MYSTERY TREE

I am hoping you can help me identify. this tree - it has me stumped. More detail in extras.

It's the last day at the Cortijo, where the retreat has been a perfect balance of stillness and raucous laughter; of time to oneself and excellent company;   of opportunities to practice without the preachy bits.   One the last day I sense the sadness at leaving offset by knowing I am much more able to pick up the cudgels of daily life once more.
