Eucalyptus dorrigoensis is a tree that typically grows to a height of and forms a
lignotuber. It has smooth, slightly powdery white, grey or pink bark, sometimes with slabs of rough bark near the base. Young plants and
coppice regrowth have warty stems, the leaves arranged in opposite pairs and egg-shaped to broadly lance-shaped, long and wide. Adult leaves are the same colour on both sides, lance-shaped to curved, long and wide on a
petiole long. The flower buds are arranged in groups of seven in leaf
axils on an unbranched
peduncle long, the individual buds on a
pedicel long. Mature buds are oval, long and wide with a conical
operculum. Flowering occurs in May and the flowers are white. The fruit is a woody conical or hemispherical
capsule long and wide with the valves extended beyond the rim. ==Taxonomy and naming==
