Looking for a name II

After some looking around the area where the pods were falling, I found the tree. It's worth repeating that just in a few square meters of this area, there are a number of other trees which I'd like to identify. My friend and neighbor who had given me the name "pajucara" for this particular tree, may have been putting me on, or he was simply showing off some false knowledge that he had learned from his grandfather. Irregardless, the name got me nowhere. I discovered that just about everything under the Brazilian sun is called Pajucara, except for this tree. Next image: the cut tree and a new name.
