Bell Vine is a short-lived creeping or climbing vine often twining up, or scrambling over, other plants. Its slender stems are covered in close-lying or spreading hairs. Its alternately arranged leaves (25-80 mm long) are usually somewhat heart-shaped in outline. Its small, bell-shaped, white flowers (9-13 mm long) are borne singly or in clusters of two or three in the leaf forks its fruit is a small papery capsule (5-7 mm long) containing four brown seeds.
