The bushy shrub typically grows to a height of 1.2 to 6 metres (4 to 20 ft)[1] and has a dense habit.

It has dark red-brown to grey coloured bark that is longitudinally fissured at base of main trunks.

The glabrous, coriaceous to thinly crustaceous pods have a length of up to 10 cm (3.9 in) and a width of 4 mm (0.16 in).

It was reclassified as Racosperma connianum by Leslie Pedley in 2003 then transferred back to the Acacia genus in 2006.

[2] It is native to an area along the south coast of the Goldfields-Esperance region of Western Australia from around the east of Esperance at Cape Le Grand to east of Cape Arid National Park around Israelite Bay where it is found amongst granite outcrops growing in shallow skeletal soils with isolated populations around Pingelly.
