It has rough, fibrous to flaky bark on the trunk, smooth bark above, lance-shaped or curved adult leaves, flower buds in groups of seven, white or creamy white flowers and cup-shaped or barrel-shaped fruit.

Eucalyptus volcanica is a tree that typically grows to a height of 25 m (82 ft) and forms a lignotuber.
