Structures for vegetative spread


bulb: a storage organ, usually underground, made up of a stem and leaf bases, the food reserves being stored in the inner, fleshy leaf bases.

bulbil: a small, deciduous bulb (or tuber) formed in the axil of a leaf or replacing flowers in an inflorescence, and functioning to propagate the plant vegetatively.

rhizome: an underground stem, usually growing horizontally. cf. runner, stolon.

stolon: a prostrate or trailing stem that produces roots at the nodes. cf. rhizome, runner.

tuber: a storage organ formed by swelling of an underground stem or the distal end of a root.

turion: an over-wintering vegetative bud or specialised short shoot with modified leaves, arising from the stem, often near ground level
