Description
Acacia 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. 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. 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 (Cabi, 2019).
