Acacia kempeana (Acacia or ακακία (akakia) from the Greek word Akis for thorn and kempeana after Pastor Kempe, co-founder of Lutheran Mission at Hermannburg-Ntaria in 1877), commonly known as wanderrie wattle, witchetty bush^[1] or granite wattle, is a shrub in subfamily Mimosoideae of family Fabaceae that is endemic to arid parts of central and western Australia.

Description

The Wanderrie wattle grows as a spreading shrub or tree with many stems typically to a height of 1 to 6 m (3 ft 3 in to 19 ft 8 in) but can reach over 10 m (33 ft).^[2] It has furrowed, usually grey or brown coloured bark and terete, glabrous terete branchlets that are slightly scurfy.^[1] Like most Acacia species, it has phyllodes rather than true leaves. These are a bright green to grey-green or blue-green colour, flat, up to around 9 cm (3.5 in) in length and 1.5 cm (0.59 in) wide. The phyllodes have a narrowly elliptic to narrowly elliptic, sometimes narrowly oblanceolate shape.^[1] The flowers between January or April and September^[2] are yellow, and held in cylindrical clusters 1 to 2 cm (0.39 to 0.79 in) in length. The pods are papery, about 7 cm (2.8 in) long and 1.5 cm (0.59 in) wide.

Taxonomy

The species was first formally described by the botanist Ferdinand von Mueller in 1882 as part of the work Remarks on Australian Acacias as published in the Australasian Chemist and Druggist. It was reclassified as Racosperma kempeanum in 1987 by Leslie Pedley then transferred back to the genus Acacia in 2006.^[3] It is closely related to Acacia sibirica, Acacia duriuscula and Acacia aprepta.^[1]

Uses

Witchetty grubs are a traditional staple food in arid regions. These larvae feed on the roots of the witchetty bush (for which they are named), as well as other Acacia species.^[4] The bush also provides edible gum and seeds.

Distribution

The shrub is widely distributed through arid and semi-arid inland areas of Western Australia,^[2] South Australia, the Northern Territory and Queensland. It is often found growing on stony hillsides^[1] and in a variety of soil types,^[2] especially coarse textured alluvium, and can often form part of mulga woodland communities on plains with sandy to loamy soils.^[1]

Cultivation

The shrub can be propagated from scarified seeds or seeds pre-treated in boiling water. It grows well in an open, sunny and reasonably well-drained position and is suitable for most soil types. It is a hardy species in dry and low maintenance areas, well noted for being both drought and frost tolerant.^[5]

Acacia kempeana est une espèce d'arbustes de la famille des Mimosaceae selon la classification classique, ou de celles des Fabaceae selon la classification phylogénétique. Endémique à l'Australie, il est largement répandu dans les zones arides et semi-arides de l'intérieur de l'Australie-Occidentale, l'Australie-Méridionale et le Territoire du Nord.

Description

C'est un arbuste à port étalé avec plusieurs tiges, d'une hauteur d'environ quatre mètres. Comme la plupart des espèces d'Acacia, il a des phyllodes plutôt que de vraies feuilles. Elles sont de couleur vert brillant, plates, mesurantjusqu'à neuf centimètres de long et un cm et demi de large. Les fleurs sont jaunes, groupées en grappes cylindriques et mesurent entre un et deux centimètres de long. Les gousses sont minces comme du papier, d'environ sept centimètres de long et un cm et demi de large.

Usages

Son nom commun anglais Witchetty Bush renvoie au fait que les Aborigènes consomment les chenilles d'Endoxyla leucomochla (appelées communément Witchetty grub) qui parasitent ses racines. Il fournit également une gomme et des graines comestibles.
