This species was first described as Chrysophyllum polynesicum by William Hillebrand in 1888, two years after his demise. Then Henri Ernest Baillon transferred it to the genus Nesoluma, all of  whose constituent species were later incorporated into the genus Sideroxylon as a result of phylogenetic analyses. References
