The three-thorned acacia is a deciduous tree between 9 and 12 m high, whose trunk and branches are covered with branched thorns. Its flowers are greenish in color, arranged in clusters and are much visited by bees. It usually bears abundant fruit every 3-5 years. Its fruits are legumes that twist in a spiral shape.
The wood of the three-spined acacia is used in carpentry and the seed can be used for creams and ice creams. The fruits are sweet and have been used as cattle feed.
