Tubers




For the fungal genus, see Truffle .


A tuber is a part of a Rhizome thickened for use as a Storage Organ . It is usually, though not always, Subterranean , such as 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 such as a Sweet Potato or '' Dahlia '', which is a similarly swollen Root .
