bulb

A bulb is a storage organ (and/or reproductive organ) in which nutrients are stored in mostly fleshy cataphylls (and/or leaf bases) which are arranged on a shortened stem. Mostly, the bulbs are formed underground (e. g. in Allium – bulb). However, daughter bulbs may also develop aboveground (e. g. in the inflorescence of Allium oleraceum – Field Garlic).
