It has thin stems with smooth bark, lance-shaped adult leaves, flower buds in groups of eleven, white flowers and barrel-shaped to shortened spherical fruit. Description. "Eucalyptus exilis" is a mallee with a whipstick habit, typically grows to a height of and has a lignotuber. The trunk and branches have a covering of smooth, whitish to pale grey over yellow bark that is shed in long thin ribbons. Young plants and coppice regrowth have stems that are square in  cross section and sessile, elliptical to egg-shaped leaves that are long and wide. Adult leaves are the same, slightly glossy green on both sides, elliptical to lance-shaped, long and wide on a petiole long. The flower buds are arranged in leaf axils in groups of eleven on an unbranched peduncle long, the individual buds on pedicels long. Mature buds are oval to pear-shaped, long and wide with a rounded, sometimes pointed operculum. Flowering occurs between August and October and the flowers are white. The fruit is a woody barrel-shaped to shortened spherical capsule long and wide  with the valves enclosed below the level of the rim. The seeds are blackish brown, obliquely pyramidal and long. Taxonomy. "Eucalyptus exilis" was first formally described by Ian Brooker and published in the journal "Nuytsia". The specific epithet is taken from the Latin word "exilis" meaning "slender" in reference to the stems. Distribution. Boyagin mallee has a disjunct distribution in the wheatbelt region of Western Australia where it grows in heathland and shrubland on lateritic ridges in sandy loamy soils. The three main populations are found near Boyagin Rock, around Bindoon and north east of Mount Lesueur. Conservation status. This  eucalypt is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.
