Oca tubers
A tuber, or stem tuber, is a development of a stolon, or above-ground rhizomeTemplate:Fact, thickened for use as a storage organ. The tuber usually, though not always, develops when the stolon becomes subterranean, such as in a potato. This modified stem forms at the end of a lateral branch. Auxiliary buds are located at the nodes. When the buds develop, adventitious roots and rhizomes form below them. This should not be confused with a tuberous root, sometimes called a root tuber, such as a sweet potato or Dahlia.
