1 Lianas.
  2 Lianas climbing by adventitious roots
  2 Lianas climbing by twining or by tendrils.
    3 Lianas climbing by tendrils.
      4 Tendrils branched, leaf-opposed; leaves mostly 5-7-lobed, the margins also serrate or dentate
      4 Tendrils simple (though paired in Smilax in SMILACACEAE), axillary; leaves 3-lobed, the margins entire, serrulate, or prickly.
        5 Leaves longer than wide, entire or prickly-margined; stems usually obviously armed with prickles; flowers 6-merous, greenish, in umbels borne in leaf axils; tendrils stipular, 2 per leaf axil, adnate to the petiole basally
        5 Leaves wider than long, entire or serrulate; stems not armed; flowers 5-merous, blue-purple or yellow, solitary or in small fascicles in leaf axils; tendrils 1 per leaf axil
1 Trees or shrubs. {add: Vernicia in EUPHORBIACEAE, Firmiana in MALVACEAE, Kalopanax in ARALIACEAE, Ficus in MORACEAE}
             7 Leaves > 3 dm long and wide; tree monopodial, with a single, unbranched stem (rarely with a few branches).
               8 Leaf lobes > 15, not sublobed; venation of each lobe parallel; fruit a drupe, with 1 seed; [Monocots]
               8 Leaf lobes < 13, most of these sublobed; venation of each lobe pinnate; fruit either a many-seeded berry or a single-seeded nutlet; [Eudicots].
                 9 Petiole attachment marginal; leaf lobes mostly sublobed; fruit a large berry, with many seeds
                 9 Petiole attachment peltate; leaf lobes not sublobed; fruit an nutlet, single-seeded
             7 Leaves < 3 dm long and wide; tree branching; [Eudicots].
                   10 Leaves 2-lobed (deeply notched at the apex, each lobe separated by the midvein, asymmetrical; [peninsular FL and s. TX]
                   10 Leaves 3-5 (-7) lobed; [collectively widespread].
                     11 Leaf blades (3-) 5 (-7) lobed, to 15 cm wide and long, each lobe finely serrate-crenate (>3 teeth per cm of margin) and rarely with a small sub-lobe; multiple fruit spherical and spiky, consisting of multiple bird-beak-like loculicidal capsules; buds axillary
                     11 Leaves 3 (-5)-lobed, to 35 cm wide and long, each lobe coarsely toothed or sublobed, the teeth or sublobes (at most 1-2 per cm of margin) attenuate-acuminate; multiple fruit spherical and merely rough on the surface, consisting of multiple achenes with tawny bristles; buds infrapetiolar (completely hidden in the swollen petiole base)
                              15 Leaves 10-30 cm long and wide; fruit a berry; inflorescence of solitary to a few flowers, or a raceme
                              15 Leaves 2-10 cm long and wide; fruit an aggregate of drupelets; inflorescence a cyme
