The paper tree is a renewable source of paper. It has a symbiotic relationship with the needle vine, which grows needles that can be used as a writing utensils with paper from the tree. To harvest paper from the paper tree, one of its 3m diameter, 6mm thick leaves is removed and dried. As it dries, it loses most of the green color and separates into dozens of very thin layers. These sheets can then be cut to convenient sizes. Needles from the needle vine can then be used to write on the resulting paper.
