The plant has high-climbing, thorny vines. The underground part is a tuber — a swollen, food-storage stem, much like an Irish potato.
Tubers develop from either the stem or the root. Stem tubers grow from rhizomes or runners that swell from storing nutrients while root tubers propagate from roots that are modified to store nutrients and get too large and produce a new plant.
