The glabrous shrub or tree typically grows to a height of 1 to 4 metres (3 to 13 ft) but can be as high as 7 m (23 ft) and has corky, deeply furrowed gery coloured bark. Like most species of Acacia it has phyllodes rather than true leaves. The green to grey-green to blue-green leathery textured phyllodes have an inequilaterally obovate-elliptic to duck's head shape and are broadest above the middle with a conspicuously rounded upper margin and a straight lower margin. The phyllodes are usually 4 to 9 cm (1.6 to 3.5 in) in length and 2 to 6 cm (0.79 to 2.36 in) wide with three to eight main longitudinal nerves with anastomosing minor nerves. It blooms from April to June and produces yellow flowers.
It is endemic to arid areas in the Kimberley and Pilbara regions of Western Australia where it is often situated on sand dunes and pindan country growing in red sandy or sandy-loamy soils. The range of the plant extends from the northern boundary of the Pilbara region northwards to around Broome in the north west to around Kumpupintil Lake and Lake Gregory in the east and is sometimes found on heavier, sometimes saline, soils.
