Ironbark

Ironbark is a common name of a number of species within the genus Eucalyptus that have dark, deeply furrowed bark.Ian Brooker, "Botany of the Eucalypts" in J.J.W. Coppen, Eucalyptus, 3-35, Boca Raton, Florida: CRC Press, 2002 , p. 31

Many eucalypts shed their bark very year, but on an Ironbark the dead bark stays on the trees, forming the furrows. It becomes rough after drying out and becomes full of kino, a dark red tree sap exuded by the tree.CSIRO Forest Products Newsletter 1946 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 bark protects the epicormic buds which allow the tree to reshoot.J.B. Reid & B.M. Potts, "Eucalypt Biology" in Reid et al. (eds.), Vegetation of Tasmania, Australian Government, 2005, pp. 198-223
