  2 Leaves palmately lobed or bilobed (3, 5, or more veins diverging from the base of the leaf blade into the lobes)
1 Leaves not lobed (entire or serrate, sometimes coarsely so), or only with 2 small auriculate lobes at the base of an otherwise unlobed leaf blade (such as various Magnolia species).
    3 Lianas, shrubs, or trees, not grasses, generally with solid stems.
      4 Shrubs, subshrubs, or trees (sometimes scrambling or occasionally high-climbing with the support of other vegetation, but lacking the specialized climbing structures listed above).
