Edible Saps

So we all know about maple syrup but what other kinds of trees produce syrup?

Maples: (Genus: Acer)

• Sugar Maple (Acer Saccharum)
• Black Maple (Acer Nigrum)
• Red Maple (Acer Rubrum)
• Silver Maple (Acer Saccharinum)
• Norway Maple (Acer Platanoides)
• Boxelder (Acer Negundo)
• Bigleaf Maple (Acer Macrophyllum)
• Big Tooth Maple (Acer Grandidentatum)
• Rocky Mountain Maple or Douglas Maple (Acer Glabrum)
• Painted Maple (Acer Pictum)

Birches: (Genus: Betula)

• Paper Birch (Betula Papyrifera)
• Yellow Birch (Betula Alleghaniensis)
• Black Birch (Betula Lenta)

Walnuts: (Genus: Juglans)

• Butternut or White Walnut (Juglans Cinerea)
• Black Walnut (Juglans Nigra)
• Heartnut (Juglans Ailantifolia)

Possibly: (It seems possible but there is little data regarding the exact type of tree, nor is it commonly done)

• American Sycamore (Platanus Occidentalis)
• American Hophornbeam (Ostrya Virginiana)
• American Basswood (Tilia Americana)
• Elm Trees (Genus: Ulmus)

This is by no means a definitive list, as there could be more syrup producing trees, that remain undocumented.  This is merely a list of some of the more common trees tapped.
