Шаблон:Short description Шаблон:Speciesbox

Eucalyptus cuprea, commonly known as the mallee box,[1] is a species of mallee that is endemic to the west coast of Western Australia. It has rough, flaky bark on the base of its trunk, smooth coppery-coloured bark above, lance-shaped adult leaves, flower buds in groups of seven, creamy white flowers and conical to cup-shaped fruit.

Description

Eucalyptus cuprea is a mallee that typically grows to a height of Шаблон:Cvt and forms a lignotuber. It has rough flaky, box-style bark for up to Шаблон:Cvt of the trunk, smooth copper-colour to pale orange-grey bark above. Young plants and coppice regrowth have egg-shaped, dull greyish green leaves that are Шаблон:Cvt long and Шаблон:Cvt wide. Adult leaves are arranged alternately, the same glossy green on both sides Шаблон:Cvt long and Шаблон:Cvt wide on a petiole Шаблон:Cvt long. The flower buds are arranged in groups of seven on an unbranched peduncle Шаблон:Cvt long, the individual buds on a pedicel Шаблон:Cvt long. Mature buds are oval to pear-shaped, about Шаблон:Cvt long and Шаблон:Cvt wide with a rounded operculum, usually with a small point on the tip. Flowering occurs between August and November and the flowers are white or creamy-white. The fruit is a woody conical to cup-shaped capsule Шаблон:Cvt long and Шаблон:Cvt wide on a pedicel Шаблон:Cvt long with the valves deeply enclosed in the fruit.[1][2][3]

Taxonomy and naming

Eucalyptus cuprea was first formally described in 1993 by Ian Brooker and Stephen Hopper from a specimen collected by Brooker north of the Murchison River in 1984.[3][4] The specific epithet (cuprea) is a Latin word meaning "coppery"[5] in reference to the seasonal colour of the smooth bark.[2][3]

Eucalyptus cuprea belongs in Eucalyptus subgenus Symphyomyrtus section Adnataria (also known as the boxes). Within the Adnataria section, E. cuprea is part of a subgroup, series Buxeales which are all found in south-eastern Australia, with only three occurring in Western Australia, those being E.cuprea , E. absita and E. lucasii. All three have inflexed stamens which separates them from the eastern species.[6]

Distribution and habitat

Mallee box is found in a small area in the Geraldton hills in the Mid West region of Western Australia where it grows in shallow sandy soils over granite.[1] It occurs in almost pure stands.[2]

Conservation status

Eucalyptus cuprea is classified as "endangered" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999[7] and as "Threatened Flora (Declared Rare Flora — Extant)" by the Department of Environment and Conservation (Western Australia).[1] An Interim Recovery Plan has been prepared.[8] The main threats to the species include farming activities such as grazing by sheep, weed invasion, land clearing, firebreak maintenance and inappropriate fire regimes.[7]
