Synonyms: Acacia drepanolobium

Wikipedia Abstract

Vachellia drepanolobium (syn. Acacia drepanolobium), commonly known as Whistling Thorn (family Fabaceae), is a swollen-thorn vachellia native to East Africa. The whistling thorn grows up to 6 meters tall. It produces a pair of straight thorns at each node, some of which have large bulbous bases. These swollen thorns are naturally hollow and occupied by any one of several symbiotic ant species.
