After this was posted,
the original was fixed. If you look at the one tree that is now not covered up by the exploded view, you will see how it maintains its basic non-expanding (though in this case, curved) shape going into the ground. Also, it is possible that the bulbous bases one sometimes sees on palm trees might have been covered up at the shoot for aesthetic reasons.
But now that I look at the picture a little more, I realize that any tree that is that close to her (as would need to be in that particular location) would be pretty small. So I am really not sure what it is.
