Shrub to small tree 2-5 m high with erect to fastigiate branches ; rarely a tree up to 12 m high. Twigs are angular, covered with a whitish down, often of a fawn hue. Phyllodes are 10-20 cm long and 1.5-5.0 cm wide, covered with silky, flattened hair, provided with a mucronate tip. There are three conspicuous major nerves the central one joining with the 2 lateral at the bottom and extending to the mucro at the tip. Secondary nerves anastomosing to form a reticulate network, with a small gland at the bottom of the apex on the upper face of the blade. Flowers golden-yellow in spikes 2-5 cm long ; peduncles 3-7 mm ; minute, spathulate, early deciduous bractlets 1 mm long. Pods rolled and irregularly twisted 2..5-4 mm wide, leathery, seeds with a bright yellow aril. Life span ca 10 years, propagation by seeds only, with a moderate ability to coppice and a weak ability to suckering.
It requires high temperatures and no frost ("m" > 8-10°C).
In its home land A. holosericea occurs under MAR rainfall belts of 300 mm and up to 600 and above, with a 3-4 month summer rainy season. It has been successfully established in many places in Sahel with a MAR above 500 mm.
It is sensitive to alkalinity and to salinity. A. holosericea appears to be less demanding in phosphorus than native acacias of Sahel, responding to very low P fertilization or even to endomycorrhyzation only.
