The leathery grey-green coloured phyllodes have a linear to narrowly elliptic shape are straight to slightly curved with a length of 9 to 20 cm (3.5 to 7.9 in) and a width of 4 to 12 mm (0.16 to 0.47 in) and have many closely parallel nerves of which one to three are more prominent than the others.

[1] The species was first formally described by the botanist Leslie Pedley in 1978 as part of the work A revision of Acacia Mill.

It was reclassified by Pedley as Racosperma maranoense in 1987 then transferred back to genus Acacia in 2001.

[3] The plant has a limited range in the Roma and Mitchell area of southern Queensland where it is found growing in texture contrast soils often as a part woodland communities featuring stands of Eucalyptus populnea.

It is commonly situated on plains or flat terrain, that can be periodically inundated following rainfall events growing in dark brown, heavy clay loamy soils that usually are quite boggy once wet.
