in Portugal, or how one would differentiate between them. The trees here (31ยฐ N, if that helps to compare) are not to the seed pod stage yet, still heavily in bloom, though starting to fade in color intensity.

Reminds me of a lot of Mimosa Tree (Albizia julibrissin) or possibly Acacia sp.; one for comparison Silver Wattle (Acacia dealbata)

Reminds me of Acacia dealbata

Both Albizia julibrissin and Acacia dealbata occur in the area and it would be easy if they were in flower! But going with the evidence we have, the seeds match Acacia dealbata more than the Albizia according to pics on the web:

Many thanks to all of you.
Seeing the proposals by purpleinopp, plantladylin and islander, I was in doubt. Finally, the argument by sooby is irrefutable: the seeds are like those of Acacia dealbata.
Best regards,
