The plant described has many broad leaves with rough edges. Referring to the dichotomous key:

  • It falls under 1b (Leaves are broad), so we go to 2.
  • For 2b, it has many leaves, so we go to 4.
  • Going to 4b, since the leaflet edges are rough, the answer is Juglans nigra.

Therefore, the correct response is juglans nigra.
