Eucalyptus fusiformis is a tree that typically grows to a height of and forms a
lignotuber. It has thick, hard, greyish ironbark on the trunk and on branches more than about in diameter. Young plants and
coppice regrowth have stems that are more or less square in cross-section and leaves that are
petiolate, egg-shaped to broadly lance-shaped, long and wide. Adult leaves are lance-shaped to curved, the same dull green on both sides, long and wide on a petiole long. The flower buds are arranged in groups of seven on the ends of branchlets on a compound
peduncle long, the individual buds on
pedicels long. Mature buds are oval to spindle-shaped, long and wide with a conical
operculum. Flowering occurs between May and August and the flowers are white. The fruit is a woody hemispherical, conical, pear-shaped or oval
capsule long and wide with the valves below rim level. ==Taxonomy and naming==
