Sycamore - "The sycamore is full of drinkable sap, read water when you need it." Tap like a maple. "If the tree has single seed pod, it is the sycamore. If there are two seed pods together, it’s a London planetree. If there are 3-5 seed pods, it is an Oriental planetree which has the seed pods hanging like beads. Those seed pods when dry have a coating of tiny hairs and can irritate air passages, so handle them carefully. However, that same hair makes excellent tinder."
