They are nonlobed, simple leaves and are attached oppositely on the branch.

Explanation:

A dichotomous key is a tool you use in biology to know the identity of things in nature such as trees,flowers, fish or even rocks. This key has choices that follow each other in a progressive manner, where one choice led to the other until you identify the item.In this case, to identify Dogwood, you follow the below steps;

1b. Broad leaf = Step 2

2b. Simple leaf = Step 7

7a. Leaf bases attached opposite each other on branch = Step 8

8b. Leaves not lobed = Step 9

9b. Leaves not heart shaped = Dogwood

The key is (1b,2b,7a,8b,9b)
