Madeira vine is a long-lived (perennial), twining or climbing plant growing over taller plants. The stems are hairless (glabrous) and grow in a twining fashion. Younger stems are green or reddish in colour and round in cross-section. They become rope-like in appearance and turn greyish-brown in colour as they mature. Distinctive greyish-brown or greenish-coloured warty tubers often form at the joints (nodes) along the older stems. These wart-like tubers are very characteristic.
