Eucalyptus siderophloia

Eucalyptus siderophloia is a tree that typically grows to a height of and forms a lignotuber. It has hard, rough, furrowed grey or black bark on the trunk and branches, sometimes smooth on the thinner branches. Young plants and coppice regrowth have egg-shaped to lance-shaped leaves that are paler on the lower surface, long and wide. Adult leaves are the same shade of green on both sides, lance-shaped to curved, long and wide, tapering to a petiole long. The flowers are mostly arranged on the ends of branchlets in groups of seven on a branched peduncle long, the individual buds on pedicels long. Mature buds are diamond-shaped or spindle-shaped, long and wide with a conical operculum. Flowering mainly occurs from September to January and the flowers are white. The fruit is a woody cup-shaped or conical capsule long and wide with the valves near rim level. ==Taxonomy and naming==

Eucalyptus siderophloia was first formally described in 1867 by George Bentham in Flora Australiensis. Terri-barri is an Aboriginal word from the Sydney region. The specific epithet (siderophloia) is derived from Greek words meaning "iron" and "bark". ==Distribution and habitat==

This ironbark grows in forests on the coast and adjacent foothills in soils of reasonable fertility, from about Maryborough and Springsure in Queensland to near Sydney in New South Wales. ==Uses==

The sapwood is usually resistant to the lyctus borer. Not an easy timber to work, however it has a beautiful appearance similar to some rainforest species. Uses include flooring and decking, shipbuilding, poles, construction, railway sleepers and heavy engineering. ==References==
