About

Acacia hamersleyensis, also known as Karijini wattle or Hamersley Range wattle, is a species of flowering plant in the family Fabaceae and is endemic to the north-west of Western Australia. It is a spreading, shrubby, sometimes spindly shrub or tree with narrowly elliptic, leathery, slightly asymmetric phyllodes, spikes of golden yellow flowers and narrowly oblong, firmly papery pods.

Where it grows

Karijini wattle is mostly restricted to the Pilbara region of north-western Western Australia, mostly in the Hamersley Range around Newman in the east extending through Wittenoom and Paraburdoo in the west with small outlier populations in the Carnarvon Range in the Little Sandy Desert. It is usually grows along ridges and on the higher slopes of ranges, in rocky gullies and on scree slopes, occasionally in creeklines that flow down from the ranges. It grows in iron-rich skeletal soils over ironstone bed rock.
