IRONBARKS have a clean tall trunk with upright but sparse branches. The bark has a rugged black grey appearance. As it name suggests, it is a very good and hard timber.

Leaves broad, silvery, opposite and stalkless. Relatively short trunk and spreading crown. - This ironbark commonly occurs on dark, fertile soils derived from basalt although it will also grow on stony soils or shallow clays. The presence of SILVER-LEAVED IRONBARK is almost always an indication that there is ironstone in the soil.
BLUE-LEAVED IRONBARK (E FIBROSE)
Leaves narrow, ashy coloured, generally a small tree. Leaves alternate. Fruit 6-12mm - This is a tree often found on sandy soils or stony ridges. It does well on skeletal soil and often grows in association with BLACK CYPRESS PINE.
NARROW-LEAVED IRONBARK (E CREBRA)
Leaves long and narrow, dull green, alternate and stalked. Fruits small, 4-5mm - The Narrow-leaved Ironbark is a tree of deep sandy soil' flat or slightly undulating topography and is often mixed with White Cypress Pine.
