| Tree | Description |
|---|---|
| pines | have long, thin needles that usually grow in bundles of two to five |
| hemlocks | have very short, flat needles growing on little stalks on each branch. Each needle is dark green on the top side and lighter green underneath. |
| fir trees | have single needles that grow directly on the twig, not on a stalk. Their cones grow only on the top side of the branch, pointing upward. |
| spruce trees | have short, four-sided needles that grow in spirals on stalks. Their cones grow on the bottom side of the branch, pointing down. |
| oak trees | most easily distinguished by their fruits, which are called acorns. Their leaves grow in an alternate pattern, with a leaf on one side of the branch, a space, and then a leaf on the other side of the branch. |
