Eucalyptus pileata, commonly known as the capped mallee, is a species of mallee that is native to South Australia and Western Australia. It has smooth greyish bark, narrow lance-shaped adult leaves, flower buds in groups of seven, white flowers and cup-shaped, conical or barrel-shaped fruit.
Eucalyptus pileata is a mallee, rarely a small tree, that typically grows to a height of and forms a lignotuber. It has smooth, greyish bark that is shed in long ribbons to reveal orange or yellow new bark. Young plants and coppice regrowth have egg-shaped, bluish green leaves that are long and wide. Adult leaves are narrow lance-shaped, the same shade of glossy green on both sides, long and wide, tapering to a petiole long. The flower buds are arranged in leaf axils on an unbranched peduncle long, the individual buds on pedicels long. Mature buds are cylindrical to oval or pear-shaped, long and wide with a turban-shaped, ribbed operculum long and wide. Flowering occurs from February to May or from September to October and the flowers are white. The fruit is a woody, cup-shaped, conical or barrel-shaped capsule long and wide.[1] [2] [3] [4]
Eucalyptus pileata was first formally described in 1934 by William Blakely in his book A Key to Eucalypts from material collected near Ravensthorpe in 1909.[5] The specific epithet (pileata) is from the Latin pileatus meaning "wearing a pileus", a kind of felt cap, referring to the cap-shaped operculum.[6]
Capped mallee grows in Western Australia and South Australia. It grows in shrubland between Balladonia, Kondinin, Norseman, Nugadong and Ravensthorpe in Western Australia. In South Australia it occurs on the Eyre Peninsula, mainly between the Hincks Conservation Park and Cummins.
This eucalypt is classified as "not threatened" in Western Australia by the Western Australian Government Department of Parks and Wildlife.
