Acacia simplex is a perennial climbing tree native to islands in the western part of the Pacific Ocean as far east as Savaiʻi. It is also found in Argentina. This tree grows up to 12 m in height.[2]

There is no common English name, but it is called tatakia in Fiji, tatagia in Samoa, tātāngia in Tonga and Martaoui in New-Caledonia


The tree is used as a toxin in fishing. It incapacitates the fish, but it is apparently not harmful to people.[3]
