Tubers help plants perennate (survive winter or dry months), provide energy and nutrients, and are a means of asexual reproduction. [1] Stem tubers manifest as thickened rhizomes (underground stems) or stolons (horizontal connections between organisms); examples include the potato and yam.

Tuber is a genus in the fungal family Tuberaceae, with estimated molecular dating to the end of the Jurassic period (156 Mya). [2] It includes several species of truffles that are highly valued as delicacies.
Tuber borchii, known as the whitish truffle or bianchetto truffle, [1] is a small, common species of edible truffle excellent for use in cuisine. Taxonomy [ edit ]
The plants often grow together in crowded colonies and spread by runners at or just under the soil surface. In late summer the plants produce tubers that are twice as long as wide, [9] each typically measuring 0.5 to 5 cm (1 ⁄ 4 to 2 in) in diameter. [8] The plant produces rosettes of leaves and an inflorescence on a long rigid scape.
The plant produces one or more spindle-shaped [5] or cylindrical [11] tubers. The largest may weigh 10 pounds (4.5 kg) and grow one meter (3 ft 3 in) underground. [ 11 ] Dioscorea polystachya is more tolerant to frost and cooler climates than other yams, which is attributed to its successful introductions and establishment on many continents.
