Eucalyptus kitsoniana is a tree or mallee that typically grows to a height of and forms a
lignotuber. It has smooth white to grey bark, sometimes with accumulated slabs of rough bark near the base and ribbons of shed bark above. The crown contains a mixture of juvenile, intermediate and adult leaves. 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 long and wide. Adult leaves are arranged alternately, the same glossy green on both sides, long and wide on a flattened
petiole long. The flower buds are arranged in leaf axils in groups of seven on an unbranched
peduncle long, the individual buds sessile and the groups surrounded by
bracts when young. Mature buds are oval to oblong, long and wide with a conical to rounded
operculum. Flowering occurs between August and March and the flowers are white. The fruit is a sessile, cup-shaped to hemispherical
capsule, long and wide, the valves near rim level. ==Taxonomy and naming==
