Classification of the genus Acacia (in the wider sense) has been subject to considerable debate. It is generally agreed that there are valid reasons for breaking it up into several distinct genera, but disagreement in the way this should be done. Some authorities have wanted to transfer this species to the genus Racosperma, but the latest decision (in 2011 and still not fully accepted) is that it remains in Acacia[
Closely related to A. Tindaleae, it is also close to A. Arbiana[
]. The plant is vegetatively similar to A. Ruppii[
]. Sometimes confused with A. Brunioides which is distinguished by its terete to subterete phyllodes[
]. Phyllodes may superficially resemble some forms of A. Lineata[
Racosperma confertum (A.Cunn. ex Benth.) Pedley
Acacia conferta is a shrub or small tree growing up to 4 metres tall[
]. Although it produces leaves as a seedling, llike most members of the genus the mature plant does not have true leaves but has leaf-like flattened stems called phyllodes[
The flowers have been suggested as a source of essential oils for perfumery[

Succeeds in drier areas of the subtropical and tropical zones.
This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[
The flowers possess a remarkable perfume and have been suggested as a source of essential oils for use in perfumery[
The seed of most, if not all, members of this genus has a hard seedcoat and may benefit from scarification before sowing to speed up germination. This can usually be done by pouring a small amount of nearly boiling water on the seeds (being careful not to cook them!) and then soaking them for 12 - 24 hours in warm water. By this time they should have imbibed moisture and swollen - if they have not, then carefully make a nick in the seedcoat (being careful not to damage the embryo) and soak for a further 12 hours before sowing.
