Identification Key
1. Bark rather smooth, tightly adherent; stems below new growth with conspicuous lenticels; pith continuous at the nodes; tendrils unbranched; leaf blades unlobed, coarsely toothed, the surfaces glabrous to glabrate (sometimes hirtellous on the veins)
2
1. Bark furrowed, in longitudinal strips and fibers, sometimes peeling; lenticels inconspicuous; pith with diaphragms at the nodes; tendrils branched; leaf blades lobed or unlobed, coarsely to shallowly toothed, the surfaces glabrous to densely hairy
4
2. Infructescence of 2-8 berries, the berry >1.5 cm wide, thick-skinned with moderate pulp, with lenticels; seed <7 mm long; panhandle and north Florida
2. Infructescence of 4-30 berries, the berry <1 cm wide, thin-skinned with little pulp, lacking lenticels; seed <7 mm long; mostly peninsular Florida
3
3. Leaf blades mostly 4-8 cm wide, with 8 or more teeth per side; raphe of seed broad and rounded; various habitats of the peninsula
3. Leaves 2-3.5 cm wide, with 7 or fewer teeth per side; raphe of seed narrow and ridged; vines usually shrub-like or trailing, at times weakly climbing scrub of Polk, Highlands Counties)
4. Leaf blade densely white, gray-white, to reddish white tomentose on the lower surface, the surface (except the veins) not visible
4. Leaf blade glabrate to arachnoid on the lower surface, the surface generally visible
5
5. Leaves arachnoid to hirtellous, especially on the lower surface, rarely subglabrous; teeth of leaf blade often shallow, less frequently pronounced with a wide triangular base, usually ca. 1 mm long or less
6
5. Mature leaf blades glabrous or with pubescence limited to tufts of hairs in axils of main veins on lower surface and sometimes on upper petiole, green beneath; teeth of leaf blade mostly pronounced on a wide triangular base, usually >1 mm high
7
6. Young stems terete, nodes not red-banded; leaf blade unlobed to deeply lobed, the lower surface glaucous (sometimes somewhat obscured by hairs); fruits 8-20 mm wide, glaucous; generally of mesic to xeric habitats
6. Young stems slightly to distinctly angled, nodes sometimes red-banded; leaf blade unlobed to obscurely lobed, the lower surface not glaucous; fruits 4-8 mm wide, not or slightly glaucous; generally of mesic to hydric habitats
7. Young stems purplish red to reddish chestnut; nodal diaphragm 2.5-4 mm thick; leaf blade lobed, the lobes acuminate
7. Young stems gray, green, brown, or suffused purplish partially or on one side only; nodal diaphragm 1-2.5 mm thick; leaf blade unlobed or obscurely lobed, the lateral lobes acute (rarely acuminate), the central lobe acute to acuminate
