9. Differentiating the maples by leaf 

10 maples identified in the Glebe: sugar, Norway, crimson king (a Norway maple),
Schwedler (a Norway maple), silver, red, Manitoba, Japanese, Amur, Tatarian.
6 have distinctive leaves, either shape or colour:

  • Amur maple - small leaves, barely maple-like

  • Tatarian maple - a type of Amur with leaves that are unlobed or almost so

  • Japanese maple - very finely cut and burgundy colour

  • Silver maple - finely cut

  • Manitoba maple - not maple-like; compound

  • Crimson king maple - burgundy-coloured Norway maple

  • Schwedler - burgundy colour at start of season

That leaves only three: Norway, sugar and red.


  • Red maple Red maple leaves are smaller, often 3-lobed, or approaching 3 lobes, but variable.

  • Norway maple and Sugar maple, which can be difficult to tell apart.
The definitive test is to break the stem. Norway maple leaves have milky sap.
Norway maple leaves seem often bigger and darker green. They have sharper points,
almost bristled, especially at the base. There are more Norway maple in the Glebe.
That said, there seem to be silver-red maple hybrids. 


    

10. Needle-leaved trees

Tips

  • When checking compound leaves for opposite vs alternate arrangement, look at the leaves,
not the leaflets. The leaflets are almost always opposite, regardless.

  • Lobes are not teeth. Oak have lobes, no teeth. Maple have both.

  • The leaves of young saplings can fool you. They can be much bigger than usual and even look different.
