Eucalyptus longirostrata is a tree that typically grows to a height of Шаблон:Cvt but does not form a lignotuber. It has smooth grey bark that is shed in strips. Young plants have broadly lance-shaped leaves that are paler on the lower surface, Шаблон:Cvt long and Шаблон:Cvt wide. Adult leaves are glossy green on the upper surface, paler below, lance-shaped, Шаблон:Cvt long and Шаблон:Cvt wide tapering to a channelled petiole Шаблон:Cvt long. The flower buds are arranged in groups of seven in leaf axils on a flattened, unbranched peduncle Шаблон:Cvt long, the individual buds on pedicels Шаблон:Cvt long. Mature buds are oval, Шаблон:Cvt long and Шаблон:Cvt wide with a long, beaked operculum. Flowering has been recorded in February and March and the flowers are white. The fruit is a woody, hemispherical to cup-shaped capsule Шаблон:Cvt long and Шаблон:Cvt wide with the valves protruding above the rim of the fruit.[1][2]
Taxonomy and naming
This grey gum was first formally described in 1934 by William Blakely who gave it the name Eucalyptus punctata var. longirostrata and published the description in his book A Key to the Eucalypts.[3] In 1988, Lawrie Johnson and Ken Hill raised the variety to species status as E. longirostrata, publishing the change in Flora of Australia.[4] The specific epithet (longirostrata) is from the Latin words longus meaning "long"[5]Шаблон:Rp[6]Шаблон:Rp and rostratus meaning "beaked",[2][5]Шаблон:Rp[6] referring to the long, beaked operculum.[2]
Distribution and habitat
Eucalyptus longirostrata grows in open forest on hills and ridges in Queensland, between the Blackdown Tableland and the Toowoomba district.[1]
Conservation status
This eucalypt is classified as "least concern" under the Queensland Government Nature Conservation Act 1992.[7] It was also listed as a least concern species with the International Union for the Conservation of Nature in 2019 with a stable, although severely fragmented, population of over 2,000 individuals.[8]
