tuber

an enlarged underground root or stem containing PARENCHYMA cells packed with STARCH for overwintering. The best known example is the stem tuber of potato which has buds in the axils of tiny leaves (forming the potato ‘eyes’). Root tubers often have a finger-like branched structure, as in the lesser celandine, Ranunculus ficaria.
