Manitoba Maple Acer negundo
Family: Aceraceae (Maple)
Other names: Box-elder, Ash-leaf Maple
This is a very common tree in many areas. It especially grows
well along river and stream banks. It is different from the other
maples in a few ways. Most obviously (in the summer) it has
compound leaves. Differing from the other maples, it often
retains most of its keys all winter long (like some Ashes as well). It twigs are often covered with a white waxy "bloom"
Manitoba Maple twig. Usually they are reddish-purple, and have a white, waxy coating called a "bloom".

Lateral buds and leaf scars (which meet in the middle of the twig)
The white "bloom" rubs off easily. Also, notice how the leaf scars on either side of the twig
meet in the middle.
Often the twigs are a light yellow-green. Depending where on the tree they are growing, twigs vary
in size, colour, and presence of the bloom.

scrubby appearance and retained keys (most obvious on the front right tree).
