Breynia officinalis has often been included within the much more widespread species, B. vitis-idaea, but it can be distinguished by the differences in leaf shape (rounded, not acute, apex) and the presence of a basal stalk on the fruits[
This species may be transferred to the genus Phyllanthus. A paper by Warren L. Wagner and David H. Lorence ‘A nomenclator of Pacific oceanic island Phyllanthus (Phyllanthaceae), including Glochidion’ PhytoKeys 4:67-94 (2011)[
], has proposed submerging the genera Breynia, Glochidion, Reverchonia, Phyllanthodendron, and Sauropus into a broadened concept of the genus Phyllanthus. This proposal has not yet (2014) been fully accepted, although the ‘World Checklist of Selected Plant Families’ has accepted the name changes of the Pacific Island species of Glochidion, as detailed in the paper. No revised form of this name has been seen as yet
