Since the hypocotyl is a region between the stem and the roots, such tubers are variable in their anatomy and growth habits. Thus the roots of Cyclamen graecum grow from the base of the tuber, suggesting it is a stem tuber, whereas those of Cyclamen hederifolium mostly grow from the upper surface of the tuber, suggesting it is a root tuber.

The roots are an extensive and complex system of fine, fibrous roots and scaly rhizomes with small, hard, spherical tubers and basal bulbs attached. The tubers are 0.3–2.5 cm ( 1 ⁄ 8 –1 in) in diameter and the colors vary between yellow, brown, and black.
In some species (e.g. Cyclamen coum) roots come from the bottom of the tuber, suggesting that it is a stem tuber; in others (e.g. Cyclamen hederifolium) roots come largely from the top of the tuber, suggesting that it is a root tuber. [6] As an example of a combination, juno irises have both bulbs and storage roots. [7]
The plant has high-climbing, thorny vines. The underground part is a tuber — a swollen, food-storage stem, much like an Irish potato. The plant has high-climbing, thorny vines. The underground ...
A geophyte (earth+plant) is a plant with an underground storage organ including true bulbs, corms, tubers, tuberous roots, enlarged hypocotyls, and rhizomes.Most plants with underground stems are geophytes but not all plants that are geophytes have underground stems.
Freshly dug sweet potato plants with tubers Hemerocallis tuber roots. A root tuber, tuberous root or storage root is a modified lateral root, enlarged to function as a storage organ. The enlarged area of the tuber can be produced at the end or middle of a root or involve the entire root.
Tuber crisps (chips) Many species have edible roots, prized for millennia as a reliable source of starch and carbohydrates, even during the winter. Some are edible raw, though are less bitter when cooked. [8] They can be harvested by hand or by treading the mud in late fall or early spring, causing light root tubers to float to the surface. The ...
The subterranean tubers fragment readily when disturbed, and any remaining tuber material can give rise to a new plant. The subterranean tubers can survive for between five and ten years. It can spread at ground level, as a rhizome, and vine stems can form roots at any leaf node in contact with soil, which in turn can produce new subterranean ...
