Maple syrup
Sources
A few other (but not all) species of maple (Acer) are also sometimes used as sources of sap for producing maple syrup, including the box elder or Manitoba maple (Acer negundo), the silver maple (A. saccharinum), and the bigleaf maple (A. macrophyllum). Similar syrups may also be produced from walnut, birch or palm trees, among other sources.
