woody tuber - tuberous rootstock.
a woody swelling at the base of the shoot system below or just above the ground, containing adventitious buds from which new shoots develop if the top of the plant is cut off or burnt (common in the shrubby eucalypts ('mallee') and in many other fire-tolerant Australian shrubs).
a woody swelling that occurs at or just below ground level on many fire tolerant plants
a woody tuber developed in the axils of the cotyledons or the first few leaf pairs, becoming massive in many mature trees or mallees, possessing embedded vegetative buds for regeneration following crown destruction, for example by fire
conspicuous swelling at base of stem, at or below soil-level, containing dormant buds
A woody swelling, partly or wholly underground at the base of the stem of certain plant species, notably many Eucalypts. It is composed of energy reserves and dormant buds which can emerge as a survival response to an externally applied stress eg: fire, drought or soil compaction.
A lignotuber is a root or woody stem base that stores water.
A lignotuber is a starchy swelling on underground stems or roots. Jarrah and mallee plants use them as a life support system in case of fire or animal damage. They are able to sprout back from buds on the surface of the lignotuber.
