Maple leaves have 5 main points, one in the center, and 2 smaller ones on each side. Each point has a vein that begins at the base of the leaf where its stem is located. It will also have varying smaller veins branching from those.

Oak leaves have a very unique shape. They are long, and have rounded points that extend in the direction of the leaf's growth. The veins will branch off into these points, from a larger center vein that grows from the stem.

The American Elm is the State Tree of Massachusetts. These leaves are round/oval shaped, with small pointed ridges around the edges of the leaf. They have a large central vein running down the center.

Birch leaves are similar to Elm leaves, but they are more "teardrop" shaped, with a pointed end. They also have a main central vein. Birch trees are also likely to have white/lighter bark, but not all species have this feature.

Beech leaves are long and pointed. These leaves have smaller ridges along the edges of the leaf. They also have a large vein running down the center. The smaller veins that branch off reach the very edge of the leaf.

Dogwood leaves have a large center vein, just like most leaves on this list. They are oval shaped, with a pointed end. But, unlike other similar leaves, Dogwood tree leaves lack ridges. The edges are smooth all around.
