Eucalyptus pyriformis, commonly known as pear-fruited mallee or Dowerin rose,[1] is a species of low, straggly mallee that is endemic to Western Australia. It has smooth greyish brown bark sometimes with ribbony bark near the base, egg-shaped to lance-shaped adult leaves, flower buds in groups of three, red, pinkish or creamy white flowers and down-turned, conical fruit with prominent ribs.

Description

Eucalyptus pyriformis is a straggly mallee that typically grows to a height of Template:Cvt and to a width of Template:Cvt and forms a lignotuber. In nature, it tends to be multi-stemmed but in cultivation it is more likely to be single stemmed. The bark is smooth, grey or salmon-pink coloured, often shedding in ribbons at the base. Young plants and coppice regrowth have leaves that are arranged alternately, dull bluish green, egg-shaped to broadly lance-shaped, Template:Cvt long and Template:Cvt wide and petiolate. Adult leaves are the same shade of dull bluish or greyish green on both sides, egg-shaped to lance-shaped, Template:Cvt long and Template:Cvt wide, tapering to a petiole Template:Cvt long. Mature buds are oval, Template:Cvt long and Template:Cvt wide with ribs on the sides and a beaked operculum. Flowering occurs between May and October and the flowers are red, pinkish or creamy white flowers. The fruit is a woody, pendent, conical capsule Template:Cvt long and Template:Cvt wide on a pedicel Template:Cvt long and with prominent ribs on the sides.[1][2][3][4][5][6]

Taxonomy

Eucalyptus pyriformis was first formally described by the botanist Nicolai Stepanovitch Turczaninow in 1849 in the journal, Bulletin de la Société Impériale des Naturalistes de Moscou.[7][8] The specific epithet (pyriformis) is a Latin word meaning "pear-shaped".[9]

Distribution and habitat

Pear-fruited mallee grows in flat and gently undulating country between the Murchison River in the north and Dowerin, Goomalling and Cowcowing in the south.[1][2][4]

Ecology

The flowers of E. pyriformis provide abundant nectar and pollen as a food source for wildlife.[3]

Conservation status

This eucalypt is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[2]

Use in horticulture

Eucalyptus pyriformis is distinctive for its large, pendulous buds and spectacular coloured flowers.[6] It is sold commercially as tube stock or as seeds and is planted as an ornamental, as a light screen, habitat for birds and insects and as wind protection. It can tolerate drought and light frost, will grow in coastal or inland areas.[5]
