Acacia maconochieana

Acacia maconochieana, also known as Mullan wattle,[1] is a shrub or tree of the genus Acacia and the subgenus Plurinerves that is endemic to an arid area of central Australia.


The shrub or tree typically grows to a height of 2.5 to 12 metres (8 to 39 ft)[2] and has longitudinally fissured, grey coloured bark and densely haired branchlets. Like most species of Acacia it has phyllodes rather than true leaves. The hairy, evergreen phyllodes have a linear shape with a length of 8 to 18 cm (3.1 to 7.1 in) and a width of 2 to 5 mm (0.079 to 0.197 in) with many fine and closely parallel nerves.[1] It blooms in October and produces yellow flowers.[2]


The species was first formally described by the botanist Leslie Pedley in 1986 as a part of the work Acacia maconochieana (Mimosaceae), a new species from semi-arid Australia as described in the journal Austrobaileya. It was reclassified by Pedley as Racosperma maconochieanum in 2003 then returned to genus Acacia in 2006.[3]


It is native to an area in the Northern Territory and the Kimberley and Goldfields-Esperance regions of Western Australia and is commonly situated along the margins of lakes that are periodically flooded growing in sandy or loamy soils.[2] The range of the plant extends from around Gregory Salt Lake in the west through to around Nongra Lake in the Tanami Desert in the east where it is usually a part of low open forest or woodland or open scrubland communities.[1]

Aboriginal names[edit]

The Walmajarri people of the Paruku IPA in the Kimberley call this wattle Wirimangurru.[4] Other Aboriginal names are:Jaru: gunanduru, wirrimangurru and Ngarinyman: Gunadurr.[5]
