Description

The multi-stemmed shrub with a height of 3 to 4 m (9.8 to 13.1 ft) eventually mature to a tree with a height of 6 to 10 m (20 to 33 ft) with an obconic habit with dense crowns. The densely haired branchlets have discrete resinous ribs towards the apices. Like most species of Acacia it has phyllodes rather than true leaves. The evergreen and variable phyllodes are straight and dimidiate to sickle shaped recurved and usually with a narrowly oblong to elliptic shape. The phyllodes are not rigid and have a length of 2 to 8 cm (0.79 to 3.15 in) and a width of 2 to 12 mm (0.079 to 0.472 in) with many longitudinal nerves.[1]

A. caesaneura if often situated on plains or undulating country growing in red-brown sandy loam to clay soils sometimes over hardpan as a part of Acacia shrubland or woodland communities.[1]
