Monkey puzzle trees are quite interesting both because of their unusual crisscross branches and because they're conifers native to the Southern hemisphere. They're not the only conifers from the Southern Hemisphere, but conditions in the southern temperate zones have almost certainly shaped them into what they are now. In any case, as they're endangered, may they soon be unendangered.
It's theorized that they're spiky branches evolved as a defense against dinosaurs. Crazy to think about how aspects of such a long-ago world are still with us today.
