Eucalyptus lockyeri, commonly known as Lockyer's box,[1] is a species of small tree endemic to a small area in Queensland. It has rough bark near the base of the trunk, smooth bark above, lance-shaped adult leaves, flower buds in groups of seven, white flowers and hemispherical fruit.
Description
Eucalyptus lockyeri is a small tree that typically grows to a height of Шаблон:Cvt and forms a lignotuber. It has rough, fibrous to flaky bark on the base of the trunk, smooth grey to brownish bark above. Young plants and coppice regrowth have dull bluish, lance-shaped to egg-shaped leaves that are Шаблон:Cvt long and Шаблон:Cvt wide. Adult leaves are the same dull bluish grey on both sides, Шаблон:Cvt long and Шаблон:Cvt wide, tapering to a petiole Шаблон:Cvt long. The flower buds are arranged in groups of seven in leaf axils on an unbranched peduncle Шаблон:Cvt long, the individual buds on pedicels Шаблон:Cvt long. Mature buds are sometimes glaucous, oval, Шаблон:Cvt long and Шаблон:Cvt wide with a conical to horn-shaped operculum, Flowering has been recorded in March, May and December and the flowers are white. The fruit is a woody, hemispherical capsule Шаблон:Cvt long, Шаблон:Cvt wide, sometimes glaucous at first, with the valves protruding above the rim of the fruit.[2][3][4]
Taxonomy and naming
Eucalyptus lockyeri was first formally described in 1991 by Donald Blaxell and Ken Hill from a specimen collected by Blaxell near Ravenshoe in 1978, and the description was published in the journal Telopea.[4][5] The specific epithet (lockyeri) "honours Michael Lockyer of Ravenshoe, who first drew the authors' attention to this taxon".[4]
In 1994, Ian Brooker and David Kleinig described two subspecies and the names have been accepted by the Australian Plant Census:
- Eucalyptus lockyeri subsp. exuta Brooker & Kleinig[6] has leaves, buds and fruit that are not glaucous;[2]
- Eucalyptus lockyeri subsp. lockyeriBlaxell & K.D.Hillsubsp. lockyeri[7] has glaucous leaves, buds and fruit.[2]
Distribution and habitat
Eucalyptus lockyeri is endemic to a restricted area of Queensland, occurring between Ravenshoe and near Herberton. It usually grows on slopes and ridges in poor, rocky soil.[2][4]
Conservation status
Both subspecies of E. lockyeri are classified as "least concern" under the Queensland Government Nature Conservation Act 1992.[8][9]
