Eucalyptus farinosa is an ironbark tree that typically grows to a height of and forms a
lignotuber. It has hard, dark grey to black bark to the small branches. Young plants and
coppice regrowth have
glaucous stems and leaves, the leaves
petiolate, more or less round, long and wide. Adult leaves are arranged alternately, the same dull green glaucous colour on both sides, elliptical to egg-shaped or broadly lance-shaped, long and wide on a petiole long. The flower buds are arranged in groups of seven on a branching
peduncle long, the individual buds on
pedicels long. Mature buds are glaucous, oval to spindle-shaped, long and wide with a conical
operculum. Flowering has been recorded in October and the flowers are white. The fruit is a woody, glaucous, cup-shaped to barrel-shaped
capsule long and wide on a pedicel up to long with longitudinal ribs and the valves close to rim level. ==Taxonomy and naming==
