The flower buds are arranged in leaf axils in groups of seven on an unbranched peduncle Шаблон:Cvt long, the individual buds on a pedicel Шаблон:Cvt long. Mature buds are spherical to oval, Шаблон:Cvt long and Шаблон:Cvt wide with a rounded operculum. Flowering occurs between August and February and the flowers are white. The fruit is a woody conical to hemispherical capsule Шаблон:Cvt long and Шаблон:Cvt wide with the valves protruding above the rim.[1][2][3]

Taxonomy and naming

Eucalyptus ewartiana was first formally described in 1919 by Joseph Maiden from a specimen he collected near Pindar in 1909. The description was published in Journal and Proceedings of the Royal Society of New South Wales.[4][5] The specific epithet (ewartiana) honours Alfred James Ewart.[2][5]

Distribution and habitat

Ewart's mallee is found on sandplains and among granite outcrops and is spread throughout the Mid West, Wheatbelt, Pilbara and Goldfields-Esperance regions of Western Australia where it grows in loamy-sandy soils.[1][3]

Conservation status

This eucalypt is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[1]
