I am trying to identify these two wonderful trees. (the 2nd and 3rd photo is of the same tree) The first tree (on the left) is a thorny barked tree which I came across in Malaga, Spain.The Bark looks pale green, but I think it's just moss. I checked out Ceiba speciosa - Floss Silk Tree but I don't think that's it. Sorry I never shot the foliage. The other smooth barked tree with the enormous root system was found in Cartegena Spain. Thanks!
