This ‘species’ in fact isn’t a species in the common sense, it is most probably not monophyletic, that means the species’ name covers more than one species.

The Polynesian populations extend from Fiji into central Polynesia (Cook Islands, Society Islands) and east Polynesia (Tuamotu Archipelago). The western populations may be native, the central and eastern, however, were most probably imported by early Polynesian settlers.

There is still a lot to discover …. [1][2][3][4][5]

The taxonomy of this species is very confusing, it is thought to contain several varieties, of which some, of course, may not be valid at all.

The species contains at least two subspecies, of which one, the nominate form, is of Melanesian origin, occuring in Polynesia only on a few islands within the Fijian and Tongan islands, while the other one, ssp. atollensis (H. St.John) M.-H. Sachet is endemic to eastern Polynesia, where it occurs with three varieties on the Pitcairn Islands, the Society Islands and in the Tuamotu Archipelago.
