This is a "Ceiba", the sacred tree of the Mayans.
I took this picture in Palenque, Chiapas, Mexico...on July 22nd 2013, in one of the gardens of the Chan-Kah resort (17.492035? N, 92.018959? W)
The camera, an LG Nexus 4 used the stock camera app. and yes, it is a Panorama, a vertical panorama, as to be able to capture (mostly) the
entire ancient tree in the photo.
