An interpretation of the araucaria tree or common name: "monkey puzzle tree" that lines the remote roads to the Yacui private reserve in Argentina. I had asked our naturalist Leandro about the odd looking tree casually on the road trip. A couple hours later we pulled off the road. He found a fallen branch and gave it to me to see up close. The tree is actually endangered today and is now protected under Appendix I of CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora).
