answeredThe plant has many broad leaves with rough edges. Based on the dichotomous key:
1b indicates the leaves are broad, which leads us to step 2. Going to 2b, we see that it has many leaves. We then go to step 4. In step 4, since the leaflet edges are rough, it corresponds to Juglans nigra.
Therefore, the correct answer is Juglans nigra.
