Шаблон:Short description Шаблон:Speciesbox
Eucalyptus thamnoides, also known as brown mallee,[1]Шаблон:Rp is a species of mallee that is endemic to south western Western Australia. It has smooth bark, lance-shaped adult leaves, flower buds in groups of seven, cream-coloured to pale yellow flowers and cup-shaped, conical or bell-shaped fruit.
Description
Eucalyptus thamnoides is a mallee that typically grows to a height of Шаблон:Cvt and forms a lignotuber. It has smooth, pale grey bark. Young plants and coppice regrowth have dull green to greyish, lance-shaped leaves that are Шаблон:Cvt long and Шаблон:Cvt wide. Adult leaves are the same shade of glossy green on both sides, lance-shaped, Шаблон:Cvt long and Шаблон:Cvt wide, tapering to a petiole Шаблон:Cvt long. The flower buds are arranged in leaf axils in groups of seven on a flattened, unbranched peduncle Шаблон:Cvt long, the individual buds on pedicels Шаблон:Cvt long. Mature buds are an elongated oval shape, Шаблон:Cvt long and Шаблон:Cvt wide with a horn-shaped operculum up to twice as long as the floral cup. Flowering occurs from March to July or November and the flowers are cream-coloured to pale yellow. The fruit is a woody cup-shaped, conical or bell-shaped capsule Шаблон:Cvt long and Шаблон:Cvt wide with the valves near rim level or protruding.[2][3][4]
Taxonomy and naming
Eucalyptus thamnoides was first formally described in 2002 by Ian Brooker and Stephen Hopper in the journal Nuytsia from specimens collected by Brooker near Needilup in 1988.[3][5] The specific epithet (thamnoides) is derived from the ancient Greek word thamnos meaning "a bush or shrub" with the ending -oides meaning "like",[6] referring to the habit of this species, in contrast to that of E. astringens.[3]
In the same edition of Nuytsia, Brooker and Hooper described two subspecies, and the names have been accepted by the Australian Plant Census:
- Eucalyptus thamnoides subsp. megista Brooker & Hopper[7] differs from the autonym in having larger flower buds and fruit that are up to Шаблон:Cvt long and Шаблон:Cvt wide;[3]
- Eucalyptus thamnoides Brooker & Hopper subsp. thamnoides[8] has fruit that are Шаблон:Cvt in diameter.[2]
Distribution and habitat
Subspecies megista grows on plains and low rises but not on breakaways and occurs between Quairading, the Stirling Range, Cranbrook and Hopetoun.[3][9] Subspecies thamnoides grows on plains, breakaways, low stony hills and near rivers from near Gnowangerup to the Stirling Range National Park and Jerramungup.[10]
Conservation status
Eucalyptus thamnoides and both subspecies are listed as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[4][9][10]
