A lignotuber is a starchy swelling of the root crown possessed by some plants as a protection against destruction of the plant stem by fire. The crown contains buds from which new stems may sprout, and a sufficient store of nutrients to support a period of growth in the absence of photosynthesis.
Plants possessing lignotubers include Eucalyptus marginata (Jarrah), most mallees, and many Banksia species.
Many plants with lignotubers grow in a shrubby habit, but with multiple stems arising from the lignotuber. The term lignotuberous shrub is widely used to describe this habit. Lignotubers survive more than other plants.
[edit] Fire ecology
Lignotubers are part of fire ecology and plant adaptation and regeneration, such as chaparral genera and species.
