Seedling: Cotyledons very closely resemble those of ordinary cucumber cotyledons, are thick and oblong, with many spreading hairs on the top and bottom. The stem below the cotyledons (hypocotyl) is also covered with many short hairs that typically point downward.
Stems: Stems are hairy especially at the leaf nodes, longitudinally ridged, and climb by way of branched tendrils.
Leaves: Alternate, 2-8 inches long, 2-8 inches wide, hairy, broadly heart shaped with 5 pointed lobes and a toothed margin.
