The ascending, thin, hairy or glabrous and evergreen phyllodes have a linear shape that can be slightly incurved with a length of 4 to 8 cm (1.6 to 3.1 in) and a width of 1 to 3 mm (0.039 to 0.118 in) and have three to seven impressed, distant and resinous nerves.

[2] It blooms between August and October producing simple inflorescences that occur singly or in pairs in the axils with spherical flower-heads that have a diameter of 4 to 7 m (13 to 23 ft) and contain 15 to 35 light to bright yellow coloured flowers.

It was reclassified as Racosperma viscidulum in 1987 by Leslie Pedley then transferred back to genus Acacia in 2006.

In Queensland the range extends as far west as Injune and in New South Wales as far west as around Coonabarabran where it is found un upland areas with granite based soils and is usually a part of low woodland communities along with species of Eucalyptus and other Acacias.

[2] In New South Wales it is mostly located in the Tablelands Region from around Tamworth in the south out to Mount Kaputar National Park in the west and to around Tenterfield in the west where it is usually part of dry sclerophyll forest communities or among the heath in crevices of granite outcrops.
