Description
Eucalyptus oligantha is a tree that typically grows to a height of Шаблон:Cvt and forms a lignotuber. It has rough, fibrous, flaky or scaly greyish bark on the trunk and branches. Young plants and coppice regrowth have egg-shaped to more or less round leaves Шаблон:Cvt long, Шаблон:Cvt wide and petiolate. Adult leaves are broadly egg-shaped to more or less round and are usually lost in the dry season. They are usually the same shade of green on both sides, Шаблон:Cvt long and Шаблон:Cvt wide on a petiole Шаблон:Cvt long. The flower buds are mostly arranged on the end of branchlets on a thin, branched peduncle in groups of three or seven. The peduncle is Шаблон:Cvt long, the individual buds on pedicels Шаблон:Cvt long. Mature buds are oval to pear-shaped, Шаблон:Cvt long and Шаблон:Cvt wide with a usually conical operculum. Flowering has been recorded in March, July and September and the flowers are creamy yellow to whitish. The fruit is a woody, cup-shaped to more or less cylindrical, bell-shaped or conical capsule Шаблон:Cvt long and Шаблон:Cvt wide with the valves either level with the rim or strongly protruding.[1][2][3]
Taxonomy and naming
Eucalyptus oligantha was first formally described in 1843 by Johannes Conrad Schauer in Walpers' Repertorium Botanices Systematicae.[4][5] The specific epithet (oligantha) is from the ancient Greek oligos meaning "few" and -anthus meaning "-flowered".[6][7]
Distribution and habitat
Broad-leaved box grows on flats and slopes, often near watercourses in forest and woodland in the Kimberley region between Wyndham and Derby with a few scattered populations in the Northern Territory, including some of its offshore islands.[2][3]
Conservation status
This eucalypt is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[1]
