Ironbark is a common name of a number of species in three taxonomic groups within the genusEucalyptus that have dark, deeply furrowed bark.
Instead of being shed annually as in many of the other species of Eucalyptus, the dead bark accumulates on the trees, forming the fissures. It becomes rough after drying out and becomes impregnated with kino, a dark red tree sap exuded by the tree. The bark is resistant to fire and heat and protects the living tissue within the trunk and branches from fire. In cases of extreme fire, where leaves and shoots are removed, the protective bark aids in protecting epicormicbuds which allow the tree to reshoot.
