Eucalyptus persistens is a species of tree, rarely a
mallee, that typically grows to a height of and forms a
lignotuber. It has rough, dark grey bark on the trunk and branches. Young plants and
coppice regrowth have dull, bluish, linear to narrow lance-shaped leaves that are long and wide. Adult leaves are lance-shaped, the same shade of green on both sides, long and wide, tapering to a
petiole long. The flower buds are mostly arranged on the ends of branchlets on a branched
peduncle in groups of seven. The peduncles are long, the individual buds on
pedicels long. Mature buds are oval to pear-shaped, long and wide with a conical, rounded or beaked
operculum. Flowering occurs between April and October and the flowers are white. The fruit is a woody, cup-shaped or barrel-shaped
capsule, long and wide with the valves near rim level. ==Taxonomy==
