It has mostly smooth bark, a crown containing juvenile, intermediate and adult leaves, flower buds in groups of seven, white flowers and sessile, cup-shaped to hemispherical fruit.Eucalyptus kitsoniana is a tree or mallee that typically grows to a height of 10 m (33 ft) and forms a lignotuber.

Juvenile leaves are sessile, arranged in opposite pairs, a lighter shade of green on the lower side, broadly lance-shaped to more or less round, up to 100 mm (3.9 in) long and 80 mm (3.1 in) wide.

The flower buds are arranged in leaf axils in groups of seven on an unbranched peduncle 5–25 mm (0.20–0.98 in) long, the individual buds sessile and the groups surrounded by bracts when young.
