Leaves are in pinnae pairs of 20-40; the leaflets are very small, up to 4 × 0.75 mm. The inflorescence is arranged in white spherical heads. The involucel is located in the lower half of the peduncle. Seed pods are dehiscent. [2]

It produces a pair of straight spines at each node, some of which have large bulbous bases. These swollen spines are naturally hollow and occupied by any one of several symbiotic ant species. The common name of the plant is derived from the observation that when wind blows over bulbous spines in which ants have made entry and exit holes, they produce a whistling noise.
