Small tree or mallee to 8 m tall with grey-black ironbark on trunk and larger branches, and smooth whitish bark on smaller branches. Juvenile leaves are circular, blue-green and dull. The adult leaves are spear-shaped, 7-11 cm long, 1-2.5 cm wide, grey-green and glossy. Buds spindle-shaped, 6-8 mm long, 2-3 mm wide. The bud cap is rounded.
