Description

Eucalyptus deccorticans is a tree that typically grows to a height of Шаблон:Cvt and forms a lignotuber. It has hard, dark grey to black ironbark on the trunk and larger branches, smooth white to greyish or yellow bark on the thinner branches. Young plants and coppice regrowth have leaves that are narrow lance-shaped, a lighter colour on the lower surface, Шаблон:Cvt long and Шаблон:Cvt wide. Adult leaves are lance-shaped to curved, the same dull colour on both sides, Шаблон:Cvt long and Шаблон:Cvt wide on a petiole Шаблон:Cvt long. The flower buds are arranged in leaf axils in groups of seven on a peduncle Шаблон:Cvt long, the individual buds on a pedicel Шаблон:Cvt long. The buds are club-shaped to spindle-shaped or diamond-shaped, Шаблон:Cvt long and Шаблон:Cvt wide with a conical operculum. Flowering has been observed in April, August and September and the flowers are white. The fruit is a woody conical, cup-shaped or barrel-shaped capsule Шаблон:Cvt long and Шаблон:Cvt wide on a pedicel Шаблон:Cvt long.[1][2]

Taxonomy and naming

Gum-top ironbark was first formally described in 1911 by Frederick Manson Bailey from a specimen collected near Eidsvold by Thomas Lane Bancroft. Bailey gave it the name Eucalyptus siderophloia f. decorticans and published the description in the Queensland Agricultural Journal.[3][4] In 1921, Joseph Maiden raised the form to species level as Eucalyptus decorticans, publishing the change in his book A Critical Revision of the Genus Eucalyptus.[5][6] The specific epithet (decorticans) is derived from the Latin word decorticans meaning "without bark" referring to the peeling bark on the smaller branches.[1]

Distribution and habitat

Eucalyptus decorticans grows in open forest on hills and hillsides in stony clay soils. It is widespread in southeastern Queensland.[1][2]

Conservation status

This eucalypt is classified as "least concern" under the Queensland Government Nature Conservation Act 1992.[7]
