Corymbia dichromophloia is a tree that typically grows to a height of and forms a
lignotuber. It has smooth white, sometimes powdery bark, sometimes with thin, unshed orange and brownish flakes on the trunk and upper branches. Young plants and
coppice regrowth have egg-shaped to broadly lance-shaped or elliptical leaves that are long and wide and
petiolate. Adult leaves are arranged alternately, the same shade of dull or slightly glossy green on both sides, lance-shaped or curved, long and wide, tapering at the base to a petiole long. The flower buds are arranged on the ends of branchlets on a branched
peduncle long, each branch of the peduncle with seven, sometimes nine or eleven buds on
pedicels long. Mature buds are oval, pear-shaped or spherical, long and wide with a rounded
operculum. Flowering occurs between February and May and the flowers are creamy white. The fruit is a woody, urn-shaped
capsule long and wide with a descending disc and the valves enclosed in the fruit. The seeds are reddish brown and boat-shaped with a wing on the end. ==Taxonomy and naming==
