Keying Exercise (3)

Tree 1: Cedrus spp.
Keying Steps: 1', 2' 3, 4' --> Group 3 (trees with needle-like leaves)-->1', 2, 3'

Tree 2: Parkinsonia aculeata
Keying steps: 1', 2', 3', 5, 6', 7' --> Group 6 (trees with pinnately and bipinnately compound, alternate leaves)--> 1', 3, 4, 5

I had some trouble with the second tree. At first, I thought it was apart of group 5, having what I thought were opposite leaves. I didn't realize they were alternate. The term "forked" in 6:5 helped me identify it.
