Description

Eucalyptus concinna is a mallee that typically grows to a height of Шаблон:Cvt or sometimes a tree to Шаблон:Cvt and forms a lignotuber. It has rough grey-brown, thick to flaky for the lower half of the trunk with pale grey or coppery smooth bark above. Young plants and coppice regrowth have stems that are square in cross section, and egg-shaped to broadly lance-shaped leaves that are Шаблон:Cvt long and Шаблон:Cvt wide. Adult leaves are glossy green and arranged alternately with a blade that is lance-shaped, Шаблон:Cvt long and Шаблон:Cvt wide on a petiole Шаблон:Cvt long. The flower buds are arranged in groups of seven, nine or eleven in leaf axils on and unbranched peduncle Шаблон:Cvt long, the individual buds on a pedicel Шаблон:Cvt long. Mature buds are oblong to pear-shaped, Шаблон:Cvt long and Шаблон:Cvt wide with a conical, rounded, flattened or turban-shaped, operculum Шаблон:Cvt long that is wider than the floral cup at the join. The buds are often orange or red immediately before flowering. Flowering occurs sporadically, probably depending on rainfall and the flowers are white. The fruit is a woody, cup-shaped, sometimes conical capsule Шаблон:Cvt long and Шаблон:Cvt wide on a pedicel Шаблон:Cvt long.[1][2][3][4][5]

Taxonomy

Eucalyptus concinna was first formally described by the botanists Joseph Maiden and William Blakely in 1929 from a specimen collected by Richard Helms in 1891 during the Elder Exploring Expedition.[6][7] The specific epithet (concinna) is a Latin word meaning "well-arranged", "skilfully joined", "beautiful" or "striking",[8] "probably referring to the habit and overall appearance of the plant".[1]

Distribution

Victoria Desert mallee grows in red sand or red clayey sand or sandy loam in sandplains or sandhill areas. It is distributed throughout the Goldfields-Esperance and Mid West regions of Western Australia[2] and the west of South Australia as far east as the Gawler Ranges.[1][2]

Conservation status

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