On favourable sites in its natural habitat A. auriculiformis grows 25-35 m tall with a straight bole dominant for a greater part of tree height. More commonly it is 8-20 m tall and rarely a shrub 3-5 m, heavily branched and with a short bole. The bark is grey or brown, sometimes blackened at the base, smooth in young trees, becoming rough and longitudinally fissured with age (Doran and Turnbull, 1997;Turnbull and Awang, 1997). The phyllodes are falcate, 8-20 cm long and 1.0-4.5 cm wide, glabrous, greyish-green and thinly textured. There are three prominent longitudinal veins running together towards the lower margin or in the middle near the base, with many fine, crowded secondary veins, and a distinct gland at the base of the phyllode (Pedley, 1975, 1978;Maslin and McDonald, 1996). The inflorescence is an axillary, somewhat interrupted spike to 8.5 cm long in pairs in the upper axils. Flowers are light-golden in colour, 5-merous, bisexual, tiny, sessile, fragrant;calyx tubular, up to 0.1 cm long, shortly lobed, glabrous;corolla to 0.2 cm long;stamens many, about 0.3 cm long;ovary densely pubescent. The pods are strongly curved to form an open coil, flat, flexible but hard, rather woody, glaucous, transversely veined with undulate margins and are about 6.5 cm long by 1.5 cm wide. They are initially straight or curved, but on maturity become twisted and irregularly coiled. The shiny black seeds, held transversely in the pod, are broadly ovate to elliptical, 0.4-0.6 cm long by 0.3-0.4 cm wide, and each is encircled by a long red, yellow or orange funicle;areole large, almost enclosed.
