long. Mature buds are oval to pear-shaped, long and wide with a hemispherical, conical or beaked operculum that is shorter than the floral cup. Flowering occurs from March to September and the flowers are white. The fruit is a woody oval, barrel-shaped or slightly urn-shaped capsule long and wide with the valves enclosed in the fruit. '' Corymbia citriodora'' and '' C. henryi'' are similar to ''C. maculata'' but have a more northerly distribution extending into Queensland. The adult leaves of ''C. citriodora'' are slightly narrower and those of ''C. henryii'' wider than those of ''C. maculata''.

Distribution

''Corymbia maculata'' is a widespread species in open forest from near Bega and north along the coast of New South Wales to near Taree. There is a disjunct population near Orbost in Victoria. It often forms dense, pure stands in forest and often grows on moderately infertile soil. The species is naturalised in Western Australia and South Australia, and in areas of New South Wales and Victoria outside its natural range.
