Acacia rhetinocarpa (neat wattle), family Mimosaceae, also known as the resin wattle, is a resinous shrub growing to 0.5-2 m high. Branchlets are sparsely hairy, and the phyllodes are borne on short stem-projections 2–5.5 mm long, 1.5–3.5 mm wide. Inflorescences are simple, with globular heads bearing 12-15 golden flowers. Pods are 1–3.5 cm long, 2–3 mm wide, thinly leathery and hairless . Seeds are longitudinal, oblong, 3.5 mm long, slightly shiny, brown. Flowering occurs from August to October, and the species is likely to be wind-pollinated. Ants are suspected to disperse seeds, although germination may be influenced by disturbance or fire. Acacia rhetinocarpa is related to A. glandulicarpa, and is superficially similar to A. brachyclada from Western Australia. Phyllode shape and size may be similar to some forms of A. Acinacea.

Inappropriate fire and disturbance regimes; with the risks that (i) neat wattle (including the soil seedbank) will become extinct due to exclusion of fire from critical habitat; and (ii) species (including soil seedbank) will become locally extinct if the frequency of fires is too high.
