''Eucalyptus sideroxylon'', or mugga, red ironbark or mugga ironbark, is a small to medium-sized or occasionally tall tree. The bark is persistent on the trunk and large branches, hard and deeply furrowed, dark grey to black, with upper limbs smooth and whitish. Adult leaves are stalked, lanceolate to 14 x 1.8 cm, sub-glaucous or dull green. Flowers are white, pink, red or pale yellow from early autumn until mid-spring. Distribution is wide but sporadic: south-eastern Queensland, widespread on the western slopes and plains of New South Wales south into north-central Victoria. ''E. sideroxylon'' is very conspicuous with its unusually black bark often holding copious quantities of kino. It is a very popular ornamental and street tree, Ferntree gully road in Melbourne has an avenue of muggas planted. In the wild muggas grow on infertile soils, often little more than sandy gravel. A former suspecies, ''Eucalyptus sideroxylon'' subsp. ''tricarpa'' L.A.S.Johnson is currently regarded as a species in its own right - ''Eucalyptus tricarpa'' (L.A.S.Johnson) L.A.S.Johnson & K.D.Hill. == Uses == The wood is relatively hard and dense, and is often used for firewood. It has very high resistance to rotting and can be used for fence posts, piers, sleepers. Heartwood dark red, sapwood pale yellow. Very dense, hard, fine grained timber, difficult to work, but polishes to a high sheen. Has been used for furniture, turnery, boat-building, benchtops. Popular as a craft furniture timber during the 1990s and early 2000s, Nicholas Dattner famously used ironbark that had been submerged as a wharf pier for 80 years in a range of tables. At about 1130 kg/m3 it is one of the few timbers that will not float. The leaves are used in the production of cineole based eucalyptus oil.〔Boland, D.J., Brophy, J.J., and A.P.N.
