Шаблон:Short description Шаблон:Speciesbox
Acacia acanthoclada, commonly known as harrow wattle,[1] is a species of flowering plant in the family Fabaceae and is endemic to southern continental Australia. It is a low, highly branched, spreading and spiny shrub with wedge-shaped to triangular or egg-shaped phyllodes with the narrower end towards the base, and spherical heads of up to 30 flowers, and linear, spirally-coiled pods.
Description
Acacia acanthoclada is a low, highly branched, spreading shrub that typically grows to a height of Шаблон:Cvt, and has softly-white branchlets ending in sharp, tapering points. The phyllodes are erect, wedge-shaped to triangular or egg-shaped with the narrower end towards the base, Шаблон:Cvt long and Шаблон:Cvt wide. The flowers are borne in globe-shaped heads on a raceme Шаблон:Cvt in diameter on a peduncle Шаблон:Cvt long, the heads usually with 15 to 30 yellow flowers. Flowering occurs from July to December and the pods are linear but spirally coiled, up to Шаблон:Cvt long, Шаблон:Cvt wide, leathery, dark brown to black, and glabrous. The seeds are Шаблон:Cvt long with a thick aril.[1][2][3][4][5]
Taxonomy
The species was formally described in 1863 by Victorian Government Botanist Ferdinand von Mueller in his Fragmenta Phytographiae Australiae, based on plant material collected near Kulkyne.[6][7]
In 1999, Bruce Maslin described two subspecies of A. acanthoclada in the journal Nuytsia and the names are accepted by the Australian Plant Census:[8]
- Acacia acanthoclada F.Muell. subsp. acanthoclada[9] has green phyllodes, or if glaucous, then not wider that Шаблон:Cvt, the phyllodes glabrous or hairy, with seeds Шаблон:Cvt long.[5][10][11][12]
- Acacia acanthoclada subsp. glaucescens Maslin[13] has glaucous or more or less glaucous phyllodes, Шаблон:Cvt wide, the phyllodes glabrous, with seeds Шаблон:Cvt long.[14][15]
Distribution and habitat
Harrow wattle grows in a variety of vegetation types and is relatively common in Western Australia, South Australia, Victoria and New South Wales.
- Subspecies acanthoclada is widespread in southern Australia from near Wubin through South Australia to north-western Victoria and Dareton in the south-west of western New South Wales.[10][5][11][12]
- Subspecies glaucescens is restricted to scattered locations in south-western Western Australia, and is found in the Koolanooka Hills Шаблон:Cvt east of Morawa, Evanston about Шаблон:Cvt north of Koolyanobbing and Mount Correll about Шаблон:Cvt west-north-west of Koolyanobbing.[14][15]
Conservation status
Both subspecies of Acacia acanthoclada are listed as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions,[10][14] but subsp. acanthoclada is listed as "endangered" under the New South Wales Government Biodiversity Conservation Act 2016.[11]
